Checking Components And Wiring

Check the signal cable between control module terminal #B44 and air conditioning (A/C) relay terminal #4. Check for a short-circuit to supply voltage.

HINT: Use a test lamp with at least a 3 W bulb to determine whether the cable is short-circuited to supply voltage. 

Remedy as necessary.
