GENERAL INFORMATION

INTRODUCTION

Operating instructions for the factory installed audio systems can be found in the Owner’s Manual provided with the vehicle.
The vehicles are equipped with an Interior (Igni­tion Off Draw) fuse in the Power Distribution Center located in the engine compartment. After the Interior (IOD) fuse or battery has been disconnected the clock will require resetting.
NOTE: This group covers both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) versions of this model. Whenever required and feasible, the RHD versions of affected vehicle components have been constructed as mirror-image of the LHD versions. While most of the illustrations used in this group represent only the LHD version, the diagnostic and service procedures outlined can generally be applied to either version. Exceptions to this rule have been clearly identified as LHD, RHD, or Export if a special illustration or procedure is required.

to suppress ignition noise which may interfere with radio reception.
• Left engine mount clip on strap
• Engine to shock tower reinforcement
Inductive type spark plug cables in the high ten­sion circuit of the ignition system complete the inter­ference suppression. Faulty or deteriorated spark plug wires should be replaced.
DIAGNOSIS AND TESTING

AUDIO DIAGNOSTIC TEST PROCEDURES

CAUTION: The CD player will only operate between approximate temperatures of -23°C and +65°C (-10°F and +145°F).
Whenever a radio malfunction occurs;
(1) First check FUSES:
(a) Power Distribution Center (PDC), Interior
lamp fuse, M1 - Radio Memory Feed
(b) Fuse Block:
(I) Fuse 12, Illumination in the fuse block (II) Fuse 16, Ignition feed in the fuse block
DESCRIPTION AND OPERATION

INTERFERENCE ELIMINATION

The radio utilizes a ground wire plugged on to a blade terminal and is bolted to the radio chassis. Both connector and terminal should be securely attached. The engine has two separate ground straps
NOTE: The vehicles are shipped with the INTERIOR LAMP fuse disconnected.
(2) Verify, the radio wire harness are properly con­nected before starting normal diagnosis and repair procedures. Refer to Audio Diagnostic Charts and/or Group 8W, Wiring Diagrams, Radio Section.

TESTING

The antenna has a short cable which connects into the instrument panel harness. The connection is made on the right side of the instrument panel.
Antenna performance may be tested by substitut­ing a known good antenna. It is also possible to check short or open circuits with an ohmmeter or continuity light once the antenna cable is discon­nected from the radio as follows:
(1) Continuity should be present between the antenna mast and radio end pin of antenna cable plug (Fig. 1).
(2) No continuity should be observed or a very high resistance of several megohms between the ground shell of the connector and radio end pin.
(3) Continuity should be observed between the ground shell of the connector and the mounting hard­ware on the vehicle antenna. The wheel well splash shield must be removed for access to the antenna that is mounted on load beam.
bracket. Wiggle cable over its entire length to
reveal intermittent short or open circuits dur­ing step 1, 2 and 3.

It is also possible to check short or open circuits with an ohmmeter or continuity light once the antenna has been removed from the vehicle.
(1) Continuity should be present between the tip of the mast and radio lead in (Fig. 2).
(2) No continuity should be observed or a very high resistance of several megohms between the ground shell of the connector and radio end pin.
(3) Continuity should be observed between the ground shell of the connector and the mounting

REMOVAL

(1) Remove antenna mast by unscrewing mast
from antenna body (Fig. 3), or (Fig. 4).
(2) Locate the antenna lead disconnect in the instrument panel wire harness above the right kick panel. Disconnect the antenna cable from cable lead.
(3) Unfasten push pins from the rear of the plastic inner fender shield and move shield to gain access to mounting screws (Fig. 5).
(4) Remove mounting screw and remove antenna base and cable assembly from under the fender.

INSTALLATION

(1) Align antenna adapter tongue with grove in the fender hole and push adapter into fender.
(2) From under the fender, push the antenna base and cable assembly through the adapter in the fender. Tighten mounting screw to 7 N·m (75 in. lbs.).
(3) Seat the grommet in the side panel and con­nect the cable to the instrument panel harness con­nector.
(4) Install the plastic inner fender shield.
