PINPOINT TEST E: DTC C114:, (RF), DTC C1155 (LF), DTC C1165 (RR), DTC C1175 (LR)-WHEEL SPEED SENSOR INPUT CIRCUIT FAILURE

CAUTION: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.

Normal Operation
The wheel speed sensor and sensor ring generate a square wave signal to the ABS module that is proportional to wheel speed. The ABS module compares wheel speed inputs from all wheel speed sensors to determine an impending wheel lockup.

Possible Causes
^ Mismatched tire sizes.
^ Wheel speed sensor ring.
^ Wheel speed sensor.
^ ABS module.
