depressed, the Low position is selected and the high
position LED indicator illuminates. When the right
side of the switch rocker is fully depressed, the High
position is selected and the low position LED indica-
tor illuminates. When the switch rocker is moved to
its neutral position (middle), Off is selected and both
LED indicators are extinguished.
Both switches provide separate resistor multi-
plexed hard wire inputs to the BCM to indicate the
selected switch position. The BCM monitors the
switch inputs and sends heated seat switch status
messages to the Heated Seat Module (HSM) or the
Memory Heated Seat Module (MHSM) over the Pro-
grammable Communications Interface (PCI) data
bus. The HSM or MHSM responds to the heated seat
switch status messages by controlling the output to
the seat heater elements of the selected seat. The
Low heat position set point is about 36É C (97É F),
and the High heat position set point is about 41É C
(105É F).

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 (as
long 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.

MULTI-FUNCTION SWITCH
DESCRIPTION - TURN SIGNAL SYSTEM
The turn signals are actuated with a lever on
Multi-Function Switch, located on the left side of the
steering wheel. The signals are automatically turned
off by a canceling cam (two lobes molded to the clock
spring mechanism). The cam comes in contact with
the cancel actuator on the turn signal (multi-func-
tion) switch assembly. Either cam lobe, pushing on
the cancel actuator, returns the switch to the OFF
position. The multi-function switch is a resistive
MUX switch that feeds inputs to the BCM.

CLOCK SPRING
DESCRIPTION
The clock spring is screwed to a plastic mounting
platform on the steering column behind the steering
wheel. The clock spring is used to maintain a contin-
uous electrical circuit between the wiring harness
and the drivers airbag.
OPERATION
This assembly consists of a flat ribbon like electri-
cally conductive tape which winds and unwinds with
the steering wheel rotation. The clock spring cannot
be repaired. If the clock spring is faulty, damaged, or
if the airbag has been deployed, the clock spring
must be replaced.
STANDARD PROCEDURE - CLOCK SPRING

DRIVER AIRBAG
DESCRIPTION
The Driver Airbag is located in the center of the
steering wheel. The most visible part of the airbag is
the cover/horn switch.
OPERATION
The Driver Airbag cover contains the horn switch,
inflator device, and a fabric bag. The airbag cover/
horn switch is serviced separately from the inflator
and bag components.
WHEN THE FRONT AIRBAG SYSTEM IS
DEPLOYED BECAUSE OF A COLLISION, THE
FOLLOWING MUST BE REPLACED:
²COMPLETE STEERING COLUMN ASSEMBLY
²LOWER STEERING COUPLER
²STEERING WHEEL
²STEERING COLUMN CLOCK 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 - DEPLOYED DRIVER
AIRBAG CLEAN UP
Roll or fold the driver airbag towards the steering
wheel and then tape the bag to the steering wheel.
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.
SERVICE OF DEPLOYED AIRBAG
