Control unit: Wheels
The TPMS will not work unless TPMS type wheels are installed on the vehicle. There are two different type of wheels used.
- Aluminum wheel type: The original equipment wheels have a "TPMS" mark (A) on them. The wheels also have counterweights (B) incorporated on the opposite side of the tire pressure sensor (C), to counterbalance the weight of the sensor.
- Steel wheel type: The original equipment wheels have a "TPMS" mark (A) on them, and a counterweight (B) balances the weight of the tire pressure sensor (C) by a size difference in the wheel disc holes.
