CAUTION1.DO not repair, splice or modify SRS wiring (except for specific repairs to the body wiring harness shown on page QB-14
2.replace wiring if necessary, after reading and following all precautions and procedures in this manual.DO not use an analogue ohmmeter to check SRS wiring or components; use only special tools and digital multi-metershown on page 52B-16.

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
page
[52B-191.

(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.
Caution
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.

TROUBLESHOOTING PROCEDUREd
(1) Check that the air ducts and rods are not off.
(2) Check that connectors are properly connected and fuses are not blown.
(3) Using an analog voltmeter or multi-use tester, check diagnosis outputs. If failure code is being output,
check the failing system and repair as necessary. (Refer to Diagnosis Display Patterns and Codes on
P.55-55.)
(4) If the diagnosis outputs are normal, check for terminal voltage or continuity with a circuit tester accordingto the troubleshooting chart by symptom. (Refer to control unit terminal voltages on
P.55-45 - 52.)
(5) In carrying out the troubleshooting procedure, first look up the Troubleshooting Quick-Reference Chart toknow the inspection items and then start the
insoection orocedure detailed in the following pages.
(6) When checking components, be sure to disconnect the connectors first.
