Solenoid Valve
- Turn ignition switch to the "ON" position. Connect voltmeter across ground and terminal No. 32 of ECU connector. Jumper terminal No. 27 of ECU connector to ground.
- Solenoid valve relay should switch on and voltmeter should register battery voltage.
- If fault is indicated, check wiring harness from ECU connector to hydraulic modulator. If wiring is not at fault, substitute a good relay and retest.
