1) Turn ignition off. Connect BOB. Leave PCM disconnected. Turn ignition on. Ground appropriate BOB test pin. If solenoid does not operate properly, go to next step. Return to QUICK TESTS if sent here from there. Solenoid is okay if it functions properly.
2) Turn ignition off. Unplug suspect solenoid connector. Turn ignition on. Measure voltage between VPWR wire on harness connector and ground. If voltage is higher than 10 volts, go to next step. If voltage is not as specified, go to PINPOINT TEST VPWR.
3) Inspect wire to solenoid for shorts or open circuit. Repair wire as necessary. If wire is okay, replace solenoid.
