Seat Belts - Passive Restraint System Diagnostics
BULLETIN NO.: 93-T-02ISSUE DATE: January, 1993
GROUP/SEQ. NO.: Electrical-01
CORPORATION NO.: 281605
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 (1/4 in.) 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.
If system performance is not verified, continue to the "Passive Restraint Diagnosis" charts above.
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.
