DTC 08

Solenoid Schematic:

Diagnostic Trouble Code (DTC) 8, Shorted Dump Solenoid Or Electronic Brake Control Module (EBCM) Malfunction:

CIRCUIT DESCRIPTION
A Diagnostic Trouble Code (DTC) 8 sets when the Electronic Brake Control Module (EBCM) detects a short in the dump valve solenoid or circuit. Without the use of the dump valve, the EBCM cannot allow a pressure decrease or relieve the brake fluid in the accumulator. This Diagnostic Trouble Code (DTC) can be caused by a short in the Antilock Pressure Valve (APV), EBCM, or circuit between them.

TEST DESCRIPTION
- Check the resistance of the dump valve solenoid winding.
- Check for a short to ground in the antilock pressure valve.
- Check if the connector repair corrected the condition.
- Check for a short to ground in the antilock pressure valve.

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.
