2.3.7. Placard Adjustment
This function allows you to change the tire pressure reference values
stored in the vehicle’s ECU using an OBD-II connection.
The Placard Adjustment function can be used when changing tires with a
different load index than the original tires, such as off-road tires, oversized tires or low-
profile tires, in order to keep the vehicle's TPMS system working and to prevent a TPMS
alert from being displayed on the dashboard.
Please note that after using this function, the tire pressure values on the standard placard
affixed to the vehicle no longer correspond to those registered in the vehicle’s ECU.
Warning, when you change the tire pressure reference values stored in the
vehicle’s ECU, you are changing the low pressure warning threshold.
Be certain of the values you enter so as not to put yourself at risk.
The Placard Value Adjustment function is only available for certain makes of
vehicles.
