Side Marker/Turn Signal/Hazard Flasher System

Description

To cope with dimensional requirements for the airbag components and to offer better operational feel, the turn signal

lever and the cancel mechanism are separated mechanically, and connected electrically instead.

The system cancels the turn signals electrically, by means of a solenoid, after a turn is made. A sensor mechanism which

consists of cancel cams on the steering shaft, and a pair of switches, is used to monitor the steering shaft's position.

Supplemental Restraint System (SRS)
Self-diagnosis Function

The SRS unit includes a self-diagnosis function. If there
is a failure in the sensors, SRS unit, inflator, or their cir-

cuits, the SRS light in the instrument panel goes ON.

SRS INDICATOR LIGHT
As a system check the SRS light also comes on when

the ignition is first turned to the II position. If the light
goes off after approximately 6 seconds, the system is

OK.

If the SRS light remains on (or fails to come on the sys-

tem check mode) one of the SRS components (or the wir-
ing/connectors in-between) is faulty.

Troubleshooting Precautions Always use the test harness. Do not use test
probes directly on component connector
terminals or wires; you may damage them or the
control unit. When connecting any of the test harnesses to the
system, push the connectors straight-in; do not
bend the connector terminals. Before disconnecting any part of the SRS wire
harness, install the short connector (RED) on the airbag. SRS Indicator Light Troubleshooting
Possible conditions: 1. SRS light does not come on at all — see page
23-326.

2. SRS light stays on constantly - see page 23-330.

3. SRS light comes on in combination with a failure of
another electrical system (brake indicator, engine
check light etc.). Check for damage/corrosion at the
dash fuse box.

NOTE:
Before starting the applicable troubleshooting,
check the condition of all SRS connectors and
ground points. If the fault is not found after completing the ap-
plicable troubleshooting, substitute a known-good

SRS unit and check whether the light indication

goes away.
Short connector Installation 1. Disconnect the battery negative cable, then the positive cable.
2. Remove the access panel from the steering wheel, then remove the short connector (RED).
