PPT J ABS MODULE DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U0126:00 | Lost Communication With Steering Angle Sensor Module: No Sub Type Information | Sets when the ABS module does not receive any steering angle sensor messages from the SASM. |
| U0428:41 | Invalid Data Received From Steering Angle Sensor Module: General Checksum Failure | The ABS module calculates the steering angle based on the wheel speed sensors and stores a checksum in memory. When the ABS module receives the steering angle message from the SASM, the checksum in memory is compared against the checksum received from the SASM. If the 2 checksums are not equal, this DTC is set. |
