This bulletin contains additional vehicles involved and is being issued to supplement bulletin 0A25 which was only sent to dealers with affected vehicles.

All of the vehicles indicated in the Vehicles Involved section of this bulletin require inspection of the SIR Inflator Module. the Service Procedure section has been modified to include inspection instructions, and a separate Repair Code has been added to the Parts & Labour Claim Information section.
