Diagnostic Fault Information

2010 Cadillac Truck SRX FWD V6-3.0L Page 1888

2010 Cadillac Truck SRX FWD V6-3.0L Page 1888

Circuit/System Description

The engine control module (ECM) controls the throttle valve by applying a varying voltage to the control circuits of the throttle actuator control

(TAC) motor. The ECM monitors the duty cycle that is required to actuate the throttle valve. The ECM monitors the throttle position sensors 1 and

2 to determine the actual throttle valve position.

Conditions for Running the DTC

* The vehicle speed is 0 km/h (0 mph).

* The engine speed is less than 40 RPM.

* The engine coolant temperature (ECT) is between 5-100掳C (41-212掳F).

* The intake air temperature (IAT) is between 5-143掳C (41-290掳F).

* The ignition voltage is greater than 10 volts.

* The accelerator pedal position (APP) is less than 15 percent.

* DTC P1551 runs when the conditions above have been met for greater than 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.

1. Ignition ON, observe the DTC information with a scan tool. DTC P0641, P0651, P0697, or P06A3 should not set.

2. Observe the appropriate scan tool 5 V Reference Circuit Test Status parameter. The parameter should display OK or Not Run.

3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

Note: Additional DTCs will set when disconnecting the components.

1. Ignition OFF, disconnect the harness connector of all appropriate sensors for the applicable DTC. Refer to Diagnostic Aids.

2. Ignition ON, test for 4.8-5.2 V between each of the affected 5 V reference circuits and ground.

瀚慖f the voltage is less than the specified range, test for a short to ground or for an open between the ECM and the affected circuit splice. If

the circuit tests normal, replace the K20 ECM.

瀚慖f the voltage is greater than the specified range, test for a short to voltage on the 5 V reference circuit. If the circuit tests normal, replace

the K20 ECM.

Note: A short to voltage on the signal circuit of certain components may cause this DTC to set.

3. Connect each component associated with the affected 5 V reference circuit one at a time while monitoring the appropriate scan tool 5 V

Reference Circuit Status parameter. The parameter should continue to display OK.

瀚慖f the parameter displays Fault when a component is connected, test the signal circuit of that component for a short to voltage. If the

circuit tests normal, replace the component.

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.

Diagnostic Fault Information

Circuit/System Description

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.
