Ignition-off draw fuse. Relay and fuse block

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.

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. Removing and installing the IOD fuse again with the ignition 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.

(2) Remove the fuse access panel by unsnapping it from the left outboard end of the instrument panel.

(3) To install the IOD fuse, use a thumb to press the IOD fuse holder unit in fuse cavity 12 firmly into the JB.

(4) Install the fuse access panel by snapping it onto the left outboard end of the instrument panel.

Relay and fuse block

The relay and fuse block is serviced as a unit with the instrument panel wire harness. If any internal circuit of the relay and fuse block or the relay and fuse block housing is faulty or damaged, the entire instrument panel wire harness unit must be replaced.

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

REMOVAL

(1) Disconnect and isolate the battery negative cable.

(2) Remove the instrument panel assembly from the dash panel. Refer to Instrument Panel Assembly in the index of this service manual for the instrument panel assembly removal procedures.

(3) Disconnect each of the instrument panel wire harness connectors. Refer to Connector Locations in the index of this service manual for the location of more information on the instrument panel wire harness connector locations.

(4) Remove all of the fasteners that secure each of the instrument panel wire harness ground eyelets to the instrument panel components. Refer to Connector Locations in the index of this service manual for the location of more information on the ground eyelet locations.

(5) Disengage each of the retainers that secure the instrument panel wire harness to the instrument panel components. Refer to Connector Locations in the index of this service manual for the location of more information on the instrument panel wire harness retainer locations.

(6) Push the relay and fuse block towards the left end of the instrument panel to disengage its mounting slots from the tabs on the Junction Block (JB) (Fig. 11).

(7) Remove the relay and fuse block and the instrument panel wire harness from the instrument panel as a unit.

INSTALLATION

NOTE: If the relay and fuse block is being replaced with a new unit, be certain to transfer each of the fuses, the flasher and the relays from the faulty relay and fuse block to the proper cavities of the replacement relay and fuse block. Refer to Fuse/ Fuse Block in the index of this service manual for the location of complete relay and fuse block circuit diagrams and cavity assignments.

(1) Position the relay and fuse block and the instrument panel wire harness onto the instrument panel.

(2) Install the relay and fuse block by engaging its mounting slots onto the tabs on the Junction Block (JB).

(3) Engage each of the retainers that secure the instrument panel wire harness to the instrument panel components. Refer to Connector Locations in the index of this service manual for the location of more information on the instrument panel wire harness retainer locations.

(4) Install all of the fasteners that secure each of the instrument panel wire harness ground eyelets to the instrument panel components. Refer to Connector Locations in the index of this service manual for the location of more information on the ground eyelet locations.

(5) Reconnect each of the instrument panel wire harness connectors. Refer to Connector Locations in the index of this service manual for the location of more information on the instrument panel wire harness connector locations.

(6) Install the instrument panel assembly onto the dash panel. Refer to Instrument Panel Assembly in the index of this service manual for the location of the instrument panel assembly installation procedures.

(7) Reconnect the battery negative cable.
