Test 4: Inlet Solenoid Valve Problem
- Disconnect ABSCM/HU connector. Start engine and run at idle. Measure voltage between ground and ABSCM/HU connector terminal No. 1. See Figure . If voltage is 10-15 volts, go to next step. If voltage is not 10-15 volts, repair wiring harness between battery, ignition switch and ABSCM/HU connectors.
- Turn ignition off. Measure resistance between ground and ABSCM/HU connector terminal No. 23. See Figure . If resistance is less than .5 ohm, go to next step. If resistance is more than .5 ohm, repair wiring harness between ground and ABSCM/HU.
- Check contact at ABSCM/HU connector, generator and battery. If connector contacts are poor, repair contacts. If contacts are okay, go to next step.
- Reconnect all connectors. Erase memory. Recheck for trouble codes. If same trouble code returns, replace ABSCM/HU. If other trouble codes exist, go to proper test procedure. If no trouble codes exist, problem was a temporary poor contact. Recheck harness and connectors.
