CDR23 replacement

The CDR23 is provided in active production mode as a spare part. Each time the vehicle is started, the stored PCM2 code is compared with that in the instrument cluster.

If a match is found, the device is operational. No further checks are made while the device is connected to the vehicle electrical system.

If no match is found, the device switches off after 30 seconds and the PROTECTED message appears in the display. The device is not operational. Coding of the PCM2 (from IPAS) must be carried out.
