GENERAL INFORMATION

The Battery, Starting, and Charging Systems oper­
ate with one another, and therefore, must be thor­
oughly tested as a complete system. In order for the
vehicle to start and charge properly, it must have a
battery that will perform to specifications. The starter
motor, generator, wiring, and electronics also must
perform within specifications. Group 8A covers Start­ ing (Fig. 1) and Charging (Fig. 2) System diagnostic
procedures. These procedures include the most basic
conventional methods to On-Board Diagnostics (OBD)
built into the Powertrain Control Module (PCM).
Use of an ammeter, volt/ohmmeter, battery
charger, carbon pile rheostat (load tester), and 12
volt test light will be required.
All OBD sensing systems are monitored by the
PCM. The PCM will store in memory any detectable
failure in the monitored circuits. Refer to Using On-
Board Diagnostic System in this group for more in­ formation.

GENERAL
INFORMATION
Electrically-operated remote control mirrors are
available as an option on D-body vehicles. The mir­
rors are controlled by a single switch assembly lo­
cated on the instrument panel to the right of the
headlamp switch (Fig. 1). D-body vehicles use a toggle-type switch. The
switch is rotated clockwise (Right mirror) or counter­
clockwise (Left mirror) for mirror selection. The
switch is moved UP, DOWN, RIGHT, or LEFT for
mirror movement direction. The motors which operate the mirrors are part of
the mirror assembly and cannot be serviced sepa­
rately.

TEST
PROCEDURES

MIRROR MOTOR TEST PROCEDURE
(1) Remove power mirror switch from mounting
position (refer to Service Procedures). (2) Disconnect wiring harness at switch connector.
(3) Use 2 jumper wires. Connect one to a
12-volt

source, and the other to a good body ground. Refer to
the MIRROR TEST CHART for wire hookups at the switch connector (harness side, not switch side), (4) If results shown in chart are not obtained,
check for broken or shorted circuit, or replace mirror assembly as necessary. MIRROR

WIRE CODE
IDENTIFICATION

Each wire shown in the diagrams contains a code
(Fig. 3) which identifies the main circuit, part of the
main circuit, gauge of wire, and color. The color is shown as a two letter code which can be identified by
referring to the Wire Color Code Chart (Fig. 4). If
the wire has a tracer and it is a standard color an asterisk will follow the main wire color. If the tracer
is non-standard the main wire color will have a slash (/) after it followed by the tracer color. 18

To locate a system or component in the diagrams,
refer to the alphabetical index at the front of the di­ agrams. Determine the diagram sheet number. Sheet
numbers are located at the lower right or left hand
corner of each sheet. Page numbers at the top of
the page do not apply to diagram sheets. The diagram index identifies the main system and
all components that relate to that system. There are
also sections of the index that identify specific com­
ponents only (for example modules, lamps, etc.). Re-
