Component Testing

1. Remove the intake manifold and disconnect the appropriate fuel injector.

2. Verify the resistance of each fuel injector with one of the following methods:

* If the engine coolant temperature (ECT) sensor is between 10-32掳C (50-90掳F), the resistance of each fuel injector should be 1.25-1.75

ohm.

瀚慖f not within the specified range, replace the fuel injector.

* If the ECT sensor is not between 10-32掳C (50-90掳F), measure and record the resistance of each fuel injector with a DMM. Subtract the

lowest resistance value from the highest resistance value. The difference between the lowest value and the highest value should be equal

to or less than 0.45 ohm.

瀚慖f the difference is more than 0.45 ohm, add all of the fuel injector resistance values to obtain a total resistance value. Divide the total

resistance value by the number of fuel injectors to obtain an average resistance value. Subtract the lowest individual fuel injector

resistance value from the average resistance value. Compute the difference between the highest individual fuel injector resistance

value and the average resistance value. Replace the fuel injector that displays the greatest difference above or below the average.

Diagnostic Fault Information

Circuit Description

The heated oxygen sensors (HO2S) are used for fuel control and catalyst monitoring. Each HO2S compares the oxygen content of the surrounding

air with the oxygen content of the exhaust stream. When the engine is started, the control module operates in an Open Loop mode, ignoring the

HO2S signal voltage while calculating the air-to-fuel ratio. The control module supplies the HO2S with a reference, or bias voltage of about 450

mV. While the engine runs, the HO2S heats up and begins to generate a voltage within a range of 0-1,000 mV. This voltage will fluctuate above

and below the bias voltage. Once sufficient HO2S voltage fluctuation is observed by the control module, Closed Loop is entered. The control

module uses the HO2S voltage to determine the air-to-fuel ratio. An HO2S voltage that increases above bias voltage toward 1,000 mV indicates a

rich fuel mixture. An HO2S voltage that decreases below bias voltage toward 0 mV indicates a lean fuel mixture.

The heating elements inside each HO2S heat the sensor to bring the sensor up to operating conditions faster. This allows the system to enter Closed

Loop earlier and the control module to calculate the air-to-fuel ratio sooner.

Circuit/System Description

Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding

air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. A heating

element inside the HO2S minimizes the time required for the sensors to reach operating temperature. Voltage is provided to the heater by an

ignition voltage circuit through a fuse. With the engine running, ground is provided to the heater by the HO2S heater low control circuit through a

low side driver within the engine control module (ECM). The ECM uses pulse width modulation (PWM) to control the HO2S heater operation to

maintain a specific HO2S operating temperature range.

- RR Side Impact Sensor Internal Electronic Failure

DTC B0088 3A

- RR Side Impact Sensor Incorrect Component Installed

Diagnostic Fault Information

Circuit/System Description

The inflatable restraint discriminating sensors utilizes a bidirectional 2-wire circuit. The sensor modulates current on the interface to send ID, state

of health, and deployment commands to the inflatable restraint sensing and diagnostic module (SDM). The SDM serves as a power source and a

ground for each of the sensors. When the ignition is turned ON and input power from the SDM is first detected, each sensor responds by

performing internal diagnostics and sending an ID to the SDM. The SDM considers the ID to be valid if the response time is less than 5 seconds.

The sensors continually communicates status messages to the SDM, which determines if a fault is present in the sensor or circuit. When a fault is

detected, the SDM may reset the appropriate sensor up to 2 times by removing and reapplying power to it. If the fault is still present, the SDM will

set a DTC.

Conditions for Running the DTC

Ignition voltage is between 9-16 V.

Conditions for Setting the DTC

All of the following conditions exist for 2.5 seconds:

Circuit/System Description

The HVAC control module controls the HVAC door actuators to regulate the airflow through the HVAC system. Each actuator consists of an

electric motor and a potentiometer. The module supplies a low reference and 5-volt reference source voltage to the potentiometer. The HVAC

control module monitors the voltage drop across the potentiometer on the door position signal circuit. When the actuator shaft rotates, the voltage

on the door position signal circuit changes. The HVAC module controls the direction of the actuator door by changing the polarity of the control

circuits.

* Air Flow Control 3 is the mode actuator

* Air Flow Control 7 is the recirculation actuator

* Temperature Control 1 is the left temperature actuator

* Temperature Control 2 is the right temperature actuator

Conditions for Running the DTC

* Ignition ON.

* Ignition voltage is between 9-16 volts.

* The HVAC module is ON.

Conditions for Setting the DTC

The actual door position differs from the commanded door position by more than 4 counts or the HVAC control module detects the door position

signal circuit is less than 7 counts or greater than 250 counts.

Action Taken When the DTC Sets

Control A and control B circuits are deactivated for the appropriate actuator.

Conditions for Clearing the DTC

* The DTC becomes history when the HVAC control module no longer detects the condition that set the DTC.

* The history DTC will clear after 50 fault-free ignition cycles.

Diagnostic Aids

* If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the scan tool Circuit

Test Status parameters for the component. The circuit status parameters change from OK or Not Run to Fault if there is a condition with the

circuit or a connection.

* An open fuse in the HO2S heater circuit may be caused by the heater element in one of the sensors. The condition may not be present until

the sensor operates for a period of time. If no fault is present in the heater circuit, monitor the amperage of each heater using the DMM to

determine if one of the heater elements is the cause of the open fuse. Inspect the sensor pigtail or the harness for contacting the exhaust

system.

DTC Descriptor

DTC B3055 00

- No Transponder Modulation or No Transponder

Circuit/System Description

When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is

energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value,

which is received by the theft deterrent module (TDM). The TDM then compares this value to a value stored in memory. This stored value is the

learned key code. If the value is correct, the TDM will send the prerelease password via the serial data circuit to the engine control module (ECM).

If the learned key code does not match or a transponder value is not received, the TDM will send the start disable password to the ECM.

Conditions for Running the DTC

Ignition is in the Accessory or Run position.

Conditions for Setting the DTC

The TDM is unable to measure the ignition key transponder value.

Action Taken When the DTC Sets

* Vehicle starting will be disabled.

* The security indicator will be illuminated.

Conditions for Clearing the DTC

* A current DTC will be cleared when the TDM detects a valid transponder value from the ignition key.

* A history DTC will be cleared after 100 malfunction-free ignition cycles or when a scan tool is used to clear DTCs.
