PRC Circuit Short To Ground

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 and PRC ride selector switch connector. Set VOM on 200K-ohm scale. Measure resistance between Blue/Yellow wire and ground. If resistance is greater than 10 k/ohms, proceed to PINPOINT TEST Q12. If resistance is 10 k/ohms or less, repair Blue/Yellow wire between control module and switch for shorts to ground as necessary.
