Right hand drive models
1. Turn off the air conditioner. Turn the ignition key to position "ON".
2. Check the voltage between the output "6" connector of the electronic control unit for the injection system and mass. If the voltage matches the battery voltage, replace the ECM and retest. If the voltage does not match the battery voltage, check the circuits between the fans and the ECM.
Note: The check is made with the connector connected.

Note: Do not use this troubleshooting algorithm if the A/C compressor is not running.
1. Remove and test the cooling fan motor relay and condenser fan motor relay from the relay box. If the relays are faulty, proceed to step #2. If the relays are faulty, they should be replaced.
2. Install the cooling fan motor relay and relay box condenser fan motor relay.
3. Short to ground output No. 12 of the connector of the electronic control unit for the injection system.
4. Turn the ignition key to position "ON".
If the fans rotate, check that the A/C ECU connector has no loose contacts, otherwise replace the A/C ECU. If the fans do not rotate, repair open in the circuit between the ECM and the fan motor relay.
