This condition may be caused by a power liftgate microprocessor issue that could cause the power liftgate module to stop communicating on the
GMLAN Serial Data Bus.
If the power liftgate module is not communicating, remove the two power liftgate module fuses, wait a minimum of 1 minute , and reinstall the two
fuses; or disconnect the power liftgate module (disconnect all three connectors at the module), check and verify power and ground to the module, and
re-connect the power liftgate module. Verify communication. If communication is restored, then update the software in the power liftgate module.
A revised power liftgate module calibration has been released to address this condition. Reprogram the power liftgate module using the Service
Programming System (SPS) with the latest calibration available on TIS2WEB. 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 12-16 volts. Only use the approved Midtronics(R) PSC
550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.
