This bulletin is being revised to include additional information and reference to new corporate bulletins on SIR module handling procedures. Previous
divisional publication numbers were:
GM of Canada
93-8C-123
CONDITION:
On the 1993 D-car, the "AIR BAG" warning lamp may stay on, and one or more Diagnostic Trouble Codes (DTC's) related to the PSIR module may be
set. Likely SIR DTC's may include 15, 16, and/or 17.
CAUSE:
Isolated reports suggest that the connector for the passenger side SIR module may contact an I/P stud, possibly damaging the connector and causing an
open or short circuit in the wiring. This condition was corrected in production after the VIN breakpoint above. This condition affects the passenger side
SIR module only, and cannot cause inadvertent air bag activation. The warning lamp will be "on" if this condition occurs.
CORRECTION:
1.
Disable the SIR system. Refer to page 8C-7 of the Service Manual.
2.
Remove the upper I/P trim pad, following the directions on page 8C-24 of the Service Manual.
3.
Locate the wiring connectors on the right hand side of the SIR module, as shown in Figure 1.
