This bulletin supersedes TSB-22-55-002REV2 issued January 2024 to update the affected vehicles
and applicable part numbers (by VIN). Revisions are italicized and indicated by ◄.
PURPOSE
This Campaign Bulletin provides updated instructions to replace the A/C AUTO AMP and
perform reconfiguration of A/C AUTO AMP and run diagnostics using MUT-3SE. This
reconfiguration will stop the A/C setting from changing even if the microcomputer reboots.
Please replace the A/C AUTO AMP and perform reconfiguration upon customer complaint.
BACKGROUND
Inappropriate software programming may cause an internal error in the AC AUTO AMP. The AC
system turns off unintentionally and does not automatically turn back on. The AC may be
turned back on manually within a few seconds; however, stored settings such as temperature,
are lost. Upon customer complaint, please replace the A/C AUTO AMP, reconfigure the A/C
AUTO AMP software and diagnosis using MUT-3SE.
The phenomenon is caused by the rebooting of the microcomputer on A/C AUTO AMP (a
protective function) and after the system is off for a few seconds it will restart with A/C
setting of 75o fahrenheit or remain off.
