2004 Explorer:
Pulled 15:
What it does: Rear Wiper Module, Cluster
Result: Stopped rear wiper from working, also cut of the Odometer/temp digital display for about 30 seconds. Start driving it comes on within that 30 seconds. Then starts to record miles once on.
Pulled 21:
What it does: Instrument Cluster, Compass, Flasher Coil
Result: The whole instument cluster is out, that means no gauges what so ever, plus the safety aspect of the flashers also being out, only light on the cluster that works is the high beam light. But no miles are reported.
Pulled 22:
What it does: ABS, IVD Controller
Result: This is for ABS, did nothing for the odometer on the 2004.
after playing with these a bit the service engine light did come on, easy reset by pulling the battery cable and reseting the computer. Note you lose everything like radio stations programed in and your trip miles.
Hope this help people here with newer Explorers. Oh, and I do not suggest doing this as it is highly illegal and my Uncle who works at Ford says that the car keeps track of the miles in the computer...makes sense but when was the last time they scanned the computer to see if the miles matched up...never in all the cars I have owned and turned in...and once the car is out of your hands then who knows who deactivated the miles...could of been the next guy, or the dealer...LOL Beats paying $2,000 to some shaddy shop to wire a switch in....lol
