DR-10A Fault Code 33 A/C Cut-Out Relay

1. With diagnostic read-out tool connected to engine test connector, then connect a voltmeter between dark blue/orange wire terminal of A/C cut-out relay 3 way connector and ground.
2. Place system in ATM test mode code 05.
3. If voltmeter indicates voltage is within 1 volt of battery voltage, proceed to step B. DR-10B A/C Cutout Relay Control Circuit
4. If voltmeter reading cycles between 0 and 5 volts, proceed to step C. DR-10C A/C Cut-Out Relay Pull In Coil Windings
5. If voltmeter reading is not cycling, but reads between 0 to 1 volt, disconnect logic module black electrical connector. If voltmeter reading is now within 1 volt of battery voltage, replace logic module. If reading is not within 1 volt of battery voltage, check dark blue/orange wire for short circuit to ground.
