Some customers may comment that during night time, all backlighting (IPC, radio, HVAC, etc) flashes or flickers. This condition is intermittent and typically occurs after replacement of the body control module (BCM).
Correction
Important
DO NOT replace any hardware for this condition.
A revised calibration has been released to address this condition. Technicians are to reprogram the IPC using the Service Programming System (SPS) with the latest calibration available on TIS2WEB, selecting 'IPC Backlight Blip Fix Only'. Refer to the SPS procedures in SI.
When using a multiple diagnostic interface (MDI) for reprogramming, ensure that it is updated with the latest software version.
When using a Tech 2(R) for reprogramming, ensure that it is updated with the latest software version.
During programming, the battery voltage must be maintained within the proper range of 12-15 Volts. Only use the approved Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.
Warranty Information
For vehicles repaired under warranty, use the applicable published labor operation.
