Inspect the relay and socket terminals to be sure they
are all making good contact.
a lf the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.

lf a test indicates a problem, find and correct
the cause, then recheck the system.- lf all the input tests prove OK, the turn sig-

Wiring Precautions
. Never attempt to modify, splice or repair SRS wiring.
NOTE: SRS wiring can be identified by special yellow
outer protective covering.
. Be sure to install ihe harness wires so that they are not
pinched or interfering with other car parts.
. Make sure all SRS ground locations are clean and
grounds are securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.
Backprobing Spring-loaded Lock
Connectors
. When checking voltage or resistance on this type of
connector the first time, it is necessary to remove the
retainer to insert tester probes from the wire side.
NOTE: lt is not necessary to reinstall the removed
retainer; the terminals will stav locked in the connec-
tor housing.
To remove the retainer, insen a flat tip scrGirdr'\/".
between connector body and retainer, and car"fully
ory out the retarner.
NOTE: Take care not to break the conn€ctor.

Circuit Schematics
Each schematic reoresents one circuit.
A circuit's wires and components are
arranged to show current flow, from
power at the top of the page, to ground,
at the bottom.
Other circuits may share power or ground
terminals or wiring with the circuit shown.
A wire that connects one circuit to
another, lor example, is cut short and has
an arrowhead at the end of it pointing in
the direction of current flow. Next to the
arrowhead is the name ol the circuit or
component which shares that wiring. To
quickly check shared wiring, check the
operation of a component it serves. lf that
component works, you know the shared
wiring is OK.
All connectors are numbered (C709,
C416, etc.). Below each connector
number (except those for components)
is the number of a ohoto in the back
of the book showing the connector's
location on the car. Connector cavities
are also numbered. The numbering
sequence begins at the top left corner
of the connector as seen from eilher of
the viewpoints shown on page E.
Disregard any numbers molded into the
connector housing.
Wires are identif ied by the abbreviated
names of their colors; the second color is
the color of the stripe. Wires are also
identif ied by their location in a connector.
The number "2" next to the male and
female wire terminals at C416, for
example, means those terminals join in
cavity 2 of connector C41 6.
A complete description of schematic
symbols begins on page @.
O,e
Arowhead meanswire connects toanother ciacuit;it points in directionof current tlow.
"OK" note tellsYou how tocheck sharedwiring.

How To Use This Manual
Symbols
Ground - "G"
This symbol means the end of
the wire is attached (grounded) Ito the car frame or to a metal Ipart connected to the f rame. \I orol
,
Each wire ground (G) ," -/numbered for reference.
Q,(Switches
These switches move
together; the broken straight
line between them means thev
are mechanically connected.
Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted, all switches are shown
in their normal (rest) position,
with power off .
This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car f rame or to a metal
part connected to the f rame.
This symbol represents
the bus bar inside a ground
connector. The dots a

is the connection between the
bus bar and metal (grounded)
part of the car.
Terminals - "T"

Solid-state
Fuses
This means power is supplied
when the ignition switch is in ON (ll).
Diodes
A rectifier diode works like a one
way valve. lt allows current to
flow only in the dlrection of the
arrow.
A Zener diode blocks reverse
currenl at normal voltages just like
a rectifier diode. At high voltages,
however, a Zener diode allows
current to flow in reverse.
Q,(
Each 'T" terminal (ring type)
is numbered for reference ano
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interf erence) shielding
around a wire. The
shielding is always
connected to ground.
