Each tire pressure sensor has its own ID number which is transmitted to and stored in the upper electronic module (UEM). Read off the last stored ID number by clicking on the VCT2000 symbol. The last stored ID number is displayed until a new ID number is received and stored.

Use the following special tools to activate the sensor. Use the following special tools to activate the sensor.

see 9512963

NOTE: Ensure that the special tool is positioned under the edge of the rim against the tire where the sensor is installed. The sensor will not be activated if the tool is against the rim. The sensor must then be held in place for approximately 5 seconds for the signals to be correctly received. Use only one special tool at a time in the vicinity of the car.

NOTE: Carry out the above in an area away from where other cars are being driven. The receiver can pick up signals from sensors on other cars. An incorrect ID number would then be displayed.

Repeat this procedure for each wheel. Different ID numbers must be displayed.

HINT: If a sensor does not respond during the test this indicates that the rim does not have a sensor installed, the sensor may be damaged or may be a sensor intended for another make or model.
