Notes:

• ◆ The dash panel insert (with integrated immobilizer) is adapted to the engine control unit. Adaption to the engine control unit must be performed if the dash panel insert is replaced.
• ◆ After adapting dash panel insert to engine control unit, vehicle key matching is required .
• ◆ If there is no authorised ignition key available, engine control unit and all keys must also be replaced=> Page 01-415.

Requirement:

• ● Vehicle diagnostic, testing and information system VAS 5051 connected up and vehicle self-diagnosis selected => Page 01-3

Sequence of operations

• ‒ Insert old (authorised) ignition key in ignition lock and switch on ignition.
• ‒ Establish immobilizer identification number by starting immobilizer self-diagnosis at old dash panel insert => Page 01-358.

If this is not possible:

• ‒ Establish immobilizer identification number by starting engine control unit self-diagnosis.

→ Display on VAS 5051:

• ‒ From list -1- select vehicle system "01 - Engine electronics".
• ‒ Wait until next display appears.

→ Display on VAS 5051:

•     1 -    Engine control unit identification
•     2 -    Immobilizer control unit identification

Note:

With certain engine control units, it is also possible to read out immobilizer control unit identification in measured value block 081.

• ‒ On the basis of the 14-position immobilizer/engine control unit identification number, request 7-digit PIN from appropriate Sales Centre/importer.

Note:

The PIN is only valid for one day, after which a new number has to be requested. The PIN is of no use to the customer or other dealerships.

• ‒ Touch ▸ key.
