C0156

DTC C0141-C0156
Circuit Description
The isolation and prime valve solenoid circuits are supplied with battery power when the ignition is in the ON position. The EBCM controls the valve functions by grounding the circuit when necessary.

DTC Descriptors
This diagnostic procedure supports these DTCs:
^ DTC C0141 Left Traction Control System (TCS) Solenoid/Motor (single or 1) Circuit
^ DTC C0146 Left Traction Control System (TCS) Solenoid/Motor 2 Circuit
^ DTC C0151 Right Traction Control System (TCS) Solenoid/Motor (single or 1) Circuit
^ DTC C0156 Right Traction Control System (TCS) Solenoid/Motor 2 Circuit

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 these conditions 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, these actions occur:
^ The electronic brake control module (EBCM) disables the antilock brake system (ABS)/traction control system (TCS)/vehicle stability enhancement system (VSES)/dynamic rear proportion (DRP) for the duration of the ignition cycle.
^ A malfunction DTC is set.
^ The ABS indicator turns ON.
^ The Stability 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.
