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.
The DTC can set anytime the ignition switch is in the ON position.
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. |
If equipped, the following actions occur:
• | The EBCM disables the antilock brake system (ABS), traction control system (TCS), and dynamic rear proportion (DRP) for the duration of the ignition cycle. |
• | A malfunction DTC will set. |
• | The ABS telltale turns ON. |
• | The condition for the DTC is no longer present. |
• | Using a scan tool, clear the DTC function. |
• | The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
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 | Did you perform the Diagnostic System Check? | Go to Step 2 | |
Did any one of the DTCs C0060-C0095 reset as a current DTC? | Go to Step 3 | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | |
3 | Replace the EBCM. Refer to Electronic Brake Control Module Replacement . Is the repair complete? | Go to Step 4 | -- |
