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.

Conditions for Running the DTC
The system voltage is between 9-16 V.
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
* Specific subsystems will not function.
* DTC U0100 in the TCM will cause the transmission to go into default gears.
* Both DTC U0100 in the TCM and DTC U0101 in the ECM will cause the malfunction indicator lamp (MIL) to illuminate.
Conditions for Clearing the DTC
* The ECM/TCM turns OFF the MIL after 4 consecutive ignition cycles that the diagnostic runs and does not fail.
* A current DTC clears when the malfunction is no longer present.
* A history DTC clears when the control 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

Diagnostic Aids
Note: Verify that the engine is in good mechanical condition before continuing with this diagnostic.
* A skewed or stuck engine coolant temperature (ECT) or IAT sensor will cause the calculated models to be inaccurate and may cause this
DTC to run when it should not. Refer to Temperature Versus Resistance (See: Powertrain Management/Computers and Control
Systems/Specifications/Temperature Versus Resistance).
* The BARO that is used by the ECM to calculate the air flow models is initially based on the MAP sensor at ignition ON. When the engine is
running, the ECM will continually update the BARO value near wide open throttle using the MAP sensor and a calculation. A skewed MAP
sensor will cause the BARO value to be inaccurate. Use the scan tool and compare the BARO parameter at ignition ON to the Altitude vs.
Barometric Pressure Table. Refer to Altitude Versus Barometric Pressure (See: Powertrain Management/Computers and Control
Systems/Specifications/Altitude Versus Barometric Pressure).
* A skewed MAP sensor will also cause the first and second intake manifold models to disagree with the actual MAP sensor measurements.
Use the scan tool and compare the MAP Sensor parameter to a known good vehicle, under various operating conditions.
* Inspect for worn piston rings. Refer to Engine Compression Test (See: Engine, Cooling and Exhaust/Engine/Compression Check/Testing

Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
B0012 01 Stage 1 or B0013 01 Stage 2
The driver steering wheel air bag high and/or low circuit is shorted to voltage for 120 milliseconds.
B0012 02 Stage 1 or B0013 02 Stage 2
The driver steering wheel air bag high and/or low circuit is shorted to ground for 120 milliseconds.
B0012 04 Stage 1 or B0013 04 Stage 2
The driver steering wheel air bag high and/or low circuit is open for 120 milliseconds.
B0012 0D Stage 1 or B0013 0D Stage 2
The driver steering wheel air bag deployment loop resistance is greater than 5.1 ohms for 120 milliseconds.
B0012 0E Stage 1 or B0013 0E Stage 2
The driver steering wheel air bag deployment loop resistance is less than 1.3 ohms for 120 milliseconds.
Action Taken When the DTC Sets
* The SDM requests the instrument panel cluster (IPC) to illuminate the AIR BAG indicator.
* The SDM will store a DTC, however if an event occurs the system will still attempt deployments.
Conditions for Clearing the DTC
* The condition for setting the DTC no longer exists.
* A history DTC will clear once 100 malfunction-free ignition cycles have occurred.
Diagnostic Aids
* When a harness connector is disconnected, the high control and low control circuits are shorted together by the integral shorting bar. This
should be taken into account when testing for faults on these circuits.
* This DTC usually indicates a poor connection or a wiring malfunction between the SDM and the deployment loop.
