⁽¹⁾	Battery voltage with switch closed.

⁽²⁾	Approximately 9 volts while cranking engine.

1) Turn ignition off. Install BOB, leaving PCM disconnected. Turn ignition on. Cycle switch in question. Measure voltage between switch BOB test pin and ground. If voltage is not as specified, go to next step. If voltage is approximately as specified, switch is okay. If sent here from SWITCH MONITOR TEST in QUICK TESTS, temporarily substitute known good PCM and retest. If sent here from elsewhere in QUICK TESTS, return to QUICK TESTS.

2) Turn ignition off. Unplug switch connector. Turn ignition on. Check for battery voltage at harness connector PWR wire for the switch in question. If battery voltage exists, go to next step. If battery voltage does not exist, repair open PWR wire to switch.

3) Measure resistance between switch terminals. Operate switch. If resistance is less than 5 ohms with switch closed and greater than 10,000 ohms with switch open, switch is okay. If sent here from SWITCH MONITOR TEST in QUICK TESTS, return to QUICK TESTS. If resistance is not as specified, replace switch.
