Test E: DTC C1145, DTC C1155, DTC C1165, DTC C1175 - Wheel Speed Sensor Input Circuit Failure
Test E: DTC C1145, DTC C1155, DTC C1165, DTC C1175 - Wheel Speed Sensor Input Circuit FailureNormal Operation
The active wheel speed sensor generates a signal that is sent to the anti-lock brake system (ABS) module. The wheel speed sensor circuitry connects to the ABS module connector C155 through 2 wires and a connector at each wheel speed sensor. When the ignition switch is turned to the RUN position, the ABS module carries out a self-test by sending a reference voltage through the right front wheel speed sensor and its circuitry to determine if they are functional.
Voltage is supplied to the active wheel speed sensors from the ABS module. The wheel speed sensor ground is supplied by the ABS module.
Possible Causes
^ Circuit open
^ Circuit shorted
^ Wheel speed sensor
^ ABS module
CAUTION: Use the flex probe kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.
