How to disable the TPMS (Tire Pressure Monitoring System) instrument cluster
By Rudy Compart edited by onehundred80
This post is available as a PDF file. See the bottom of the postThe easiest way to disable it is to remove the wire from pin 2 and put it in the empty place of pin 6 . This will completely disable it and you will no longer have the light illuminate on the instrument cluster. This will not affect the HomeLink in any way so you don't lose that functionality.
There is a blank hole in position 6 and the connector goes together in one way only with the barb facing the hole in the face of the connector. Position #6 is at the end of the connector with the notch in it, study the ends of the connector and you will see the difference. My connector was covered in a foam tape which was disintegrating so I cleaned it all up.
To get at the TPMS/HomeLink connector, remove the dome light by removing the cover of the light by
gently prying around the edge of it, moving it out bit by bit
evenly, the use of a small trim removal tool is best.
The connector is not immediately visible; it is
not the one you see attached to the HomeLink module. The one you are looking for is the 6 pin connector beside, behind or on top of the HomeLink module. Gently pull it out of the dome light hole so you can work on it. I carefully disconnected the connector from the HomeLink module by pulling it down. This is a delicate item and I damaged mine slightly so be careful and not pinch it too hard. You can now separate the 6 pin connector. To do this slide a small screwdriver between the male and female connectors above the hole in the side, this hole can be seen in the pictures to spring the sidewall of the female connector over the little catch on the side of the male connector.
You now open the hinged part of the female connector this is the part of the connector closest to the module, this clamps the wires in place. By depressing the barb on the #2 connector pin with a toothpick through the hole the wire can be gently removed from the connector and slid fully into the blank hole at position #6. Slide it in so that the barb clips into the hole in the connector sidewall.
Reconnect the connector(s) and carefully stow them back beside the module so they do not interfere with the dome light body snaps. Finally, reinstall the dome light body and lens and you are finished. Voila, no more irritating dash panel light.
The 6 pin connector is shown separated in the top photo with the TPMS wire (in my case it was purple) relocated into position #6.
This photo shows the hinged section of the connector un-clipped to release the clamping pressure on the wires.
