CODE 9077 "VIN'S IN CONTROL MODULES N2/7 AND N73 ARE NOT IDENTICAL" CURRENT AND STORED AFTER INSTALLING NEW AB MODULE

DEALER TECH TOPICS; JANUARY 2011

Reference Number(s): TT 01/11-J, Date of Issue: January 2011

MERCEDES-BENZ:	All
GROUP:	91.60 - Airbag

CAUSE / EXPLANATION

Coding is not locked into the AB module. Coding is not completed by the SDS under certain conditions.

CORRECTION

Unplugging the AB module for a few minutes resolved the issue. Similar conditions have been seen with the e-prom memory of other control modules and removing the power from the module locks the coding into the e-prom memory.
