Ambient Temperature Sensor Diagnostics

The outside temperature function is supported by the ambient temperature sensor, a signal and ground circuit hardwired to the compass/temp module, and the Compass/Temp Mirror display.

If the Compass/Temp Mirror display indicates "SC", the ambient temperature sensor circuit is shorted to ground.

If the Compass/Temp Mirror display indicates "OC", the ambient temperature sensor circuit is open.

The ambient temperature sensor can be diagnosed using the following Sensor Test. First, confirm that °C is not being mistaken for °F or vise-versa. If the ambient temperature sensor and the circuits are confirmed to be OK, but the temperature display is inoperative or incorrect, replace the Compass/Temp Mirror.
