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 (Igni-
tion 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.
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 three separate ground
straps to suppress ignition noise which may interfere
with radio reception.
²Left engine mount clip on strap
²Engine to shock tower reinforcement
²Rear strut to body, clip-on strap
Inductive type spark plug cables in the high ten-
sion circuit of the ignition system complete the inter-
ference suppression. Faulty or deteriorated spark
plug wires should be replaced.
In addition, there is a capacitor mounted on the
cylinder head which also helps suppress ignition
noise.
DIAGNOSIS AND TESTING
AUDIO DIAGNOSTIC TEST PROCEDURES
