ANTI-LOCK BRAKE SYSTEM MODULE DIAGNOSTIC TROUBLE CODE INDEX
| DTC | Description | Source | Action |
|---|---|---|---|
| B1317 | Battery Voltage High | ABS Module | GO to PINPOINT TEST G . |
| B1318 | Battery Voltage Low | ABS Module | GO to PINPOINT TEST G . |
| B1342 | ECU is Defective | ABS Module |
NOTE:
If other DTCs are present, REPAIR them before installing a new component. CLEAR the DTCs. RETRIEVE the DTCs. If DTC B1342 is retrieved again, INSTALL a new module. REFER to HYDRAULIC CONTROL UNIT (HCU) . REPEAT the self-test. |
| B2477 | Module Configuration Failure | ABS Module | REFER to MODULE CONFIGURATION . |
| B2741 | Sensor Cluster Defective | ABS Module | INSTALL a new sensor cluster. REFER to ACCELEROMETER - HYBRID . FOLLOW the diagnostic tool directions for the calibration procedure. |
| B2900 | VIN Mismatched | ABS Module | VERIFY the module has the correct as-built data. REFER to MODULE CONFIGURATION . CHECK for correct powertrain control module (PCM) and ABS module configuration using the diagnostic tool. RECONFIGURE the components as necessary. FOLLOW the diagnostic tool directions. CLEAR the DTCs. REPEAT the self-test. |
| C1095 | ABS Hydraulic Pump Motor Circuit Failure | ABS Module | Cycle the ignition switch. CLEAR the DTCs. With the ignition in the RUN position, fully press and release the brake pedal at least 10 times to activate the hydraulic pump motor. CARRY OUT the on-demand self test. Retrieve the DTCs. If DTC C1095 is present, INSTALL a new hydraulic control unit. REFER to HYDRAULIC CONTROL UNIT (HCU) - HYBRID . TEST the system for normal operation. |
