The isolation and prime 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 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.
