1. DTC C0037[14] 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. When the EHCU detects an open circuit or a short to ground in the rear right wheel speed sensor signal circuit, this DTC is set.
2. Condition for setting DTC C0037[14]
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
Any of the following are met:
- The EHCU detects an open circuit in the rear right wheel speed sensor signal circuit.
- The EHCU detects a short to ground in the rear right wheel speed sensor signal circuit.
3. Action taken when DTC C0037[14] sets
- ABS warning light illumination
- ESC warning light illumination (Models equipped with ESC)
- ABS control inhibition
