Key-reminder warning
L0 Battery voltage is always supplied, through
fusible link No. 6 to the key-reminder switch.
l When the driver’s seat is opened while the
ignition key is still in the key cylinder, the door
switch is switched ON, electricity flows to
fusible link No. 6, the key-reminder switch, the
buzzer, the door switch, and ground, and the
buzzer sounds.
Seat belt warning
lBattery voltage is applied, through fuse No. 11
to the ETACS unit when the ignition key is at the
“ON” position.
l Electricity flows to fusible link No. 6, the seat
belt warning light, the ETACS unit, and ground,
and the seat belt warning light flashes for
approx. 6 seconds.
lIf the driver does not buckle the seat belt, the
seat belt switch is switched ON, electricity
flows to fusible link No. 6, the key-reminder
switch, the buzzer, the seat belt switch, the
ETACS unit, and ground, and the buzzer sounds
for approx. 6 seconds.
lWhen the driver buckles the seat belt, the seat
belt switch is switched OFF and the buzzer
stops.

1. Check the SRS fuses (multi-purpose fuses No. 11 and No.
18).If either is loose, tighten it; if damaged or blown, replace it.
.
2.After performing step 1, start engine. Does “SRS” warning
light
illumi.nate for about 7 seconds and then turn OFF? If
yes, SRS system is functioning properly.
If no, continue with following steps.
NOTEIf the battery power supply (multi-purpose fuses No. 11 or
No. 18) is disconnected with the ignition key in the “ON”
position, the SRS warning light will continue to illuminate
even after the fuses are replaced in their original positions.
In this case, the SRS warning light can be extinguished by
turning the ignition switch ON and OFF
10 times.
3. Turn the ignition key to the “LOCK” position.
4. Insert ROM pack into the Multi-use Tester and connect
tester to Diagnosis Check Connector in glove compart-
ment.
5. Start the SRS diagnosis,by conducting TEST 1
(SRSwarninq liqht does not extinguish) or TEST 2 (SRS warning
light does- not illuminate.) which begins on next page or

A double-lock mechanism is employed for the connec-
tor of the SRS diagnosis unit, so care must be taken notto damage it by using excessive force or by not
. .disconnecting it correctly.(4) Disconnect the red

(1) Turn the ignition key to the “LOCK” position, disconnect
the negative battery cable and tape the terminal.
Caution
Wait at least 30 seconds after disconnecting the battery
cable before doing any further work. The SRS system is
designed to retain enough voltage to deploy the air bagfor a short time even after the battery has been
disconnected, so serious injury may result from unin-
tended air bag deployment if work is done on the SRSsystem immediately after the battery cable is discon-
nected.(2) Remove the rear console assembly. (Refer to GROUP 52A
- Floor Console.)
(3) Use a screwdriver to push in the lock spring of the lock
lever of the SRS diagnosis unit to unlock the lock lever.
