1. |
Connect ISAT and give the command "ELECTRICALLY HEATED REAR WINDOW" in the "ACTIVATE" menu. This command sends Batt + from pin 39 on the ACC control module to ICE and then check on pin 31 whether the electrically heated rear window is activated or not. ISAT will not move "*" if the electrically heated rear window is not activated. If this works, clear the diagnostic trouble code and check that it is not generated afresh.
