General

Actual values:
Via the Hand-Held-Tester (HHT) up to 8 different Infrared (IR) transmitter keys can be tested for locking approval. Additionally, the battery condition and synchronization of each individual IR transmitter can be tested. The Hand-Held Tester also indicates the number of recently currently used IR transmitter. Lastly, an indication is given if the Remote Central Locking (RCL) control module (N54) is "married" (via an identification code) to the vehicle. The readout of actual values is menu driven.

De-synchronization
Loss of an IR transmitter key requires the de-synchronization of the RCL control module (N54) and the replacement of the mechanical locks. De-synchronization is only possible using the HHT and is menu driven. After de-synchronization, all still existing IR transmitter keys must be synchronized (see owner's manual).

Blocking IR transmitter keys
Via the HHT, IR transmitter keys can be irrevocably locked (only upon vehicle owner's consent). The blocking of individual IR transmitter keys is menu driven.

Version coding
Replacement of RCL control modules requires version coding via the HHT. The version coding is menu driven.

CAUTION!: The RCL control module (N54) and engine control module are "married" together via an identification code exchange. These identification codes can not be changed and this code remains with the vehicle for its service life. Only the mechanical locks can be replaced.

If the customer loses an IR transmitter key (which includes a mechanical key):
The vehicle's RCL identification code remains, the lost IR transmitter key(s) is de-synchronized via the RCL control module. To maintain vehicle security, all mechanical locks should be replaced using a new mechanical lock number code. You must notify your facing PDC of any mechanical lock changes, by using the Lock Change Notice Form.

If the RCL control module is defective:
A new RCL control module must be specially ordered for the specific vehicle, using the same RCL identification code as the previously installed RCL control module. Therefore, it is impossible to swap control modules (either RCL or engine control modules) for troubleshooting purposes.

If a mechanical lock or key is defective:
Replace the mechanical lock or key with a new one, using the same mechanical lock code number (special order from your facing PDC).

If the customer loses an IR transmitter key (which includes a mechanical key):
The vehicle's RCL identification code remains, the lost IR transmitter key (s) is de-synchronized via the RCL control module. To maintain vehicle security, all mechanical locks should be replaced using a new mechanical lock number code. You must notify your facing PDC of any mechanical lock changes, by using the Lock Change Notice Form.
