There is a known issue affecting some vehicles whereby a Chrysler-issued TIPM firmware change reversed the operation of Front Turn Signals and Fog Lamps. It is easily remedied in a few minutes by swapping 2 (or 4) wires where they enter the backside of one of the TIPM wire harness connector plugs. This document is based on the Chrysler-issued Dealer Bulletin detailing this official corrective procedure. Unfortunately, we have no way of determining in advance which TIPMs and into which vehicles the mismatch will manifest. If, after installing your newly purchased TIPM, your front turn signals and fog lamps (if equipped in your vehicle) function normally (most cases), you do not need to do anything further and may discard this document. If upon installation you notice any of the following or similar symptoms, follow the procedures documented herein:
- My vehicle has fog lamps, and they flash when I operate the turn signal controls. Likewise, when I turn on my foglamps, both front turn signals go on steady.
- My vehicle doesn't have fog lamps, but when I operate my turn signals, either one or both signal lights don't respond at all or flash in a fast-busy mode.
- It is the centermost, smallest plug, oval in shape with a white face and light gray housing.
- Before proceeding, it is highly advisable to take a closeup photo of the back side of this plug, clearly showing all the wire colors and their starting locations. This is so that you can always restore the wires to their original cavities if you accidentally move the wrong wire or the procedure does not yield the expected results.
- Using the pointy end of a partially-straightened paperclip, insert it into the front side of the appropriate cavity to gently pry the tiny tab that grips the wire, all while gently pulling wire loose from the back. Re-watch video if necessary. The tiny gripping tab will automatically secure a wire when you merely push it into its new cavity.
- If there is no wire in 7 or no wire in 11, move the wire that is present anyway.
- If it appears from wire coloring that this procedure has already been performed, it may mean that your old TIPM merely had the opposite firmware of your replacement. Swap whatever wires are in 7 & 11 anyway.
- Swap pins 9 & 16 with each other irrespective of wire color, using the same method you used to swap 7 with 11.
- If either 9 or 16 is absent, move the wire that is present anyway.
To Finish:
- Re-attach front faceplate to the C4 Connector
- Reinstall TIPM as you had before
- Reconnect Battery cables to battery (remember, reconnect Positive first, for safety.
- Start vehicle and verify all functions that were working are still working. If not you will need to follow the instructions on the flyer we included with your purchase one more time. Verify that your Turn Signals (and Fog Lamps if equipped) are now functioning properly.
