Checking components and wiring

Check the resistance of the outside temperature sensor.

Check the signal cable between control module terminal #B29 (#B39) and outside temperature sensor terminal #2. Check for a short-circuit to ground.

HINT: With the ignition on and the outside temperature sensor connector disconnected, the voltage between #2 and the ground terminal must be approximately 5 V. 

Remedy as necessary.
