IEach connector number shown in the wiring dia-
gram corresponds to that in the wiring harness.
The location of each connector in the actual
vehicle is determined by reading the first character
of the connector (for example, a ªFº for F8, ªiº for
i16, etc.) and the type of wiring harness.
The first character of each connector number
refers to the area or system of the vehicle.

2. Basic Diagnostics
Procedures
A: BASIC PROCEDURE
1. GENERAL
The most important purpose of diagnostics is to
determine which part is malfunctioning quickly, to
save time and labor.
2. IDENTIFICATION OF TROUBLE
SYMPTOM
Determine what the problem is based on the symp-
tom.
3. PROBABLE CAUSE OF TROUBLE
Look at the wiring diagram and check the system's
circuit. Then check the switch, relay, fuse, ground,
etc.
4. LOCATION AND REPAIR OF TROUBLE
1) Using the diagnostics narrow down the causes.
2) If necessary, use a voltmeter, ohmmeter, etc.
3) Before replacing certain component parts
(switch, relay, etc.), check the power supply,
ground, for open wiring harness, poor connectors,
etc. If no problems are encountered, check the
component parts.
5. CONFIRMATION OF SYSTEM
OPERATION
After repairing, ensure that the system operates
properly.
B: INSPECTION
1. VOLTAGE MEASUREMENT
1) Using a voltmeter, connect the negative lead to
a good ground point or negative battery terminal
and the positive lead to the connector or compo-
nent terminal.
2) Contact the positive probe of the voltmeter on
connector (A).
The voltmeter will indicate a voltage.
