Anti-Lock Brake System (ABS) and Stability Control — 2016 workshop reference 2987

module. Each wheel speed sensor is connected to the ABS module through 2 wires and a connector at each wheel speed sensor. One wire is for sensor voltage supply from the ABS and the other wire is for the signal return to the ABS. With the ignition ON, the ABS module carries out a self-test by sending a reference voltage through the wheel speed sensors and their circuitry.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
C0037:11	Left Rear Wheel Speed Sensor: Circuit Short to Ground	These Diagnostic Trouble Codes (DTCs) set in continuous memory and on-demand if there is a short to ground in the sensor signal return circuit or if the sensor has an internal short to ground.
C003A:11	Right Rear Wheel Speed Sensor: Circuit Short to Ground
C0037:15	Left Rear Wheel Speed Sensor: Circuit Short to Battery or Open	These Diagnostic Trouble Codes (DTCs) set in continuous memory and on-demand if there is a short to battery voltage or an open in the sensor signal return circuit. A short to battery voltage may be due to the sensor signal return circuit and the sensor voltage supply circuit shorted together. These Diagnostic Trouble Codes (DTCs) also set if the sensor has an internal short to battery voltage or an open circuit.
	C003A:15 Right Rear Wheel Speed Sensor: Circuit Short to Battery or Open

Possible Causes

Wiring, terminals or connectors Wheel speed sensors ABS module

Visual Inspection and Diagnostic Pre-checks

Make sure the wheel speed sensor harness is routed correctly and is undamaged. Make sure the wheel speed sensor electrical connector is free from any corrosion or other contaminants.

PINPOINT TEST L : WHEEL SPEED SENSOR ELECTRICAL FAULTS - REAR

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector

L1 CHECK FOR FAULT REPEATABILITY

Ignition ON. Using a diagnostic scan tool, clear all ABS module Diagnostic Trouble Codes (DTCs). Ignition OFF. Ignition ON. Test drive the vehicle above 20 km/h (12 mph) and carry out at least 1 ABS stop. Bring the vehicle to a safe stop. Using a diagnostic scan tool, carry out the ABS module self-test.

Is DTC C0037:11, C0037:15, C003A:11 or C003A:15 present?

Yes If the Rotunda Active Wheel Speed Sensor Tester is available, GO to L2

If the Rotunda Active Wheel Speed Sensor Tester is not available and DTC C0037:15 or C003A:15 is present, GO to L5 If the Rotunda Active Wheel Speed Sensor Tester is not available and DTC C0037:11 or
