# DIAG. INFO. ON THE POWER PASSIVE RESTRAINT SYSTEM

#### SUBJECT: Diagnostic Information on the Saturn Power Passive Restraint System

#### MODELS AFFECTED: All 1991-1993 Saturns

PURPOSE: This bulletin provides system performance information and diagnostic information consisting of a complaint-condition cause table and diagnostic chart.

#### NOTE: This information will be published in the final 1991-1993 Saturn Service Manual.

SHOULDER BELT RETRACTOR/POWER PASSIVE RESTRAINT TRACK SYSTEM INTERACTION

Shoulder belt retractors, located in the, center console, are vehicle sensitive and will lock if the vehicle exceeds a 17 degree angle or 0.6 g of deceleration forces. Shoulder belt retractors may lock under moderate cornering or while descending a winding downhill grade. They may also lock while braking to a stop at a downhill intersection or on aggressive stops on any grade. The shoulder belt retractors will unlock when 6.35 mm (1/4in.) of belt is fed back into the retractor.

When the shoulder belt retractor is locked and the corresponding door is opened, the slider (mouse) will begin to move from the B pillar position to the A pillar position. However, the shoulder belt retractor will not unlock, which will cause the slider (mouse) to hesitate or stop as it rounds the corner from the B pillar. To correct this condition, close the door and release the shoulder belt retractor by allowing greater than 6.35 mm (1/4 in.) of belt to be fed back into the shoulder belt retractor.

PASSIVE RESTRAINT SYSTEM PERFORMANCE TEST

Vehicle Set-Up: Driver seated in vehicle, shoulder belts connected, both sliders (mice) at A pillar, ignition key out of ignition, doors closed.

#### NOTE: If passenger belt is at B pillar position, with key out of ignition, open and close passenger's door to get passenger belt to A pillar position.

ACTION VERIFY 1. Buckle driver's lap belt. Both belts go to B pillar. Turn ignition to RUN position. 2. Open driver's door. Driver's belt goes to A pillar. 3. Close driver's door. Driver's belt goes to B pillar. 4. Open passenger's door. Passenger's belt goes to A pillar. 5. Close passenger's door. Passenger's belt goes to B pillar. 6. Turn ignition Off. Driver's belt stays at B pillar. (Do not remove ignition key.) Passenger's belt stays at B pillar. 7. Remove ignition key. Driver's belt goes to A pillar. Passenger's belt stays at B pillar. 8. Open and close driver's door. Driver's belt stays at A pillar. Passenger's belt stays at B pillar. 9. Open passenger's door. Passenger's belt goes to A pillar. Driver's belt stays at A pillar. 10. Close passenger's door. Both belts stay at A pillar.

If system performance is not verified, continue to the "Passive Restraint Diagnosis" charts on the following pages.

13 MPH OVERRIDE TEST

1. Put vehicle on a lift, just high enough to allow the wheels to spin.

2. Get in vehicle and leave driver's door open. Start the vehicle and put the transaxle in Drive and slowly increase speed to 15 mph (24 km/h).

3. Verify driver's belt moves to B pillar.

#### NOTE: Driver's belt will stay at B pillar until the key is removed, or the driver's door is closed and then re-opened.

4. Repeat steps with passenger door.

#### NOTE: If any binding or chattering is noted, lubricate tracks according to "Motorized Track Lubrication" in the "Safety Belts" section of the "Body/Collision Repair Service Manual," or refer to Technical Information Bulletin 92-T-11. Restraint tracks should be lubricated every 6000 miles (9654 km). Sliders (mice) may operate slower in cold weather.

After repairs are made, REPEAT the "Passive Restraint System Performance Test." found in this bulletin.

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.
