Diagnostic Fault Information



Circuit/System Description



The cruise control switch is an input to the body control module (BCM). The BCM monitors the cruise control on/off, set/coast, resume/accelerate



and cancel switches via the cruise control switch signal circuit in order to detect when the driver has requested to perform a cruise control function.



The BCM detects a specific voltage signal on the cruise control switch signal circuit when a switch is applied. The BCM sends a serial data



message to the engine control module (ECM) indicating the status of the cruise control switches.



Conditions for Running the DTC



* The cruise switch is ON.



* The ignition is ON.



Conditions for Setting the DTC



* The BCM detects an invalid voltage signal on the cruise control switch signal circuit for greater than 2 seconds and sends a serial data



message to the ECM. The ECM sets these DTCs when the message is received.



* The ECM runs this diagnostic every 0.05 second.

DTC P0963



- Line Pressure Control (PC) Solenoid Control Circuit High Voltage



Diagnostic Fault Information



Circuit/System Description



The line pressure control (PC) solenoid is part of the control solenoid valve assembly which has no serviceable components. The normally high line



PC solenoid regulates and directs the PC solenoid oil pressure to the pressure regulator valve and isolator valve. Increasing line PC solenoid



pressure increases transmission line pressure. The transmission control module (TCM) varies the current to the line PC solenoid through a low side



driver. Decreasing the current to the line PC solenoid increases line PC solenoid oil pressure by closing OFF the solenoid exhaust port. Increasing



the current to the line PC solenoid decreases line PC oil pressure by opening the solenoid exhaust port. Line PC solenoid power is supplied by the



TCM through a high side driver (HSD). The HSD protects the circuit and components from excessive current flow. If excessive current flow is



detected, the HSD will turn OFF. When the fault is corrected the HSD will reset.



Conditions for Running the DTC



* The engine speed is greater than 400 RPM for 5 seconds.



* The ignition voltage is 8.6 volts or greater.



Conditions for Setting the DTC



P0961



The TCM detects an internal electrical malfunction of the line PC solenoid where the measured line PC solenoid current does not equal the



commanded line PC solenoid current for 5 seconds.

Conditions for Setting the DTC



* The ECM detects the TP sensor angle is less than 2 percent or greater than 13 percent when the throttle actuator control motor is deactivated.



* The condition exists for greater than 1 second or for a cumulative of 10 seconds.



Action Taken When the DTC Sets



DTC P1551 is a type A DTC.



Conditions for Clearing the DTC



DTC P1551 is a type A DTC.



Diagnostic Aids



* The scan tool has the ability to operate the throttle actuator control system using Special Functions. This function operates the throttle



through the entire range in order to determine if the throttle body and system operate correctly.



* Inspect for a condition in which the throttle valve may have been held open.



* Inspect for conditions in which ice may have formed in the throttle bore.



* The throttle valve is spring loaded to a slightly open position. This is referred to as the rest position. The throttle valve should not be



completely closed, nor should it be open any greater than predetermined amount. The throttle valve should move open and to the closed



position without binding under the normal spring pressure. The throttle should NOT be free to move open or closed WITHOUT spring



pressure.

Body - Non-Approval of Clipping For Collision Repair



INFORMATION



Bulletin No.: 07-08-98-001A



Date: January 28, 2009



Subject:



Non-approval of "Clipping" (Sectioning of Two Vehicles) For Collision Repair



Models:



2000-2010 GM Passenger Cars and Trucks (Including Saturn and Saab)



2003-2010 HUMMER H2, H3, H3T



Supercede:



This bulletin is being revised to add model years through 2010. Please discard Corporate Bulletin Number 07-08-98-001 (Section 08 - Body and



Accessories).



General Motors does not approve the use of "clipping" to repair collision damage to vehicles. In the collision repair industry, "clipping" refers to



cutting two damaged vehicles through the windshield pillars, the rocker panels, and across the floor pan and joining the undamaged portions from



these vehicles to make the repair.



The use of "clipping" voids GM's New Vehicle Limited Warranty (and any variety of the GM Protection Plan, as well as GM's new vehicle service



part and corrosion warranties) for each part in the clip.



GM does not sanction clipping repair because it cuts across the major load-bearing paths of a vehicle and can reduce the structural integrity of the



repaired vehicle. This is extremely critical because of the increase in the use of Advance High Strength Steel (AHSS). Improper repairs can lead to



vehicle performance issues related to noise, vibration and handling problems.



GM recommends replacing body components at factory seams. When applicable, GM will provide a specific service part for collision repair frames,



or provide repair information on how to create specific parts from a complete service assembly. Frame repair procedures for select GM vehicles are



available at http://www.goodwrench.com/gmgoodwrenchjsp/gmspo/techrepair_index.jsp. These parts and procedures provide a practical and



cost-effective alternative to clipping. GM provides vehicle specific collision repair procedures which are developed to be in a location and fashion



2010 Cadillac Truck Escalade/ESV RWD V8-6.2L Page 226



that will yield panel strength comparable to the original panel strength. Replacing damaged parts of a vehicle designed to crush in a collision may



reduce occupant protection in a future collision.



GM has not tested or validated a "clipped vehicle" repair; therefore, GM cannot endorse this type of repair or confirm the crash performance during



a subsequent collision. GM recommends the use of genuine GM parts in repairs to help ensure the vehicle is returned to pre-collision condition.

The engine control module (ECM) supplies voltage to each fuel injector on the injector high voltage supply circuits. The ECM energizes each fuel



injector by grounding the high voltage control circuit of the fuel injector. The ECM monitors the status of the injector high voltage supply circuits



and the fuel injector high voltage control circuits. When a fuel injector circuit condition is detected by the ECM, the affected fuel injector(s) is



disabled.



Conditions for Running the DTC



* The engine is running.



* The ignition voltage is between 11-18 V.



* The DTCs run continuously when the above conditions are met.

Diagnostic Fault Information



Typical Scan Tool Data



Circuit/System Description



Based on input speed and output speed signals, signals from the engine control module (engine speed and throttle opening) and vehicle speed,



smooth lock-up control and slip is performed through the lock-up control solenoid (SLU). The SLU is linearly turned ON and OFF. The lock-up



clutch inside the torque converter is operated, and the pump impeller and turbine runner are connected. Through this, the engine and the automatic



transmission are coupled and engine output is connected directly to the automatic transmission, eliminating transmission loss. By sliding the



lock-up clutch when lock-up is in the OFF range, extends the lock-up range to low vehicle speeds. It also suppresses a rise in engine speed and



increases transmission efficiency, improving fuel economy and at the same time, through the sliding of the lockup clutch, engine vibration can be



absorbed by the torque converter.

Circuit/System Description



The ignition system on this engine uses an individual coil/module for each cylinder. The engine control module (ECM) controls the spark event for



each cylinder through the eight individual ignition control circuits. When the ECM commands the ignition control circuit ON, electrical current will



flow through the primary winding of the ignition coil, creating a magnetic field. When a spark event is requested, the ECM will command the



ignition control circuit OFF, interrupting current flow through the primary winding. The magnetic field created by the primary winding will



collapse across the secondary coil windings, producing a high voltage across the spark plug electrodes. The ECM uses information from the



crankshaft position sensor, and the camshaft position sensor for sequencing and timing of the spark events.



Conditions for Running the DTC



* The engine is running.



* The ignition voltage is greater than 6 V.



* DTC P0351-P0356 runs continuously when the above conditions are met.



Conditions for Setting the DTC



The ECM detects that the commanded state of the driver and the actual state of the control circuit do not match for greater than 5 s.



Action Taken When the DTC Sets



DTCs P0351-P0356 are Type B DTCs.



Conditions for Clearing the MIL/DTC



DTCs P0351-P0356 are Type B DTCs.



Diagnostic Aids



A high resistance condition on any ignition control circuit can cause an engine misfire without setting DTC P0351-P0356.

Electrical Ground Repair Overview



Proper electrical system function relies on secure, stable and corrosion-free electrical ground connections. Loose, stripped, or corroded connections



increase the possibility of improper system function and loss of module communication. These conditions may also lead to unnecessary repairs and



component replacement.



In general, electrical ground connections are accomplished using one, or a combination of the following attachment methods:



- Welded M6 stud and nut



- Welded M6 nut and bolt



- Welded M8 nut and bolt



Determine which attachment method is used and perform the appropriate or alternative repair as described in this bulletin.

Circuit/System Description



The tire pressure monitor (TPM) system has a radio frequency (RF) transmitting pressure sensor in each wheel/tire assembly. As vehicle speed



increases, centrifugal force closes the sensors internal roll switch, which puts the sensor into Rolling mode. The body control module (BCM)



receives and translates the data contained in the tire pressure sensor RF transmissions into sensor presence, sensor mode, and tire pressure. Once



vehicle speed is greater than 40km/h (25 mph), the BCM waits for the first sensor to go into Rolling mode, then checks if all sensors have gone into



Rolling mode. If one or more sensors do not go into these modes, or do not transmit at all, the BCM will set DTC C0750, C0755, C0760, or C0765



respectively.



Conditions for Running the DTC



Vehicle speed is greater than 40 km/h (25 mph).



Conditions for Setting the DTC



* A sensor does not transmit for 18 minutes.



* A sensor low battery condition.



Action Taken When the DTC Sets



* The tire pressure monitor indicator icon on the instrument panel cluster (IPC) flashes for 1 minute and then remains illuminated after the



ignition switch is cycled ON and the IPC bulb check is complete.

Suspension - Shock Absorber/Strut Fluid Leak Information



INFORMATION



Bulletin No.: 05-03-08-002E



Date: May 31, 2012



Subject: Information on Diagnosis and Replacement of Shock Absorber and Strut Due to Fluid Leak



Models:



2013 and Prior GM Passenger Cars and Trucks



Supercede:



This bulletin is being revised to add the 2013 model year. Please discard Corporate Bulletin Number 05-03-08-002D (Section 03 - Suspension).



This bulletin is intended to help identify the severity of shock absorber and strut fluid seepage. Improper diagnosis may lead to components being



replaced that are within the manufacturer's specification. Shock absorbers and strut assemblies are fluid-filled components and will normally exhibit



some seepage. Seepage is defined as oil film or dust accumulation on the exterior of the shock housing. Shock absorbers and struts are not to be



replaced under warranty for seepage. Use the following information to determine if the condition is normal acceptable seepage or a defective



component.



2010 Cadillac Truck SRX FWD V6-3.0L Page 42



Important



Electronically controlled shock absorbers (MR) may have a tendency to attract dust to this oil film. Often this film and dust can be wiped



off and will not return until similar mileage is accumulated again.



Inspection Procedure



Note



The shock absorber or strut assembly DOES NOT have to be removed from the vehicle to perform the following inspection procedure.



Use the following descriptions and graphics to determine the serviceability of the component.



Shock Absorbers



Do Not Replace shock absorbers displaying condition 1 or 2 levels of seepage.



1. Oil or fluid residue only on the bottom or top of the shock absorber and not originating from the shaft seal (the upper part of the lower shock



tube).

Body - Stain/Film On Windshield Glass Perimeter



TECHNICAL



Bulletin No.: 09-08-48-006



Date: September 18, 2009



Subject: Clear Stain or Film on Inside Perimeter of Windshield Glass (Clean/Polish Glass)



Models:



2010 and Prior Passenger Cars and Trucks (Including Saturn and Saab)



2010 and Prior HUMMER H2, H3



Condition



Some customers may comment on a clear stain or film on the inside of the windshield glass. This condition appears along the outer edges of the



glass along the top, bottom or A-pillar areas. Normal glass cleaning procedures will not remove the stain.



Cause



The assembly plant uses a clear sealer/primer on the outer edge of the windshield glass to improve adhesion to the urethane adhesive that bonds the



windshield glass to the vehicle body. Excess sealer/primer may drip or flow onto the windshield and cause a stain. Once the sealer/primer dries, it



may appear to have etched the glass.



Correction



Note



A "white" type of toothpaste is recommended for this repair. Gel-type toothpaste may provide less satisfactory results.



Use a small amount of toothpaste on a soft, cotton cloth to polish the stained area. It may be necessary to wrap the cloth around a paint stir stick or a



similar tool to reach the lower corners of the windshield glass.



After polishing the glass, clean the inside of the windshield glass with a clean, damp, cotton cloth and verify all of the stain is removed. Do not use



any cleaners or solvents - use only clean warm water.

Tires - Information On Proper Tire Pressure



INFORMATION



Bulletin No.: 00-00-90-002K



2010 Cadillac Truck SRX FWD V6-3.0L Page 17



Date: September 14, 2012



Subject: Information on Proper Tire Pressure



Models:

Supercede:



This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 00-00-90-002J (Section 00 - General Information).



Important



- Adjustment of tire pressure for a customer with a Low Tire Pressure Monitor (TPM) light on and no codes in the TPM system is



NOT a warrantable repair. Claims to simply adjust the tire pressure will be rejected.



- ALL tires (including the spare tire) MUST be set to the recommended inflation pressure stated on the vehicle's tire placard (on



driver's door) during the PRE-DELIVERY INSPECTION (PDI). Recommended inflation pressure is not the pressure printed on tire



sidewall.



- Tires may be over-inflated from the assembly plant due to the mounting process.



- Generally a 5.6掳C (10掳F) temperature change will result in (is equivalent to) a 6.9 kPa (1 psi) tire pressure change.



- 2008-2009 HUMMER H2 Only - The H2 comes standard with Light Truck "D" Load Range tires with a recommended cold inflation



pressure of 289 kPa (42 psi). These tires will alert the driver to a low pressure situation at roughly 262 kPa (38 psi) due to a



requirement in FMVSS 138 which specifies a Minimum Activation Pressure for each tire type. This creates a relatively narrow



window of "usable" pressure values and the warning will be more sensitive to outside temperature changes during the colder



months.



As with other cold temperature/tire pressure issues, there is nothing wrong with the system itself. If a vehicle is brought in with this



concern, check for tire damage and set all tires to the Recommended Cold Inflation Pressure shown on the vehicle placard.



Accurate tire pressures ensure the safe handling and appropriate ride characteristics of GM cars and trucks. It is critical that the tire pressure be



adjusted to the specifications on the vehicle's tire placard during PDI.



Ride, handling and road noise concerns may be caused by improperly adjusted tire pressure.



The first step in the diagnosis of these concerns is to verify that the tires are inflated to the correct pressures. The recommended tire inflation



pressure is listed on the vehicle's tire placard. The tire placard is located on the driver's side front or rear door edge, center pillar, or the rear



compartment lid.



Tip



- Generally a 5.6掳C (10掳F) temperature increase will result in (is equivalent to) a 6.9 kPa (1 psi) tire pressure increase.



- The definition of a "cold" tire is one that has been sitting for at least 3 hours, or driven no more than 1.6 km (1 mi).



- On extremely cold days, if the vehicle has been outdoors, it may be necessary to compensate for the low external temperature by adding



additional air to the tire during PDI.



- During cold weather, the Tire Pressure Monitor (TPM) indicator light (a yellow horseshoe with an exclamation point) may illuminate. If this



indicator turns off after the tires warm up (reach operating temperature), the tire pressure should be reset to placard pressure at the cold



temperature.



- The TPM system will work correctly with nitrogen in tires.



- The TPM system is compatible with the GM Vehicle Care Tire Sealant but may not be with other commercially available sealants.



Important



- Do not use the tire pressure indicated on the tire itself as a guide.



- Always inspect and adjust the pressure when the tires are cold.



- Vehicles that have different pressures for the front and the rear need to be adjusted after tire rotation.



Improper tire inflation may result in any or all of the following conditions:



- Premature tire wear



2010 Cadillac Truck SRX FWD V6-3.0L Page 18



- Harsh ride



- Excessive road noise



- Poor handling



- Reduced fuel economy



- Low Tire Pressure Monitor (TPM) Light ON



- Low Tire Pressure Message on the Drivers Information Center (DIC)
