DESCRIPTION

The passive restraint control module (PRCM), located in the console, controls the power for the passive restraint belt system and the lap and shoulder belt reminder system.

OPERATION

The passive restraint system operates according to a built in logic that allows independent operation of both front shoulder belts. The following information explains when the belts are driven to the A pillar or "B" pillar, and what conditions must be present to allow operation of the passive restraint system.

The PRCM controls shoulder belt operation according to conditions detected by the PRCM through inputs received from various switches (door switches, limit switches, key reminder switch, and ignition switch). The PRCM receives these signals and operates the shoulder belts according to its internal program. The following information explains how the PRCM operates the shoulder belts, according to different operating conditions the PRCM will encounter.

NORMAL

The shoulder belt moves to the "B" pillar when the ignition is ON and the door is closed, or the vehicle speed exceeds 13 mph.

The shoulder belt moves to the "A" pillar when the door opens and the vehicle speed is less than 13 mph.

For the driver's side only, the shoulder belt moves to the "A" pillar if the ignition is off and the key is out of the ignition.

DEFAULT STATE

If the ignition is off, the driver's shoulder belt at the "A" pillar and a door opens on one side of the vehicle to wake up the PRCM, the shoulder belt for the other door remains at the present location.

SECOND ATTEMPT

If a shoulder belt is unable to reach the destination determined by the PRCM, another attempt is made as soon as the vehicle speed exceeds 13 mph.

RESPONSE TO A FAILED DOOR SWITCH

If vehicle speed exceeds 13 mph with a door open, or the door switch failed, indicating an open door, the PRCM will attempt to driver the shoulder belt to the "B" pillar. The shoulder belt will not be driven to "A" pillar until at least one of the following conditions are met

  1. Vehicle speed is less than 13 mph, and the door switch has cycled indicating door closure, then cycled indicating door opening.
  2. Ignition is off, and the door switch indicates the door is open.
  3. For driver's side shoulder belt only, the ignition is off, and the ignition key has been removed from the ignition switch.

HIGH SPEED DECELERATION

If a door opens within three seconds of a rapid vehicle deceleration, the shoulder belt remains at the "B" pillar one of the following conditions are met

  1. Vehicle speed is less than 13 mph, and the door switch has cycled indicating door closure, then cycled indicating door opening.
  2. Ignition is off, and the door switch indicates the door is open.
  3. For driver's side shoulder belt only, the ignition is off, and the ignition key has been removed from the ignition switch.

If an apparent rapid deceleration occurs due to turning the ignition off (which terminates the vehicle speed pulses), the belts will not move for the next three seconds, even if a door opens.

The deceleration condition causing the responses specified above must be such that vehicle speed decreases from a speed above 13 mph to a speed below 13 mph in a rapid manner.

MOTOR SHUTDOWN

When a pillar switch opens indicating the belt has reached its destination, the module de-energizes the belt motor.

STALL TIME-OUT

If a belt motor has been energized for more than 15 seconds, the PRCM will de-energize the motor.

DELAYED ON BELT MOTION REVERSAL

If the belt is moving towards a selected destination and the destination changes while the belt is in motion, the PRCM will de-energize the motor for 0.5 seconds before energizing the motor in the opposite direction.

RESPONSE TO FAILED PILLAR LIMIT SWITCHES

The PRCM determines if a limit switch fails so that the belt appears to be at both pillars simultaneously. So, no matter which destination is selected, the PRCM will energize the motor for 15 seconds to drive the belt toward the selected destination. The PRCM determines the selected destination according to received inputs and its own internal program.

INDICATOR LAMP

The passive restraint system has an audible and visual indicator and reminder system.

A shoulder belt indicator lamp (Red, with ISO symbol) is activated when any of the following conditions are detected.

  1. If either shoulder belt is not at the "B" pillar.
  2. If the driver's shoulder belt is unbuckled.
  3. If the PRCM detects that either pillar switch has failed in a manner indicating that the shoulder belt is always at the location of a failed switch.

If the indicator lamp is on due to an unbuckled shoulder belt, buckling the shoulder belt terminates the Red indicator lamp.

A lap belt indicator lamp (Red, Lap Belt) is activated as follows

  1. The indicator lamp is lit continuously for 2 seconds as a bulb check when the ignition is switched from OFF to ON.
  2. If the driver's lap belt is not buckled, the indicator lamp will start to flash four to six seconds after the driver's shoulder belt starts moving towards the "B" pillar or six seconds after the ignition is switched from OFF to ON with the driver's shoulder belt at the "B" pillar. After flashing for 10 seconds, the lamp stay on solid
  3. If a once buckled lap belt is unbuckled, the lamp will flash for 10 seconds then stay on solid.

AUDIBLE REMINDER

An audible reminder (five chimes over eight seconds) occurs as follows

  1. If four seconds or more have elapsed since the driver's shoulder belt started moving toward the "B" pillar, or since the ignition has been switched from OFF to ON, and the driver's shoulder belt is unbuckled.

If the audible warning is due to an unbuckled shoulder belt and/or lap belt, buckling the shoulder belt and/or lap belt terminates the audible alarm.

Lap belt and shoulder belt reminders (indicate lamps and audible chime) terminate if the driver's side belt destination is the "A" pillar.

SHOULDER BELT RETRACTOR/POWER PASSIVE RESTRAINT TRACK SYSTEM INTERACTION

Shoulder retractors that connect to the motorized slider (located in the center console) are vehicle sensitive and will lock if the vehicle exceeds a 17 degree angle or 0.6g of deceleration forces. 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 front retractors will unlock when 1/4 inch (6.35mm) 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 1/4 inch (6.35mm) of belt to be fed back into the shoulder belt retractor.

* PLEASE READ FIRST *

Before checking each ground circuit from the component all the way to the ground stud, check the circuit from the splice pack to ground by testing some of the other sub-systems grounded by the same splice pack.
