DTC B1441 01

- Device Ignition OFF, RUN, and CRANK Circuit Short to Battery

DTC B1441 06

- Device Ignition OFF, RUN, and CRANK Circuit Short to Ground or Open

Diagnostic Fault Information

Circuit/System Description

This vehicles power mode master (PMM) is the body control module (BCM). The ignition switch is a low current switch with multiple discrete

ignition switch signals to the PMM for determination of the power mode. The PMM receives the ignition switch signals, and additionally a

reference voltage signal from the BCM, through the ignition switch, and back to the BCM. There are redundancies within the PMM system that can

allow operation of certain subsystems when there are faults in the ignition switch circuits. Other information such as serial data input from other

modules and DTCs is also used to determine what power mode signals and information is transmitted by the PMM. The BCM logic uses all this

information to identify the operators desired power mode and activate specific discrete signals, and serial data messages for the operation of many

different subsystems as necessary. Other modules which have switched voltage inputs may operate in a default mode if the PMM serial data

message does not match what the individual module can see from its own connections.

The PMM will activate relays and other direct outputs of the PMM as needed according to the calculated power mode. Several relays controlled by

the BCM are switched ignition voltage outputs the are pass through circuits within the BCM directly from the ignition switch. If these circuits short

to ground, the fuse to the ignition switch will open.

Conditions for Running the DTC

Ignition switch is in the START position.

Conditions for Setting the DTC

B1441 01

Off/run/crank voltage circuit is shorted to voltage for more than 2 seconds.

B1441 06

Off/run/crank voltage circuit is open for more than 2 seconds.

Action Taken When the DTC Sets

* The BCM operates in a fail-safe power mode dependent on the last valid power mode detected and the state of the engine run flag data on the

GMLAN serial data communications circuits.

* The other modules on the vehicle operate in a fail-safe power mode dependent on the last valid power mode transmitted by the BCM and the

state of the engine run flag on the GMLAN serial data communications circuits.

Conditions for Clearing the DTC

* A current DTC clears when the malfunction is no longer present.

* A history DTC clears when the module ignition cycle counter reaches the reset threshold of 50, without a repeat of the malfunction.

Diagnostic Aids

* A short to ground in the accessory wakeup serial data circuit will cause an open fuse to the ignition switch. DTC U1814 should be current.

* A short to ground in the run/crank ignition 1 voltage circuit of the run crank relay will cause an open fuse to the ignition switch. DTC B1428

should be current.

* The power modes and controls are determined using BCM logic. Comparing the Body Control Module Power Mode data display parameters

listed in Circuit/System Verification will determine if there is a power mode fault.

DTC P069E

- Fuel Pump Control Module Requested MIL Illumination

Circuit/System Description

The fuel pump control module uses the serial data network to signal the engine control module (ECM) that the fuel pump control module is

requesting malfunction indicator lamp (MIL) illumination. A DTC is set in the fuel pump control module, and the request for MIL illumination is

sent when the fuel pump control module determines that a failure that affects emissions has occurred in the fuel pump control system. When the

ECM receives the message from the fuel pump control module, DTC P069E will set in the ECM.

Conditions for Running the DTC

The ignition is ON, or the engine is running.

Conditions for Setting the DTC

The fuel pump control module requests the ECM to illuminate the MIL.

Action Taken When the DTC Sets

* DTC P069E is a Type A DTC.

* DTC P069E will continue to be current or active as long as the fuel pump control module is requesting MIL illumination.

DTC U2142 00

- Lost Communication With Yaw Rate Sensor (YRS)

Circuit/System Description

Modules connected to the CAN bus serial data circuits monitor for serial data communications during normal vehicle operation. Operating

information and commands are exchanged among the modules. The modules have prerecorded information about what messages are needed to be

exchanged on the serial data circuits. The messages are supervised and also, some periodic messages are used by the receiver module as an

availability indication of the transmitter module. Each message contains the identification number of the transmitter module.

The electronic brake control module (EBCM) activates the other modules connected to the CAN serial data circuits by applying voltage when the

ignition key is in ACC, ON or START. The EBCM, Yaw Rate and Lateral Acceleration Sensor are the only modules connected to the CAN bus

serial data circuits. For more information on CAN bus serial data refer to Data Link Communications Description and Operation (See: Powertrain

Management/Computers and Control Systems/Information Bus/Description and Operation).

Conditions for Running the DTC

* The system voltage is between 9-16 volts.

* The vehicle power mode master requires serial data communication to occur.

Conditions for Setting the DTC

A supervised periodic message that includes the transmitter module availability has not been received.

Action Taken When the DTC Sets

* The vehicle stability enhancement system (VSES), if equipped, and traction control system (TCS) will not function.

* System OFF lamps will illuminate for these systems.

Conditions for Clearing the DTC

* A current DTC clears when the malfunction is no longer present.

* A history DTC clears when the module ignition cycle counter reaches the reset threshold of 50, without a repeat of the malfunction.

Diagnostic Aids

* Sometimes, while diagnosing a specific customer concern or after a repair, you may notice a history U-code present. However, there is no

associated "current" or "active" status. Loss-of- communication U-codes such as these can set for a variety of reasons. Many times, they are

transparent to the vehicle operator and technician, and/or have no associated symptoms. Eventually, they will erase themselves automatically

after a number of fault-free ignition cycles. This condition would most likely be attributed to one of these scenarios:

- A control module on the data communication circuit was disconnected while the communication circuit is awake.

- Power to one or more modules was interrupted during diagnosis.

- A low battery condition was present, so some control modules stop communicating when battery voltage drops below a certain threshold.

- Battery power was restored to the vehicle and control modules on the communication circuit did not all re-initialize at the same time.

- If a loss-of-communication U-code appears in history for no apparent reason, it is most likely associated with one of the scenarios above.

These are all temporary conditions and should never be interpreted as an intermittent fault, causing you to replace a part.

* A control module may have a U-code stored in history that does not require any repairs. Issues with late or corrupted messages between

control modules can be temporary with no apparent symptom or complaint; this does not mean the control module is faulty. Do not replace a

control module based only on a history U-code.

* Do not replace a control module reporting a U-code. The U-code identifies which control module needs to be diagnosed for a communication

issue.

* Communication may be available between the BCM and the scan tool with either the low or high speed GMLAN serial data system

inoperative. This condition is due to the BCM using both the low and high speed GMLAN systems.

* Use to determine if the module uses high or low speed GMLAN serial data communications.

* Some control modules may not have internal protection for specific control circuits and may open a B+ or ignition fuse. If a fuse is open and

the B+ or ignition circuit is not shorted to ground, ensure none of the control circuits are shorted to ground before replacing the control

module.

* This diagnostic can be used for any control module that is not communicating, regardless of the type of serial data circuit it is connected to,

providing the vehicle is equipped with the control module.

DTC P0010

- Camshaft Position (CMP) Actuator Solenoid Control Circuit

Diagnostic Fault Information

Circuit/System Description

The camshaft position (CMP) actuator system enables the engine control module (ECM) to change the timing of the camshaft while the engine is

operating. The ECM controls the Camshaft Position Actuator Magnet duty cycle by controlling the amount of ON time. The magnet controls the

amount of engine oil flow to the CMP actuator by extending a pintle within the solenoid. The pintle acts against a spool valve in the CMP actuator

mechanism which is attached to the front of the camshaft. As the spool valve is moved, oil is directed to the CMP actuator, which rotates the

camshaft. The ECM can only command the camshaft position actuator to retard the valve timing from the camshaft park position, or advance the

valve timing back to the park position. The total range of valve timing command is 26 degree as measured at the camshaft or 52 degree as measured

at the crankshaft.

The ECM controls the Camshaft Position Actuator Magnet by suppling a 12 V pulse width modulated (PWM) signal. The ECM supplies a ground

to the low reference circuit.

Conditions for Running the DTC

* The ignition switch is in the crank or run position.

* The system voltage is between 11-18 V.

* The CMP actuator is command ON.

* DTC P0010 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

* DTC P0010 is a Type B DTC.

* The camshaft position actuator is commanded to the park position.

Conditions for Clearing the DTC

DTC P0010 is a Type B DTC.

Diagnostic Fault Information

Circuit/System Description

The drive motor generator position sensor is monitored by the motor control module (MCM). The MCM monitors the angular position, speed and

direction of the drive motor generator based upon the signals of the resolver-type position sensor. The position sensor, or resolver, contains a drive

coil, two driven coils and an irregular shaped metallic rotor. The metallic rotor is mechanically attached to the shaft of the drive motor generator. At

ignition ON, the MCM outputs a 7 volt ac, 10 kHz excitation signal to the drive coil. The drive coil excitation signal creates a magnetic field

surrounding the two driven coils and the irregular shaped rotor. The MCM then monitors the two driven coil circuits for a return signal. The

position of the irregular metallic rotor causes the magnetically-induced return signals of the driven coils to vary in size and shape. A comparison of

the two driven coil signals allows the MCM to determine the exact position, speed and direction of the drive motor generator.

Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC
