Some electrical components which require
a large amount of current to operate
use a special switch called a relay. Sinc e these circuits carry a large amount of
current, the thickness of the wire in the ci rcuit is also greater. If this large wire
were connected from the load to the c ontrol switch, the switch would have to
carry the high amperage load and the fair ing or dash would be twice as large to
accommodate the increased size of t he wiring harness. To prevent these
problems, a relay is used.
Relays are composed of a coil and a se t of contacts. When the coil has a
current passed though it, a magnetic fiel d is formed and this field causes the
contacts to move together, completing the circuit. Most relays are normally
open, preventing current from passing thr ough the circuit, but they can take any
electrical form depending on th e job they are intended to do. Relays can be
considered "remote control switches." They allow a smaller current to operate
devices that require higher amperages. W hen a small current operates the coil,
a larger current is allo wed to pass by the contacts. Some common circuits
which may use relays are the horn, headlight s, starter, electric fuel pump and
other high draw circuits.

Fig. 3: Relays are composed of a coil and a switch. These two components are
linked together so that w hen one operates, the other operat es at the same time.
The large wires in the circuit are connect ed from the battery to one side of the
relay switch (B+) and from the opposite side of the re lay switch to the load
(component). Smaller wires are connected from the relay coil to the control
switch for the circuit and from the opposite side of the relay coil to ground
LOAD
Every electrical circuit must include a "load" (something to use the electricity
coming from the source). Without this l oad, the battery would attempt to deliver
its entire power supply from one pole to another. This is called a "short circuit."
All this electricity would take a short cut to ground and cause a great amount of
damage to other components in the circui t by developing a tremendous amount
of heat. This condition could develop suffici ent heat to melt the insulation on all
the surrounding wires and reduce a multiple wire cable to a lump of plastic and
copper.

SERVICE PRECAUTIONS
The DERM can maintain sufficient volt age to cause a deployment for up to 10
minutes after the ignition switch is tur ned OFF or the battery is disconnected.
Always disable the system when perfo rming service procedures ON OR NEAR
the system and it's components.
CAUTION - The disarming and arming procedures must be followed in the
order listed to temporarily disable the SI R system. Failure to do so could result
in possible air bag deployment, pers onal injury or otherwise unneeded SIR
system repairs.
DISARMING THE SYSTEM
1. Turn the steering wheel so that t he vehicle's wheels are pointing straight
ahead.
2. Turn the ignition switch to the LOCK position.
3. Remove the SIR or AIR BAG fuse from the fuse panel.
4. Remove the left side trim panel, t hen remove the Connector Position
Assurance (CPA) device and disconnec t the yellow two-way SIR harness
connector at the base of the steering column.
5. On vehicles with passenger side air bags, remove the glove box door
then disconnect the yellow two-way c onnector located near the yellow
24-way DERM harness connector.
With the fuse removed and the ignition sw itch ON, the air bag warning lamp will
be on. This is normal and does not indicate a SIR system malfunction.

BLOWER SWITCH

With the control head removed from t
he vehicle, the blower switch may be
removed by pulling the blower switch knob off and removing the retaining clip or
retaining screws.

VACUUM MOTORS
OPERATION
Used on certain heating and air condition ing systems, the vacuum actuators
operate the air doors determining the differ ent modes. The actuator consists of
a spring loaded diaphragm connec ted to a lever. When vacuum is applied to the
diaphragm, the lever moves t he control door to its appropriate position. When
the lever on the control panel is moved to another position, vacuum is cut off
and the spring returns the actuator lever to its normal position.
TESTING 1. Disconnect the vacuum line from the actuator.
2. Attach a hand held vacuum pump to the actuator.
3. Apply vacuum to the actuator.
4. The actuator lever should move to its engaged position and remain there
while vacuum is applied.
5. When vacuum is released it should move back to its normal position.
6. The lever should operat e smoothly and not bind.
REMOVAL & INSTALLATION 1. Remove the vacuum li nes from the actuator.
2. Disconnect the linkage from the actuator.
3. Remove the hardware attaching the actuator.
4. Remove the actuator.
To install: 5. Install the actuator and attaching hardware.
6. Connect the linkage to the actuator.
7. Connect the vacuum lines to the actuator.
8. Test system to confirm proper functioning of the actuator.

Federal law requires that the
odometer in any replacement
speedometer/odometer must r egister the same mileage as that registered on
the removed speedometer/odometer. Service replacement
speedometer/odometers and odometer modul es with the mileage preset to
actual vehicle mileage are available through the dealer. In nearly all cases, the
mileage continues to accumu late in the odometer memory even if the odometer
does not display mileage. Th is mileage can usually be verified by the dealer.
Contact the dealer for instructi ons to receive a replacement
speedometer/odometer with pres et mileage. If the actual vehicle mileage cannot
be verified, the dealer will supply a spe edometer/odometer with a display set to
zero miles. In addition, an odometer mileage sticker is supplied with the
replacement odometer. The sticker must display the estimated vehicle mileage
and is to be affixed to the driver's door.
REMOVAL & INSTALLATION 1. The gauges can be removed from the cluster assembly by: a. Removing the cluster lens.
b. Removing the printed circuit board from the back of the cluster.
c. Removing the gauge attaching screws.
2. Installation is the reverse of removal.
SPEEDOMETER CABLE
REMOVAL & INSTALLATION 1. Disconnect the negative batte ry cable at the battery.
2. On models without cruise control, disconnect the speedometer cable
strap at the power brake booster. On models with cruise control,
disconnect the speedometer cable at the cruise control transducer.
3. Remove the instrument cluster trim plate.
4. Remove the instrument cluster a ttaching screws and pull the cluster out
far enough to gain access to the r ear of the speedometer head.
5. Reach beneath the c able connection at the speedometer head, push in
on the cable retaining spring, and disconnect the cable from the
speedometer.
6. Slide the old cable ou t of the speedometer cable casing. If the cable is
broken, remove the cable from both ends of the casing. Using a short
piece of the old cable to fit t he speedometer connection, turn the
speedometer to increase the speed i ndicated on the dial and check for
any binding during rotation. If binding is noted, the speedometer must be
removed for repair or replacement. Check the entire cable casing for
extreme bends, chafing, breaks, et c., and replace if necessary.
To install: 7. Wipe the cable clean us ing a lint free cloth.
8. If the old casing is to be reused, flush the casing with petroleum spirits
and blow dry with compressed air.
