Reset Procedure


Resetting Tire Pressure Monitoring Light

The tire pressure warning indicator will turn off when the tire pressure is restored within limits or the system is re-initialized.

The TPM reset switch is a non latching push switch installed on the center console below the A/C control panel. While pressed, the reset switch connects a ground to the TPM ECU.

The reset switch is used to initialize the TPM ECU. During initialization the TPM ECU adopts the current tire pressures as the nominal pressures.
