Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pinpoint Test Ag: RCM (Restraints Control Module) Data Concern
Normal Operation and Fault Conditions
The ABS module receives vehicle yaw rate, lateral acceleration, longitudinal acceleration and roll rate from RCM over the HS-CAN2. The yaw rate sensor, lateral accelerometer, longitudinal accelerometer and roll rate sensor are all contained in the RCM. A failure of the HS-CAN2, an internal failure of the RCM or the internal sensors causes the ABS module to set one or more Diagnostic Trouble Codes (DTCs).
REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS C0061:28 | Lateral Acceleration Sensor: Signal Bias Level Out Of Range/Zero Adjustment Failure | Sets if the absolute value of the longitudinal acceleration message from the RCM is outside of the maximum allowable range. |
| ABS C0061:64 | Lateral Acceleration Sensor: Signal Plausibility Failure | The ABS module creates a reference value based on all other available sensor signals and compares this value. If the 2 values differ by more than the predetermined value, this DTC is set. |
| ABS C0062:64 | Longitudinal Acceleration Sensor: Signal Plausibility Failure | Sets if the sensor signal does not match the other stability sensor signals (steering angle, yaw rate, longitudinal acceleration or lateral acceleration). |
| ABS C0063:28 | Yaw Rate Sensor: Signal Bias Level Out Of Range/Zero Adjustment Failure | Sets if the absolute value of the longitudinal acceleration message from the RCM is outside of the maximum allowable range. |
| ABS C0063:64 | Yaw Rate Sensor: Signal Plausibility Failure | Sets if the sensor signal does not match the other stability sensor signals (steering angle, yaw rate, longitudinal acceleration or lateral acceleration). |
| ABS C0064:28 | Roll Rate Sensor: Signal Bias Level Out Of Range/Zero Adjustment Failure | Sets if the sensor signal does not match the other stability sensor signals (steering angle, yaw rate, longitudinal acceleration or lateral acceleration). |
| ABS C0064:64 | Roll Rate Sensor: Signal Plausibility Failure | Sets if the sensor signal does not match the other stability sensor signals (steering angle, yaw rate, longitudinal acceleration or lateral acceleration). |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
