DTC B1295 07

- Steering Wheel Controls Group 2 Signal Circuit High Voltage

Diagnostic Fault Information

Circuit/System Description

The body control module (BCM) supplies voltage to the steering wheel control switches and monitors the return signal. Each switch state is

associated to a set resistance value and when pressed a specific voltage drop occurs across the resistor unique to the switch. The BCM identifies the

switch selection and activates the feature.

Conditions for Running the DTC

* The system voltage is between 9-16 V.

* The ignition is ON.

Conditions for Setting the DTC

* The BCM detects a short to voltage on the signal circuit.

* The above condition is present for greater than 30 s.

Action Taken When the DTC Sets

The BCM will ignore switch inputs.

Conditions for Clearing the DTC

* The condition responsible for setting the DTC no longer exists.

* A history DTC will clear once 100 consecutive malfunction free ignition cycles have occurred.

Diagnostic Fault Information

Circuit/System Description

The OnStar(R) button assembly consists of 3 buttons, Call/Answer, OnStar(R) Call Center, and OnStar(R) Emergency. The telematics

communication interface control module supplies the OnStar(R) button assembly with 10 V via the keypad supply voltage circuit. Each of the

buttons, when pressed, completes the circuit across a resistor allowing a specific voltage to be returned to the telematics communication interface

control module over the keypad signal circuit. Depending upon the voltage range returned, the telematics communication interface control module

is able to identify which button has been activated.

Conditions for Running the DTC

* Ignition ON.

* Battery voltage must be between 9-16 V.

Conditions for Setting the DTC

- High Beam Request Signal Circuit Performance - Signal Invalid

Diagnostic Fault Information

Circuit/System Description

The BCM monitors the voltage level within the high beam signal circuit and the flash to pass signal circuit. When the turn signal/multifunction

switch is moved to the high beam position or to the flash to pass position, the voltage within the appropriate signal circuit drops to less than 1 V.

The BCM will detect the voltage drop and will command the headlamp high beams to turn ON or OFF.

Conditions for Running the DTC

Battery voltage must be between 9-16 V.

Conditions for Setting the DTC

The BCM detects a short to ground in the headlamp high beam signal circuit.

Action Taken When the DTC Sets

The high beam headlamps will malfunction.

Conditions for Clearing the DTC

* The DTC will be current for as long as the fault is present.

* When the fault is no longer present, the DTC will be a history DTC.

* A history DTC will clear after 50 ignition cycles.

DTC Descriptor

DTC B3060 00

- Unprogrammed Transponder Identification Code Received Malfunction

Circuit/System Description

When an ignition key is inserted into the ignition lock cylinder and the ignition mode is changed, 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 body control module (BCM). The BCM then compares this value to a value stored in memory. If the value is not correct,

the BCM disables engine start.

Conditions for Running the DTC

Ignition is in the Accessory or Run position.

Conditions for Setting the DTC

The transponder value measured by the BCM is incorrect or not learned to the vehicle.

Action Taken When the DTC Sets

* Vehicle starting will be disabled.

* The security indicator in the instrument cluster will be illuminated. The driver information center will display a service message.

Conditions for Clearing the DTC

* A current DTC will be cleared when the BCM 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.

DTC B302A 00

- Mobile Telephone Communications Interface Requested Immobilization Malfunction

Circuit/System Description

As part of the vehicle telematics enhanced services, a request may be sent to the body control module (BCM) to disable vehicle starting. If a valid

message is received by the BCM requesting that starting be disabled, the start enable message will not be sent to the engine control module (ECM).

Conditions for Running the DTC

The BCM continuously monitors for this DTC.

Conditions for Setting the DTC

A valid start disable from telematics will set DTC B302A only as a history DTC.

Action Taken When the DTC Sets

Vehicle starting will be suspended and the security indicator will be illuminated.

Conditions for Clearing the DTC

* A current DTC will clear when the telematic start disable request is no longer seen.

* A history DTC will clear after 100 ignition cycles in which the telematic start disable request is not seen.

Diagnostic Aids

DTC B302A is only an indicator that a start disable request has been received from the vehicle telematics system and does not indicate a fault in the

immobilizer system. DTC will only set as a history.

- Seat Heaters Common Circuit Short to Battery

DTC B242A 02

- Seat Heaters Common Circuit Short to Ground

Diagnostic Fault Information

Circuit/System Description

The rear seat heating control module controls seat heating operation for both left and right rear seats. The heating elements are controlled through

individual high side and low side control circuits. The low side control circuits for both seats are connected to a common reference point internal to

the module. This reference point is biased to approximately 2.5 V. Before the rear seat heating control module will allow heated seat operation, it

checks to see if this biased voltage is shorted to ground or voltage. Once the module verifies that it is not closing to a shorted heating element, it

allows for heated seat operation. The module will then continue to monitor the heating elements for a shorted circuit.

Conditions for Running the DTC

* DTC B1325 must not be present.

* The rear seat heating control module must be powered.

Conditions for Setting the DTC

B242A 01

The rear seat heating control module detects a short to voltage on the heater element control circuits

B242A 02

The rear seat heating control module detects a short to ground on the heater element control circuits.

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

B3794 08

The BCM detects an invalid voltage signal on the cruise control switch signal circuit for 1 second.

DTC B128D 62

- Video Display Position Signal Stuck Open

DTC B128D 63

- Video Display Position Signal Stuck Closed

Diagnostic Fault Information

Circuit/System Description

The radio controls the position of the Radio/Navigation Display via the position control circuit. When the UP position is desired, the radio sends a

voltage signal to the Radio/Navigation Display actuator on the position control circuit, which commands the Radio/Navigation Display actuator to

raise the display. When the display reaches the fully raised position, the actuator controller sends a voltage signal to the radio on the position signal

circuit. When commanded up and fully raised, the voltage values on the control and position signal circuits will typically be greater than 4 V.

To lower the display, the radio removes the voltage signal on the position control circuit, which commands the Radio/Navigation Display actuator

to lower the display. When the display reaches the fully lowered position, the actuator controller remove the voltage signal to the radio on the

position signal circuit. When commanded down and fully lowered, the voltage values on the control and position signal circuits will be less than 1

V.

The display automatically returns to the lowered position when the ignition is turned OFF. When the ignition is turned ON, the radio commands the

display to return to it's previous position, raised or lowered, that was commanded during the previous ignition cycle.

Conditions for Running the DTC

The radio is ON.
