SERVICE MANUAL UPDATE-SEC.9 SIR FUSE REMOVAL PROCEDURE

Subject: SIR FUSE REMOVAL

Model and Year: 1990 GEO STORM

This bulletin should be added to Sections 9J, 9J-A, and 9J-B in the Service Manual (ST371-90).

The SIR disable/enable procedures on pages 9J-6, 9J-A-6, and 9JB-2, 3, 4 and 5 refer to removing the SIR fuse #3 when disabling the SIR system. This is incorrect. The correct SIR fuses to remove, located in the fuse block below the driver's side instrument panel are fuses C-22 and C-23 (Figure 1).

Remove these two fuses whenever performing service on the SIR system or on the steering column.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
