Condition
Some customers may comment on an intermittent dead battery or of the battery going dead overnight.
Cause
This condition may be caused by the instrument panel brightness lever, located on the overhead console, being slightly engaged but not enough to turn on
the interior courtesy lamps. The slightly engaged switch causes the Dash Integration Module (DIM) to cycle between active and inactive which wakes up
other modules on the Class 2 data line. This causes the vehicle to remain active. The scan tool will not indicate that the switch is active.
Correction
Technicians are to replace the overhead console assembly with an newly designed part using the following procedure:
Remove the roof console. Refer to the Roof Console Replacement procedure in SI.
