DTC 07

Solenoid Schematic:

Diagnostic Trouble Code (DTC) 7, Shorted Isolation Solenoid Or Electronic Brake Control Module (EBCM) Malfunction:

CIRCUIT DESCRIPTION
A Diagnostic Trouble Code (DTC) 7 sets when the Electronic Brake Control Module (EBCM) detects a short in the isolation valve solenoid or circuit. With the isolation valve shorted the EBCM cannot provide any of the pressure control functions. The short can be located in the Antilock Pressure Valve (APV), EBCM, or circuit between them.

TEST DESCRIPTION
Check the EBCM's internal circuitry for the isolation valve solenoid.
- Check the resistance of the isolation solenoid winding.
- Check if the connector repair corrected the condition.
- Check for a short to ground in the APV.

DIAGNOSTIC AIDS

CAUTION: Do not pierce the electrical connectors, wires, seals, or insulation during testing. Doing so will break the seal and lead to corrosion and failure of the wiring and terminals.
