QuestionQUESTION: I need to know how to reset the Body Control Module, I have unhooked the battery but that didn't stop the flasing lights on the dash panel where the a/c, window washers, etc. are located. THis happened once a few years ago and the shop reset it but they told me it was just a matter of pushing the flashing lights in a certain sequence. Is this correct and how can i stop these lights from flashing?
ANSWER: CALIBRATION/DIAGNOSTICS TEST ENTRY
TO INITIATE TESTS:
Set Blower motor ON HIGH
Set Mode position to Panel
Open all A/C outlets
Set Temperature to Cold (Both slide pots if equipped)
Depress WASH and REAR WIPER button simultaneously for 5 Seconds (Until all LED's light)
RESULTS:
All LED's will turn on for 5 Seconds
Calibration Test is running when REAR WIPER and INTERMITTENT are alternately flashing. Cooldown test is running if A/C and RECIRC are alternately flashing.
Acceptable results is REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit.
After all tests have passed, Calibration Diagnostics and Cooldown can be run separately.
