Action in service
- Check wiring harness between DME and electric fan
- Check power-supply voltage to electric fan
- Unplug electric fan and then measure resistance on electric fan between power-supply voltage (Pin 2) and activation (Pin 4) terminals. If the resistance is greater than 1 ohm respond by replacing the electric fan. Check wiring harness to electric fan cutoff relay.
- Replace electric fan cutoff relay.
