DR-12A Fault Code 35 Radiator Fan Relay

1. With diagnostic read-out tool connected to engine test connector, connect voltmeter between dark blue/pink wire of radiator fan relay small 3 way connector and ground.
2. Place system in ATM test mode code 04, voltmeter should be cycling between 0 and 14 volts.
3. If voltmeter reading is within one volt of battery voltage and is not cycling, proceed to step B.
4. If voltmeter reading is cycling between 0 and 3 volts, proceed to step C.
5. If voltmeter is not cycling and reads 0 to 1 volt, disconnect logic module white electrical connector. If voltmeter reading is now within 1 volt of battery voltage, replace logic module. If voltmeter reading is still not within 1 volt of battery voltage, check dark blue/pink wire for short circuit to ground.
