DTC C1A95-64: Wheel Speed Sensor - Signal plausibility failure: Action
- Check for correct wheel/tire sizes. Check the wheel speed sensors and circuits for damage. Remove the sensor and visually inspect the sensor ring on the constant velocity joint for missing or damaged teeth. If the sensor ring is damaged, renew the constant velocity joint. Use an oscilloscope to examine the signals from all wheel speed sensors for abnormal high frequencies (modulation and peak signals). Renew sensors as necessary. After rectification, either clear the DTCs and cycle the ignition or cycle the ignition and drive the vehicle above 15kph for at least 30 seconds to ensure the lamps extinguish. When cycling the ignition, allow sufficient time for the 'P' symbol illumination to extinguish on the gear shifter (if installed) before returning the ignition state to on
