Note:

New/old dash panel inserts or old engine control unit must always be released.

Requirements:

• ● Vehicle diagnostic, testing and information system VAS 5051 connected up and vehicle self-diagnosis selected
• ● Ignition on

Sequence of operations

• ‒ Establish immobilizer identification number by starting self-diagnosis for appropriate control unit (engine or immobilizer).
• ‒ On the basis of the 14-position immobilizer 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.

→ Display on VAS 5051:

• ‒ From list -1- select diagnosis function "Release (PIN)".

  "Press here to display entry keypad".
