Official summary

This Preliminary Information communication provides information to the technician about vehicles that may have a power lift-gate that is inoperative from all the switches and the keyless entry transmitter only with the ignition in the off position. Technician will need to check for battery voltage on circuit 5985 going to the Engine Control Module and to the Transmission Control Module.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
