Circuit Description

The inlet and outlet valve solenoid circuits are supplied with battery power when the ignition is in the ON position. The electronic brake control module (EBCM) controls the valve functions by grounding the circuit when necessary.

DTC Descriptors

This diagnostic procedure supports the following DTCs:

    • DTC C0060 Left Front ABS Solenoid #1 Circuit Malfunction
    • DTC C0065 Left Front ABS Solenoid #2 Circuit Malfunction
    • DTC C0070 Right Front ABS Solenoid #1 Circuit Malfunction
    • DTC C0075 Right Front ABS Solenoid #2 Circuit Malfunction
    • DTC C0080 Left Rear ABS Solenoid #1 Circuit Malfunction
    • DTC C0085 Left Rear ABS Solenoid #2 Circuit Malfunction
    • DTC C0090 Right Rear ABS Solenoid #1 Circuit Malfunction
    • DTC C0095 Right Rear ABS Solenoid #2 Circuit Malfunction

Conditions for Running the DTC
    • The DTC can set anytime the ignition switch is in the ON position.
    • The DTC can set when the vehicle speed is greater than 15 km/h (9 mph).

Conditions for Setting the DTC

The DTC will set when the EBCM detects one of the following internal to the EBCM only:

    • An open in the solenoid coil or circuit.
    • A short to ground in the solenoid coil or circuit.
    • A short to voltage in the solenoid coil or circuit.

Action Taken When the DTC Sets

If equipped, the following actions occur:

    • The EBCM disables the ABS/TCS/DRP for the duration of the ignition cycle.
    • A malfunction DTC will set.
    • The ABS indicator turns ON.

Conditions for Clearing the DTC
    • The condition for the DTC is no longer present and you used the scan tool Clear DTC function.
    • The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Diagnostic Aids

The solenoid valve circuit and the solenoid coil are internal to the EBCM. No part of the solenoid circuit is diagnosable external to the EBCM. The DTC sets when there is a malfunction in the solenoid circuit internal to the EBCM only.

  1. Using a scan tool clear the DTC.
  2. Remove the scan tool from the data link connector.
  3. Carefully drive the vehicle above 15 km/h (9 mph) for several minutes.
  4. Turn the ignition switch to the OFF position.
  5. Install a scan tool.
  6. Turn the ignition switch to the ON position, engine off.
  7. Using the scan tool in Diagnostic Trouble Codes, retrieve current DTCs.

Did any one of the DTCs C0060-C0095 reset as a current DTC?
