Turn SignallHazard Flasher System
1.
Turn Signal/Hazard Relay Input Test
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section {24} before performing repairs or ser-
vice.
Remove the turn signal/hazard relay from the under-
dash fuse/relay box.
Inspect the relay and fuse/relay box socket terminals
to be sure they are all making good contact.
. lf the terminals are bent, loose or corroded,
repair them as necessary, and recheck the system.
. lf the terminals look OK, make the following
input tests at the fuse/relay box socket.- lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.- lf all the input tests prove OK, the turn signal/
hazard relay must be faulty; replace it.

How the Circuit Works
Seat Belt Warning
With the ignition switch in ON (ll) or START (lll),
battery voltage is applied to the seat belt reminder
light. When the seat belt is not buckled, the seat
belt reminder/key-on beeper circuit in the
integrated control unit senses ground through the
closed seat belt switch. The seat belt reminder light
comes on and stays on, and the beeper beeps for
6 seconds. The reminder light and beeper will stop
when the seat belt is buckled or the timer circuit
deactivates them.
lgnition Key Warning
Battery voltage is supplied at all times to the seat
belt reminder/key-on beeper circuit in the
integrated control unit. When you turn on the
ignition key switch the integrated control unit
senses ground. lf you open the driver's door, the
door switch closes, causing the beeper to sound
until the door is closed.
Refer to the Service Manual (Section 23, Electrical)
for specitic tests or troubleshootrng procedures.
