Solenoid Valve Circuit
If an open or short circuit occurs in the release valve, build-up valve or the wiring harness, the warning light will be turned on and all anti-lock brake functions will cease. To determine correct power supply to the ECU, perform checks and compare with voltages described in SOLENOID VALVE CIRCUIT VOLTAGE SPECIFICATIONS table.
