Test Connector Continuity
WARNING: This page is about a different car, the 1992 Ford Probe. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect PRC control module connector. Set VOM on 200-ohm scale. Measure resistance between Blue/White wires in PRC control module connector and PRC test connector. If resistance is less than 5 ohms, proceed to PINPOINT TEST Q6. If resistance is 5 ohms or more, repair Blue/White wire between PRC control module and test connector for opens.
