JUNCTION BLOCK

WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.

access panel opening to access and remove the one
screw that secures the Junction Block (JB) to the left
instrument panel end bracket.

(4) Remove the steering column opening cover

from the instrument panel. Refer to Steering Col-
umn Opening Cover in the index of this service
manual for the location of the steering column open-

REMOVAL AND INSTALLATION (Continued)

(5) Reach through the outboard side of the instru-

ment panel steering column opening to access and
disconnect all of the wire harness connectors from
the JB connector receptacles (Fig. 9).

(6) Reach through the outboard side of the instru-

ment panel steering column opening to access and
remove the relay and fuse block from the JB. Push
the relay and fuse block towards the left end of the
instrument panel to disengage its mounting slots
from the tabs on the JB.

(7) Reach through the outboard side of the instru-

ment panel steering column opening to access and
remove the one screw that secures the JB to the left
instrument panel end bracket.

(8) Reach through the outboard side of the instru-

ment panel steering column opening to remove the
JB from the left instrument panel end bracket.

INSTALLATION

NOTE: If the Junction Block (JB) is being replaced
with a new unit, be certain to transfer each of the
fuses, circuit breakers and relays from the faulty JB
to the proper cavities of the replacement JB. Refer
to Junction Block in the index of this service man-
ual for the location of complete circuit diagrams
and cavity assignments for the JB.

(1) Reach through the outboard side of the instru-

ment panel steering column opening to position the
JB onto the left instrument panel end bracket.

(2) Reach through the outboard side of the instru-

ment panel steering column opening to install and
tighten the one screw that secures the JB to the left
instrument panel end bracket. Tighten the screw to
2.2 N·m (20 in. lbs.).

(3) Reach through the outboard side of the instru-

ment panel steering column opening to access and
install the relay and fuse block onto the JB by engag-
ing the relay and fuse block mounting slots with the
tabs on the JB.

(4) Reach through the outboard side of the instru-

ment panel steering column opening to access and
reconnect all of the wire harness connectors to the
JB connector receptacles.

(5) Install the steering column opening cover onto

the instrument panel. Refer to Steering Column
Opening Cover in the index of this service manual
for the location of the steering column opening cover
installation procedures.

(6) Reach through the instrument panel fuse

access panel opening to install and tighten the one
screw that secures the junction block to the left
instrument panel end bracket. Tighten the screw to
2.2 N·m (20 in. lbs.).

(7) Install the fuse access panel by snapping it

onto the left outboard end of the instrument panel.

(8) Reconnect the battery negative cable.

IGNITION-OFF DRAW FUSE

The Ignition-Off Draw (IOD) fuse is disconnected

from Junction Block (JB) fuse cavity 12 (Fig. 10)
when the vehicle is shipped from the assembly plant.
Dealer personnel must reconnect the IOD fuse when
the vehicle is being prepared for delivery in order to
restore full electrical system operation.

REMOVAL AND INSTALLATION (Continued)

NOTE: When removing or installing the IOD fuse, it
is important that the ignition switch be in the Off
position. Failure to place the ignition switch in the
Off position can cause the radio display to become
scrambled when the IOD fuse is installed. Remov-
ing and installing the IOD fuse again with the igni-
tion switch in the Off position will usually correct
the scrambled radio display condition.

REMOVAL

(1) Turn the ignition switch to the Off position.
(2) Remove the fuse access panel by unsnapping it

from the left outboard end of the instrument panel.

(3) Grasp the upper and lower tabs of the IOD

fuse holder unit in fuse cavity 12 of the JB between
the thumb and forefinger and pull the unit firmly
outward.

(4) Install the fuse access panel by snapping it

onto the left outboard end of the instrument panel.

INSTALLATION

(1) Turn the ignition switch to the Off position.
