Fault-Tracing Information

Fault-tracing

Checking the remote receiver
The remote receiver is fitted above the headlining to the left of the central lighting panel, level with the sun visor. The remote receiver is connected to Central electronic module (CEM) or to Keyless vehicle module (KVM) depending on the vehicle's configuration.
Check whether the diagnostic trouble codes for missing communication with the remote control are stored in the Central electronic module (CEM) or in the Keyless vehicle module (KVM), depending on the configuration of the vehicle.
Check that the remote receiver works by pressing the lock and unlock button on the remote control. The vehicle should be locked and unlocked.

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

Does the remote control and remote receiver work?

Yes - Checking tire pressure sensors

No - DONE

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.
