Repair Procedures: Inspection
- Ignition "OFF"
- Disconnect ambient temperature sensor.
- Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature.

- If the measured resistance is not specification, substitute with a known-good ambient temperature sensor and check for proper operation.
- If the problem is corrected, replace the ambient temperature sensor.
