Easy TPMS Reset Instructions
I just like to share my experiments with resetting the TPMS on my 2010 Armada Platinum. I found the attached post on a Nissan forum and it works pretty well as listed.
I bought 4 new winter tires, with wheels and sensors. After install, the TPMS obviously didn't recognize the new wheels.
1. If you don't have a TPMS reset tool, set your tire pressures as follows:
FL = 36psi; FR = 33psi; RR = 30 psi; RL = 27 psi
2. Find the little white TPMS connector. In my Armada, it was taped to the wires going to the OBD connector, above the gas pedal.
3. Stick a 10" or so piece of wire into the connector, ensure it connects the pin inside the connector. Leave the other end dangling.
4. Turn the ignition switch to ON (don't start the truck yet), wait for your dash warning lights to go off.
5. Touch the free end of the wire to the bare metal bracket (i.e. ground it) 5 times within 10 seconds. If successful, your TPMS warning light on the dash starts flashing. This means you've put the computer in learning mode.
6. Start the truck and drive it for about 10 - 15 minutes, at speeds over 40 km/hr. The TPMS sensors in the wheels will wake up and advertise their presence to the monitoring system. The monitoring system knows which wheel is which due to the pressure differentials. Once the system registers the new sensors, the flashing light will go off and your display (if fitted) will show the 4 pressures.
7. Shortly after, the light may come on again, because your left rear tire pressure is too low. So don't forget to reinflate your tires to proper pressures again.
A few other notables:
- The display shows tire pressures in the order I indicated above, i.e. from Front Left (at top) to FR, RR and Rear Left (at bottom) clockwise around the truck.
- My TPMS readings are about 3 psi lower than my gauge.
Hope this will help someone else too. Now I'm comfortable I can reset the system again in the spring when I put the summers back on.
