DTC Descriptor

DTC C0292 1A

Multi-Axis Acceleration Sensor Module Circuit Performance - Bias Level Out of Range

Diagnostic Fault Information

Circuit/System Description

The Lateral Acceleration sensor, the Longinitudinal Acceleration Sensor and the Yaw Rate Sensors are combined into one sensor called the Multi-axis Acceleration Sensor, which is internal to the inflatable restraint sensing and diagnostic module. The Multi-axis Acceleration Sensor communicates with the Electronic Brake Control Module via serial data. The module activates the stability control function depending on Multi-axis Acceleration Sensor input.

Conditions for Running the DTC

• Ignition ON.
• Ignition voltage is greater than 8 V.

Conditions for Setting the DTC

A short to ground or an open/high resistance is detected on the ignition circuit.

Action Taken When the DTC Sets

• The air bag indicator turns ON
• The traction/stability control indicator turns ON
• A message may be displayed on the driver information center.
• The electric brake control module disables the electronic stability control and the hill start assist for the duration of the ignition cycle.

Conditions for Clearing the DTC

• The condition for setting the DTC is no longer present.
• The history DTC will clear after 40 consecutive fault-free ignition cycles have occurred.

Circuit/System Testing

1. Ignition OFF, scan tool disconnected, and all vehicle systems OFF, disconnect the X1 and X2 harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module. It may take up to 2 minutes for all vehicle systems to power down.
2. Test for less than 25 ohms between the ground circuit terminal 19 and ground.

If 25 ohms or greater

1. Ignition OFF.
2. Test for less than 2 ohms in the ground circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, repair the open/high resistance in the ground connection.

If less than 25 ohms

3. Ignition ON.
4. Verify that a test lamp illuminates between the ignition circuit terminal 17 and ground.

If the test lamp does not illuminate and the circuit fuse is good

1. Ignition OFF, remove the test lamp.
2. Test for less than 2 ohms in the ignition circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, verify the fuse is OK and there is voltage at the fuse.

If the test lamp does not illuminate and the circuit fuse is open

1. Ignition OFF, remove the test lamp.
2. Test for infinite resistance between the ignition circuit and ground.

• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance, replace the K36 Inflatable Restraint Sensing and Diagnostic Module.

If the test lamp illuminates

5. Replace the K36 Inflatable Restraint Sensing and Diagnostic Module.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.
