TO: ALL MERCEDES-BENZ PASSENGER CAR DEALERS

DATE: December 1995

SUBJECT:
MODELS 124 AND 201 WITH ANTI-THEFT ALARM (ATA) AS OF M.Y. 1993,
UPGRADE TO ALARM TESTER 924 589 00 21 00

In Service Information MBNA 58/80, dated April 1995, we recommended the self-fabrication of an adapter harness to expand the capability of the MB Alarm System Tester to allow diagnosis of the anti-theft alarm (ATA) in vehicles as of M.Y. 1993.

As an alternative, Becker of North America, Inc. is now offering an upgrade and modification service for the MB alarm system tester to include diagnosis of M.Y. 1993 and later vehicles, without the use of an additional harness.

Dealers can send their MB alarm system tester directly to Becker of North America, Inc. (address below) to have these features installed for a flat fee of $70.00 (parts and labor included).

Note:
The flat fee quoted above assumes the MB alarm system tester is fully operational and functional. Any required repairs to the basic tester will be charged extra prior to the upgrade and modification.





The modified tester can be identified externally by the addition of a toggle switch to the control unit itself (enlargement, Figure 1).

All modifications are incorporated internal to the control unit.
