CIRCUIT DESCRIPTION
The electronic brake control relay supplies power to the solenoid valves and pump motor. The electronic brake control relay, located in the EBCM/EBTCM, is activated whenever the ignition switch is in the RUN position and no faults are present. The electronic brake control relay remains engaged until the ignition switch is turned off or a failure is detected.

CONDITIONS FOR SETTING THE DTC
DTC C1214 will set anytime the electronic brake control relay is commanded on and the solenoid valve relay voltage is less than 8 volts, and ignition voltage is greater than 10.5 volts.

ACTION TAKEN WHEN THE DTC SETS
^ A malfunction DTC is stored.
^ ABS/TCS is disabled.
^ 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 have passed with no DTCs detected.

DIAGNOSTIC AIDS
^ Possible causes for DTC C1214 to set are:
- Poor battery conditions or connections.
- Poor engine ground connections.
- Poor EBTCM connector/terminal matings.

^ It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
^ If an intermittent malfunction exists refer to Intermittents and Poor Connections Diagnosis in Diagnostic Aids.
^ The electronic brake control relay is integral to the EBCM/EBTCM and is not serviceable separately.
