PRC Control Module Power
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. Turn ignition on. Set VOM on 20-volt scale. Measure voltage between Black/Yellow wire and ground. If voltage reading is greater than 10 volts, proceed to PINPOINT TEST Q3. If voltage reading is 10 volts or less, check 15-amp fuse or repair Black/Yellow wire between PRC control module and interior fuse box.
