I just swapped wheels with someone who also has a 5th gen 4Runner for reasons that aren't important. We both got TPMS lights that came on. Is there any easy way to reset it?
There isn't a reset button. The new TPMS modules don't have them, they're programmed through the OBD-II port. Discount Tire will reprogram your TPMS sensors to the truck free of charge.
I just dealt with this. I used the ATEQ Quickset. It will upload new tpms sensor id codes to the ECU. It will not read or activate sensors. If you know your codes this is the cheapest way to DIY tpms fix (not disable). It can also download currently installed/unknown tpms codes from an ecu.
The spare can be tricky. It's code is already in your ECU but its is not labeled. Its just one of the five codes the ecu needs to keep the light off. The best test method was to deflate each tire under 25lbs to see light go on, then inflate to see light go off. Was better than driving 20 miles to see if I had the correct codes in ecu.
Adding, wish I had a discount tire by me. They do this for free.
