1. DTC C003A[01] description
The wheel speed sensor converts the tire rotation into a pulse signal. The EHCU calculates the wheel speed according to the pulse signal from the wheel speed sensor. If the EHCU detects an abnormally low or high voltage in the rear left wheel speed sensor circuit, this DTC is set.
2. Condition for setting DTC C003A[01]
Condition for running the DTC
- The ignition switch is ON.
- The EHCU ignition power supply voltage is 10 to 16 V.
Condition for setting the DTC
- The EHCU detects a malfunction in the rear left wheel speed sensor circuit.
3. Action taken when DTC C003A[01] sets
- ABS warning light illumination
- ESC warning light illumination (Models equipped with ESC)
- ABS control inhibition
- TCS control inhibition (Models equipped with ESC)
- If a malfunction occurs during the EBD control, the control is continued. However, the control is inhibited except during the EBD control.
- ESC control inhibition (Models equipped with ESC)
- HSA control inhibition (Models with ESC)
- ISS control inhibition (Models with ESC)
- Hill Descent Control inhibition (Models with ESC)
- Brake Assist control inhibition (Models with ESC)
- ESS control inhibition (Models with ESC)
- Trailer sway control inhibition (Models equipped with ESC)
- External braking request brake retention control inhibition (Models equipped with stereo cameras)
- External braking request brake pressurization control inhibition (Models equipped with stereo cameras)
