Sensor Missing

Sensor missing

Checking the receiver
The receiver is in the rear view mirror. It receives signals from both the remote control and tire pressure sensors. The remote control can be used to check that the receiver is working.
Check the function of the receiver by pressing the locking and unlocking button on the remote control. The vehicle must lock and unlock.

Note! Fault-trace the symptoms if the remote control and receiver are not working.









Are the remote control and receiver working?

Yes - Checking the tire pressure sensors

No - DONE

-------------------------------------------------

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.

Use special tool951 2963 951 2963 to activate one of the sensors. The special tool activates the sensor which then starts to transmit information to the upper electronic module (UEM). The ID number of the sensor can then be read in the display.

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.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.
Read out the ID numbers for the tyre pressure sensors by clicking on the VCT2000 symbol.
Use the following special tools to activate the sensor.
- 951 2963 951 2963
The special tool activates the sensor, which then starts to send information to the Upper Electronic Module (UEM). After activating a sensor, press the "Show data" button for the relevant wheel. Repeat activation for all wheels. Different ID numbers should appear.

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.

Check that the relevant sensor(s) respond. Test different wheels to ensure that different ID numbers are displayed.
