Component Testing: Relay
- To check radiator fan relay, turn ignition on and check for battery voltage at ignition switch circuit terminal at radiator fan relay. See IGNITION SWITCH CIRCUIT WIRE COLOR ID table. If battery voltage exists, go to next step. If voltage is 0-1 volt, go to step 3).
- With ignition off, disconnect 60-pin connector from PCM. PCM is located on left front corner of engine compartment. Turn ignition on. Check for battery voltage at proper cavity of connector. To identify the proper cavity, see PCM PIN IDENTIFICATION table. Also see Fig 1 or Fig 2 . If battery voltage exists and female terminal is not damaged, replace PCM. If voltage does not exist, repair open or short in Dark Blue/Pink wire from radiator fan relay to PCM.
- With ignition off, disconnect PCM connector from PCM. PCM is located on left front corner of engine compartment. Turn ignition on. Check for battery voltage at proper wire color of radiator fan relay. See IGNITION SWITCH CIRCUIT WIRE COLOR ID table. If battery voltage exists, replace PCM. If voltage reading is 0-1 volt, go to next step.
- With ignition on, test for battery voltage at Dark Blue/Pink wire at radiator fan relay. If battery voltage exists, replace radiator fan relay. If voltage does not exist, repair open or short in Dark Blue/Pink wire between radiator fan relay and PCM. Turn ignition off, reconnect PCM connector to PCM and test system.IGNITION SWITCH CIRCUIT WIRE COLOR ID
