The following procedure is for replacement of a
faulty or damaged front outboard seat belt and
retractor unit, which includes a seat belt tensioner
for this model. (Refer to 8 - ELECTRICAL/RE-
STRAINTS/SEAT BELT TENSIONER - DESCRIP-
TION). The only component of this seat belt and
retractor unit that is available for individual service
replacement is the plastic web stop button that pre-
vents the latch plate from falling to the floor while in
the stored position. Refer to the instructions supplied
with the service kit for the proper web stop button
replacement procedures.
The seat belt retractor on the driver's side of stan-
dard cab models only also includes a tension reducer.
(Refer to 8 - ELECTRICAL/RESTRAINTS/TENSION
REDUCER - DESCRIPTION). The seat belt retractor
on the passenger's side of all models includes a swit-
chable automatic locking mechanism. (Refer to 8 -
ELECTRICAL/RESTRAINTS/AUTOMATIC LOCK-
ING RETRACTOR - DESCRIPTION).
If the seat belt or retractor is faulty or damaged,
but the seat belt tensioner is not deployed, review
the recommended procedures for handling non-de-
ployed supplemental restraints. (Refer to 8 - ELEC-
TRICAL/RESTRAINTS - STANDARD PROCEDURE
- HANDLING NON-DEPLOYED SUPPLEMENTAL
RESTRAINTS). If the seat belt tensioner has been
deployed, review the recommended procedures for
service after a supplemental restraint deployment
before removing the front outboard seat belt and
retractor from the vehicle. (Refer to 8 - ELECTRI-
CAL/RESTRAINTS - STANDARD PROCEDURE -SERVICE AFTER A SUPPLEMENTAL RESTRAINT

PASSENGER AIRBAG ON/OFF
SWITCH
DESCRIPTION
The passenger airbag on/off switch is standard
equipment on all standard cab versions of this model
when they are equipped with the dual front airbag
system (Fig. 39). This switch is a two-position, resis-
tor multiplexed switch with a single integral red
Light-Emitting Diode (LED), and a non-coded key
cylinder-type actuator. The switch is located in the
lower right corner of instrument panel center bezel,
near the center of instrument panel to make the Off
indicator visible to all front seat occupants. When the
switch is in its installed position, the only compo-
nents visible through the dedicated opening of the
cluster bezel are the switch face plate and nomencla-
ture, and the key cylinder actuator. The9Off9position
of the switch is illuminated when this switch position
is selected, while the ªOnº position of the switch is
designated by text imprinted upon the face plate of
the switch, but is not illuminated. The remainder of
the switch is concealed behind the switch face plate
and the instrument panel center bezel.

OPERATION
The seat belt tension reducer is controlled by a
ground signal received from the seat belt switch on
the seat belt switch sense circuit and a battery cur-
rent signal received from the ignition switch on the
fused ignition switch output (run-accessory) circuit.
When the seat belt switch is closed (the driver side
front seat belt is fastened) and the ignition switch is
in the On or Accessory positions, the seat belt tension
reducer solenoid is energized. When the solenoid is
energized, it actuates a mechanism within the driver
side front outboard seat belt retractor to reduce the
normal recoil spring tension exerted by the retractor
spool, which is designed to reel in the seat belt web-
bing onto the spool. When the driver side seat belt is
unbuckled or if the ignition switch is turned to any
position except On or Accessory, the tension reducer
solenoid is de-energized and the normal recoil spring
tension of the retractor is restored.
The action of the seat belt tension reducer results
in improved seat belt comfort for the driver. Reducing
the seat belt retractor recoil spring tension is desir-
able on standard cab models of this vehicle and not
on the quad cab model due to the different mounting
position required for the seat belt turning loop on the
B-pillar relative to the driver's seat position on the
standard cab model. The seat belt tension reducer
may be diagnosed using conventional diagnostic tools
and methods.
DIAGNOSIS AND TESTING - SEAT BELT

Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.

BEFORE PERFORMING FURTHER DIAGNOSIS OR
SERVICE. THIS IS THE ONLY SURE WAY TO DIS-

FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOY-
MENT.(1) Disconnect and isolate the battery negative
cable. Disconnect the body wire harness connector for
the seat belt tension reducer from the tension
reducer connector receptacle on the driver side front
outboard seat belt and retractor unit. Using an ohm-
meter, measure the resistance between the seat belt
switch sense circuit terminal pin and the fused igni-
tion switch output (run-accessory) circuit terminal
pin in the tension reducer connector receptacle on
the retractor. Resistance through the tension reducer
solenoid coil should be 53 ohms at 20É C (68É F). If
OK, go to Step 2. If not OK, replace the faulty driver
side front outboard seat belt and retractor unit.
(2) Check for continuity between the seat belt
switch sense circuit cavity of the body wire harness
connector for the seat belt tension reducer and a good
ground. There should be continuity with the driver
side front seat belt buckled, and no continuity with
the driver side front seat belt unbuckled. If OK, go to
Step 3. If not OK, repair the shorted or open seat
belt switch sense circuit between the tension reducer
and the seat belt switch as required.
(3) Reconnect the battery negative cable. Check for
battery current at the fused ignition switch output
(run-accessory) circuit of the body wire harness con-
nector for the seat belt tension reducer. There should
be battery current with the ignition switch in the On
or Accessory positions, and no battery current with
the ignition switch in any other position. If not OK,
repair the shorted or open fused ignition switch out-
put (run-accessory) circuit between the tension
reducer and the ignition switch as required.

SWITCH
DESCRIPTION
Two separate switch pods operate the speed control
system. The steering-wheel-mounted switches use
multiplexed circuits to provide inputs to the PCM (to
the ECM for diesel) for ON, OFF, RESUME, ACCEL-
ERATE, SET, DECEL and CANCEL modes. Refer to
the owner's manual for more information on speed
control switch functions and setting procedures.
The individual switches cannot be repaired. If one
switch fails, the entire switch module must be
replaced.
Depending on engine control computer (JTEC
having a 3± plug connector or NGC having a 4±
plug connector), 2 types of switches are used.
Both types of switches are internally and exter-
nally different. The switch used with the NGC
system has an attached pigtail lead. The switch
used with the JTEC system does not have an
attached pigtail lead.
OPERATION
When speed control is selected by depressing the
ON, OFF switch, the PCM(ECM for diesel)allows
a set speed to be stored in its RAM for speed control.
To store a set speed, depress the SET switch while
the vehicle is moving at a speed between approxi-
mately 35 and 85 mph. In order for the speed control

²The VSS signal increases at a rate of 10 mph

between the road surface and tires is extremely low)
²Depressing the clutch pedal (manual trans.).
²Excessive engine rpm (indicates that the trans-
mission may be in a low gear)
²The VSS signal decreases at a rate of 10 mph
per second (indicates that the vehicle may have
decelerated at an extremely high rate)
²If the actual speed is not within 20 mph of the
set speed
