Checking the tire pressure sensors
- Ignition on.
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.
NOTE: The last stored value is erased when the ignition is switched off and on again.Activate one of the sensors by using the special tool: 9512987 The special tool activates the sensor which then starts to send information to the Upper electronic module (UEM) and the sensor's id-number can then be read in the character window.
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.
If a sensor does not respond during the test:
Check that a tire pressure sensor is installed on the rim. Install a new sensor if there is no sensor installed. If the sensor is installed but is still not working, it may be defective or be a sensor intended for another make or model. Replace the tire pressure sensor.
If all sensors respond:
Intermittent fault. The control module has previously detected that one or more sensors are not communicating. This may be because the vehicle previously had a wheel mounted without a functioning sensor.
