Re: TPMS Reset Procedure
it does matter, as the vehicle has to know what tire is in which position, unlike most manufacturers, you have to do a complete procedure on these vehicles, as it only has 1 receiver, as in some manufacturers use independent receivers for each wheel, and they do not have a procedure to relearn positions, it does it automatically in some cases.
if you have the vehicle thinking the tires are set in position, say you rotate the tires and now the RF has a leak, well that tire was in the right rear before rotation, and now it has a leak, but the vehicle thinks its in the right rear, because the vehicle was never reset to have the tire positions learned.
easiest way to tell is with a tech 2 and the kent moore tool for the TPM systems. you can diagnose systems relatively easy with both tools.
it gives you the ability to view which sensor is in each wheel, by providing individual TPM sensor ID's unique to each wheel and vehicle. if you have a system that is suspect to have an issue with the system, you can verify that the vehicle knows where each tire is placed, it will display the ID information on the tech 2 for each individual wheel, and which position they are in.
