If the vehicle’s battery was not disconnected prior to removal of the TIPM, it may inadvertently blow a fuse or relay inside the fuse box. There may be multiple fuse boxes in the vehicle.
Often times there are communication issues present if the unit is installed back in the vehicle. One of the fastest and easiest ways to clear any soft codes in the vehicle is to do a reset.
Hard Battery Reset Procedure:
-
Disconnect the battery cables.
-
Clamp the cables together with the terminals touching (off the battery!)
-
Leave the cables maintained in this position for 30min. and then re-install.
HELPFUL TIP
Whenever doing a hard reset (global reset) always remove the ground cable first then the positive cable. When reinstalling a battery or just the cables install positive first then attach the ground. It's always best to do it this way so there are almost no issues causing an electrical spark on a module in the vehicle.
*This should clear any soft codes and communication issues with the vehicle’s PCI bus.*
If the light is on, then it will be best to scan for codes.
