The inlet and outlet 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.
• | The DTC can set anytime the ignition switch is in the ON position. |
• | The DTC can set when the vehicle speed is greater then 6 km/h (4 mph) and the brake pedal is not applied. |
• | The DTC can set when the vehicle speed is greater then 15 km/h (9 mph) and the brake pedal is applied. |
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:
• | A malfunction DTC is stored. |
• | ABS/TCS is disabled. |
• | The ABS/TCS indicators are turned on. |
• | Condition for DTC is no longer present and scan tool clear DTC function is used. |
• | 100 ignition cycles pass with no DTC(s) detected. |
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? | ||
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 | -- |
