DR-25-Radiator Fan Relay

1. Turn ignition switch to the On position, then using a suitable voltmeter, check voltage at dark blue/pink wire of the radiator fan relay.
2. If voltmeter reads battery voltage, proceed to Step 13.
3. If voltmeter reading is not as specified, turn ignition switch to the Off position.
4. Disconnect the SMEC 60-way electrical connector and check for terminal push out or damage. Repair as needed, then proceed to Test 37.
5. If no damage is found, turn ignition switch to the On position.
6. If voltmeter reads battery voltage, replace SMEC, then proceed to Test 37.
7. If voltmeter reading is not as specified, turn ignition switch to the Off position, then disconnect radiator fan relay.
8. Using a suitable ohmmeter, check continuity between radiator fan relay dark blue/pink wire to ground.
9. If ohmmeter shows continuity, repair short in dark blue/pink wire to ground, then proceed to Test 37.
10. If ohmmeter reading does not indicate continuity, use a suitable voltmeter and check voltage at dark blue wire of the fan relay connector.
11. Turn ignition switch to the On position. If voltmeter reads battery voltage, replace radiator fan relay, then proceed to Test 37.
12. If voltage reading is not as specified, repair open in dark blue wire of fan relay to harness splice. then proceed to Test 37.
13. Turn ignition switch to the Off position.
14. Disconnect the SMEC 60-way electrical connector and check for terminal push out or damage. Repair as needed, then proceed to Test 37.
15. If no damage is found, use a suitable voltmeter and check voltage at terminal No. 57, dark blue/pink wire of the 60-way electrical connector.
16. If voltmeter reads battery voltage, replace SMEC, then proceed to Test 37.
17. If voltmeter reading is not as specified, repair open in dark blue/pink wire between 60-way electrical connector and fan relay, then proceed to Test 37.
