Checking component and wiring

Check outside temperature sensor resistance.

Check signal cable between control module #B29 (#B39) and outside temperature sensor #1 for a short-circuit to ground according to Short-circuit to ground, permanent faults

HINT: With the ignition on and outside temperature sensor connector disconnected the voltage between #1 and ground terminal should be approximately 5V. 

Remedy as necessary.
