Test E - Yellow Light Flashing & Red Light Off
- Turn ignition off. Unplug control module connector. Turn ignition on. Shake instrument panel harness while measuring voltage. Measure voltage at control module connector pin No. 1 and at pin No. 9. If voltage is intermittent or is less than 9 volts, check for open in wiring between fuse panel and connector pin No. 1 and pin No. 9.
- If voltage is steady and 9 volts or more, turn ignition off. Disconnect battery. Measure resistance between control module connector pin No. 12 and ground. Shake module harness while measuring resistance. If resistance is less than 100,000 ohms or resistance varies, repair short in Black/Orange wire between diagnostic connector and module connector.
- If resistance was 100,000 ohms or more and steady, measure resistance between module connector pin No. 4 and ground. Shake module harness while measuring resistance. If resistance is one ohm or more, repair open in Black/White wire between module connector pin No. 4 and body ground. If resistance is less than one ohm and is steady, replace control module.
