4.4.2 Important Tips for Testing Airbag Systems
• The current software may only identify the 5WK 40 060 system for 1993. For earlier vehicles
with this airbag system (1991–92), try identifying the vehicle to the scan tool as a 1993 model
to obtain the AIRBAG menu selection.
• The replacement of airbag modules always require ZCS coding at installation before they are
put into operation.
• Always disconnect the battery and wait a minimum of 10 minutes for the airbag module
capacitor to discharge before working on any airbag system.
