Checking Tire Pressure Sensors
- Ignition on.
Each tire pressure sensor has its own id-number which is sent and stored in central electronic module (CEM).
First read out the frozen values for the diagnostic trouble code under the tab DIAGNOSTICS and note the ID number of the sensor that has caused the diagnostic trouble code to be stored. The ID-number is divided in four parts: "Sensor-ID part 1" - "Sensor-ID part 2" - "Sensor-ID part 3" - "Sensor-ID part 4".
Use the special tool and activate one sensor at a time for all four wheels, to read out the ID numbers of the installed sensors. If the special tool does not have a display, click on the VCT2000-symbol to read out latest received ID-number, tire pressure, and battery voltage.
NOTE:- Erase any old readings in the tool before starting reading.
- Use only one special tool at a time in the vicinity of the vehicle.
Compare the read-out ID number for the relevant wheel with the ID number that is stored with the DTC.
If a sensor does not respond during the test:
- Replace the tire pressure sensor for the relevant wheel. It is probably the sensor that caused the DTC to be stored.
If all sensors respond:
- The sensor that caused the diagnostic trouble code to be stored has probably had an intermittent malfunction. Replace the tire pressure sensor for the relevant wheel.
