C0147

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.

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:
^ A malfunction DTC is stored.
^ ABS/TCS is disabled.
^ The ABS/TCS indicators are turned 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 DTC(s) 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.
