KNOCK SENSOR
DESCRIPTION
The knock sensor threads into the cylinder block.
The knock sensor is designed to detect engine vibra-
tion that is caused by detonation.
OPERATION
When the knock sensor detects a knock in one of
the cylinders, it sends an input signal to the PCM. In
response, the PCM retards ignition timing for all cyl-
inders by a scheduled amount.
Knock sensors contain a piezoelectric material
which constantly vibrates and sends an input voltage
(signal) to the PCM while the engine operates. As the
intensity of the crystal's vibration increases, the
knock sensor output voltage also increases.
The voltage signal produced by the knock sensor
increases with the amplitude of vibration. The PCM
receives as an input the knock sensor voltage signal.
If the signal rises above a predetermined level, the
PCM will store that value in memory and retard
ignition timing to reduce engine knock. If the knock
sensor voltage exceeds a preset value, the PCM
retards ignition timing for all cylinders. It is not a
selective cylinder retard.
The PCM ignores knock sensor input during engine
idle conditions. Once the engine speed exceeds a
specified value, knock retard is allowed.
Knock retard uses its own short term and long
term memory program.
Long term memory stores previous detonation
information in its battery-backed RAM. The maxi-
mum authority that long term memory has over tim-
ing retard can be calibrated.
Short term memory is allowed to retard timing up
to a preset amount under all operating conditions (aslong as rpm is above the minimum rpm) except WOT.
The PCM, using short term memory, can respond
quickly to retard timing when engine knock is
detected. Short term memory is lost any time the
ignition key is turned off.
NOTE: Over or under tightening affects knock sen-
sor performance, possibly causing improper spark
control.

OCCUPANT RESTRAINT
CONTROLLER
DESCRIPTION
The front driver and passenger airbag system is
designed to reduce the risk of fatality or serious
injury, caused by a frontal impact of the vehicle.
The Occupant Restraint Controller (ORC) contains
the impact sensor and energy reserve capacitor. It is
mounted on a bracket, under the instrument panel,just forward of the storage bin. The ORC monitors
the system to determine the system readiness. The
ORC contains on-board diagnostics and will light the
AIRBAG warning lamp in the message center when a
problem occurs.
OPERATION
The impact sensor provides verification of the
direction and severity of the impact. One impact sen-
sor is used. It is located inside the Occupant
Restraint Controller (ORC). The impact sensor is an
accelerometer that senses deceleration. The decelera-
tion pulses are sent to a microprocessor which con-
tains a decision algorithm. When an impact is severe
enough to require airbag protection, the ORC micro-
processor sends a signal that completes the electrical
circuit to the driver and passenger airbags. The
impact sensor is calibrated for the specific vehicle
and reacts to the severity and direction of an impact.
REMOVAL
NOTE: Diagnose the ORC using the service/diag-
nostic manual.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove storage bin from instrument panel.
Refer to Body, Instrument Panel, Storage Bin,
Removal.
(3) Remove three bolts holding ORC to floor
bracket.
(4) Disconnect the wire connector from ORC.
(5) Remove the ORC assembly from vehicle.
INSTALLATION
WARNING: DO NOT INSTALL ORC IF MOUNTING
LOCATION IS DEFORMED OR DAMAGED.
CAUTION: Use correct screws when installing the
ORC.
(1) Install the ORC assembly into vehicle.
(2) Connect the wire connector to the ORC.
(3) Install three bolts holding ORC to floor
bracket. Torque bolts to 7.3 - 9.6 N´m (65 to 85 in.
lbs.)
(4) Install the storage bin onto the instrument
panel. Refer to Body, Instrument Panel, Storage Bin,
Installation.
WARNING: DO NOT CONNECT THE BATTERY NEG-
ATIVE CABLE. REFER TO ELECTRICAL,

PASSENGER AIRBAG
DESCRIPTION
WARNING: NEVER DISASSEMBLE THE PASSEN-
GER AIRBAG, THE PASSENGER AIRBAG HAS NO
SERVICEABLE PARTS.
The Passenger Airbag is located beneath the
instrument panel and pad assembly. The airbag is
mounted to the back side of the instrument panel
reinforcement.
The instrument panel top pad is the most visible
part of the passenger airbag system. Located under
the instrument panel top pad are the airbag door, the
passenger airbag cushion and the airbag cushion
supporting components.
The passenger airbag includes a magnesium hous-
ing within which the cushion and inflator are
mounted and sealed.
Following a passenger airbag deployment, the pas-
senger airbag and the instrument panel must be
replaced. The passenger airbag cannot be repaired,
and must be replaced if deployed or damaged in any
way.
OPERATION
The passenger airbag is equipped with two infla-
tors, each with three levels of pressure output. The
inflators seal the hole in the airbag cushion so it can
discharge the gas it produces directly into the cush-
ion when supplied with the proper electrical signal.
Following an airbag deployment, the airbag cushion
quickly deflates by venting this gas through the
cushion material towards the instrument panel.
The passenger airbag is secured with screws to the
instrument panel beneath the instrument panel top
pad and above the glove box opening. The instrument
panel top pad above the glove box opening conceals
the airbag door and a predetermined hinge line
beneath its decorative cover. Upon airbag deploy-
ment, the top pad will bend at the hinge line and the
door will fold back out of the way onto the top of the
instrument panel.
When the front airbag system is deployed, the fol-
lowingMUSTbe replaced:
²Complete Steering Column Assembly.
²Lower Steering Column Coupler.
²Steering Wheel.
²Clock Spring.
²Driver Airbag.
²Passenger Airbag.
²Upper Instrument Panel with Pad.
CARE OF UNDEPLOYED AIRBAGS
Airbags must be stored in their original special
container until used for service. At no time should a
source of electricity be permitted near the inflator on
the back of an airbag. When carrying or handling an
undeployed airbag, the trim side of the airbag should
be pointing away from the body to minimize possibil-
ity of injury if accidental deployment occurs. Do not
place undeployed airbag face down on a solid surface,
the airbag will propel into the air if accidental
deployment occurs.
STANDARD PROCEDURE - CLEAN UP
Roll or fold the passenger airbag towards the
instrument panel surface and close the door over the
folded bag. Then tape the door shut.
Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in to avoid kneeling or sitting in a contaminated
area. Vacuum the heater and A/C outlets as well. If
HVAC was in RECIRC mode at time of airbag
deployment, operate HVAC blower on low speed/heat
and vacuum powder residue expelled from the heat
outlets. Multiple vacuum cleaning may be necessary
to decontaminate the interior of the vehicle.
