Circuit Description

The isolation and prime 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 C0141 Left Front TCS Solenoid 1 Circuit Malfunction
    • DTC C0146 Left Front TCS Solenoid 2 Circuit Malfunction
    • DTC C0151 Right Front TCS Solenoid 1 Circuit Malfunction
    • DTC C0156 Right Front TCS Solenoid 2 Circuit Malfunction

Conditions for Running the DTC
    • The ignition switch is in the ON position.
    • The DTC can be set after system initialization.

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/traction control system (TCS)/DRP for the duration of the ignition cycle.
    • A malfunction DTC is set.
    • The ANTI-LOCK indicator turns ON.
    • The TRAC Off indicator turns ON.
    • The red BRAKE Warning indicator could turn ON.

Conditions for Clearing the DTC
    • Condition for DTC is no longer present and scan tool clear DTC function is used.
    • 100 ignition cycles pass with no DTCs detected.

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 DLC.
  3. Carefully drive the vehicle above 12 km/h (8 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, check for DTCs.

Did any one of the DTCs C0141-C0151 reset as a current DTC?
