This can be done in 5-10 minutes. All you need is a wire connector that can directly connect two wires. What I used was a Scotchlok wire connector (see the first picture below). Here is how:
Steps (on my '05 4Runner):
- Disconnect the battery (Although I did not do this)
- Take out the screw that holds the black plastic panel located below the glove box
- Gently pull the black panel and it should just pop out
- Drop the panel and you will see that the TPMS module is right there
- Unplug the harness (as show in the second picture below)
- Use utility knife or scissors and cut the yellow type open (BE CAREFUL-Not to cut the wires!!!!)
- Inside the yellow type there is another layer of black type, cut that open as well (again, BE CAREFUL Not to cut the wires!!!)
- Now, look for two wires: the Pink-Black one (TPMS) and the White-Black (ground) wire (see below the third picture)
- Use Scotchlok wire connector to connect the Pink-Black wire and the White-Black wire (watch youtube Scotchlok Wiring Demo clip here: ScotchLok Wiring Connector Demonstration - etrailer.com - YouTube) NOTE: Check both channels inside the connector. If one channel is blocked, you need to cut out the plastic block to make adjustment so that the wire can go through just like the other channel).
Done! The TPMS light is now bypassed and the light will never come back on. (Note: this mod is reversable by simply removing the connector or wire a switch to turn it on or off: see
TPMS light bypass switch)
Since the TPMS is disabled, be sure to check your tire pressure regularly.
