| Diagnostic Codes |
| Code | Name | Description | Action Required |
|---|
| 12 | No ABS Fault codes Stored | System OK (as far as self test can determine) | |
| 10 | Separator Code | This code is displayed between Fault Codes | |
| 11 | The ABS System is OK | There are no registered faults with the ABS Module | |
| 17 | Hydraulic Solenoid | The Solenoid is continuously powered up | Check the Relay and wiring for possible shorts to Battery +12V |
| 18 | ABS ECM Fault | The ABS Module may not be getting power, or ground | Check to see if the ECM is getting +12V, and that the battery ground strap is connected |
| 29 | Hydraulic Actuator | The Hydraulic Actuator Appears to be not connected | Check the wiring loom for any loose connections, or damage to the wiring |
| 31 | ABS Warning Lamp | The Check ABS Warning Lamp appears to not be functioning correctly | Check the globe to see if it is blown, if the bulb holder is sitting correctly, and that the ABS Fuse is not blown |
| 32 | Hydraulic Solenoid Voltage Monitor | The Voltage is low, or the circuit is open or shorted | Check the Electrical connections for good contact, Check the Battery Voltage at the Solenoid |
| 33 | Warning Lamp Diode | There is a problem with the warning Lamp diode, located on the Back of the Cluster wiring loom | Check to see if the Diode is fitted, and the wiring has not been damaged |
| 34 | Excessive Speed Sensor Signal Decay | The sensor signal is wrong for the current vehicle conditions. The fault could be in the sensor, the wiring, or the ECU. The tone wheel may be missing, or the wrong type fitted. The Sensor may have fallen out. | Check the Brake Lines, Test Speed sensor, and wiring loom for speed sensor. (Vehicle may have been braked on ice or snow, or driver performed a line lock burnout |
| 35 | ABS Pump Motor | The Pump Motor appears to be not working, or is permanently on | Check the Pump Relay for a short, open circuit, voltage at the pump, and wiring connectors |
| 36 | Brake Decay Extended | The Speed Sender count does not match the wheel speed | The Park brake may have been on while the vehicle driven, the ABS tone wheel may be damaged, the Brake is not able to decay pressure |
| 43 | Right Rear wheel speed sensor fault (Drivers Side) | The sensor signal is wrong for the current vehicle conditions. The fault could be in the sensor, the wiring, or the ECU. The tone wheel may be missing, or the wrong type fitted. The Sensor may have fallen out. | Test Speed sensor, the ABS Tone Wheel, and wiring loom for speed sensor. Also clean sensor and tone wheel |
| 44 | Left Rear wheel speed sensor fault (Passenger Side) | The sensor signal is wrong for the current vehicle conditions. The fault could be in the sensor, the wiring, or the ECU. The tone wheel may be missing, or the wrong type fitted. The Sensor may have fallen out. | Test Speed sensor, the ABS Tone Wheel, and wiring loom for speed sensor. Also clean sensor and tone wheel |
| 45 | Right Front wheel speed sensor fault (Drivers Side) | The sensor signal is wrong for the current vehicle conditions. The fault could be in the sensor, the wiring, or the ECU. The tone wheel may be missing, or the wrong type fitted. The Sensor may have fallen out. | Test Speed sensor, the ABS Tone Wheel, and wiring loom for speed sensor. Also clean sensor and tone wheel |
| 46 | Left Front wheel speed sensor fault (Passenger Side) | The sensor signal is wrong for the current vehicle conditions. The fault could be in the sensor, the wiring, or the ECU. The tone wheel may be missing, or the wrong type fitted. The Sensor may have fallen out. | Test Speed sensor, the ABS Tone Wheel, and wiring loom for speed sensor. Also clean sensor and tone wheel |
| 47 | Average wheel speed sensor fault (Drivers Side) | One wheel has wheel spin for 3 to 8 seconds after key ON, Two wheels have wheel spin for more than 20 seconds after key ON | Test Speed sensor, the ABS Tone Wheel, and wiring loom for speed sensor. Also clean sensor and tone wheel |
| 71 | Right Rear Wheel Speed Sensor | There is a continuity fault with the wiring for the Wheel sensor - (No Signal) | Check the wiring harness for the wheel sensor is connected, and not shorted or open circuit |
| 72 | Left Rear Wheel Speed Sensor | There is a continuity fault with the wiring for the Wheel sensor - (No Signal) | Check the wiring harness for the wheel sensor is connected, and not shorted or open circuit |
| 73 | Right Front Wheel Speed Sensor | There is a continuity fault with the wiring for the Wheel sensor - (No Signal) | Check the wiring harness for the wheel sensor is connected, and not shorted or open circuit |
| 74 | Left Front Wheel Speed Sensor | There is a continuity fault with the wiring for the Wheel sensor - (No Signal) | Check the wiring harness for the wheel sensor is connected, and not shorted or open circuit |
| 90 | ABS Model ID | This code does not indicate an ABS Fault | |
