DR-15A Fault Code 35 Radiator Fan Relay

1. Connect diagnostic read-out tool to engine test connector, then a voltmeter between dark blue/pink wire of radiator fan relay connector and ground.
2. Place system into ATM Test Mode Code 04. If voltmeter reading is cycling and relay clicks, check circuit for poor connections.
3. If voltmeter is not pulsating but is indicating voltage is within 1 volt of battery voltage, proceed to
test 15, step B.
4. If voltmeter is pulsating between between 0 and 3 volts, proceed to Test 15, step C. If voltmeter is not pulsating but is indicating voltage is 0 to 1 volt, disconnect logic module red electrical connector and proceed as follows:
a. If voltage is now within 1 volt of battery voltage, replace logic module.
b. If voltage is not within 1 volt of battery voltage, proceed to Test 15 step C.
