DTC C1232-C1235: Wheel Speed Circuit Open Or Shorted
- Ensure ignition switch is in LOCK position. Inspect suspect wheel speed sensor harness, sensor and sensor rotor for damage. Repair as needed. If all components are okay, go to next step.
- Test drive vehicle at various speeds and road surfaces. If DTC(s) resets, go to next step. If DTC(s) does not reset, DTC is intermittent. Inspect harness and connections for damage or corrosion. Repair as needed.
- Disconnect harness connector of suspect wheel speed sensor. Measure resistance between component terminals. If resistance is 800-1600 ohms, go to next step. If resistance is not 800-1600 ohms, replace wheel speed sensor and retest.
- Check continuity between ground and each terminal of suspect wheel speed sensor. If continuity does not exist, go to next step. If continuity does exist, replace speed sensor.
- Check continuity of circuits between ABS actuator harness connector and suspect wheel speed sensor harness connector. See WIRING DIAGRAMS . If continuity does not exist on either sensor circuit, repair open circuit as needed and retest. If continuity exists on both circuits, go to next step.
- Ensure suspect wheel speed sensor harness connector is disconnected. Measure voltage between ground and each terminal of wheel speed sensor on ABS actuator harness connector. See WIRING DIAGRAMS . If voltage is not present on either circuit, go to next step. If voltage is present, repair wheel speed sensor circuit for short to voltage.
- Check continuity between ground and suspect wheel speed sensor harness connector terminals. If continuity is present, repair suspect circuit for short to ground. If continuity is not present, replace ABS actuator assembly and retest system.
