Fault-Tracing Information

Fault-tracing

Checking the remote receiver
The remote receiver is located on top of and in the trailing edge of the headlining. 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).

Note! For trouble code CEM-C1D2105 the ID-number is not saved for the missing tire pressure sensor.

Use the special tool and activate one sensor at a time for all four wheels, to check if all sensors send ID-number correctly to the remote receiver. 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!
- When a new tire pressure sensor is installed, it must be activated from its transport mode. The sensor can only be activated using the special tool:
- Erase any old readings in the tool before starting reading.
- Use only one special tool at a time in the vicinity of the vehicle.

If a sensor does not respond during the test:
- Replace the tyre pressure sensor for the relevant wheel. It is probably the sensor that caused the DTC to be stored.

If all sensors respond:
- Erase diagnostic trouble codes (DTCs).
- Drive the vehicle for 10 minutes at a speed of at least 40 km/h.
- Now the trouble code shall be resolved.
