Not so challenging repair

If the remote start on a 2009-2010 Dodge Challenger is intermittently inoperative, flash reprogramming of the Totally Integrated Power Module (TIPM) will be necessary with new software.

Intermittently, the vehicle may not perform a remote start when the FOB is pressed twice, and the headlights will flash once. The engine starts only when the start push button is pressed or when the FOB is used in the WIN.

Two TIPM calibrations may be displayed, one for model year 2009 and one for model year 2010. Make sure that you select the corresponding model year flash for the vehicle.

First check for codes, record and repair as needed before proceeding further. If the Remote Start Inhibit DTC “Power Loss” is present in the TIPM, then the TIPM must be flash reprogrammed with new software.

Using the wiTECH diagnostic application for flashing, a TIPM is available through the wiTECH diagnostic application. For instructions, select the “HELP” tab on the upper portion of the wiTECH window, then “HELP CONTENTS.” This will open the Welcome to wiTECH Help screen.

Clear any DTCs that may have been set in other modules due to reprogramming.
