5 Does SRS warning light come on?
PREPARATION:
(a) Disconnect negative (−) terminal cable from the battery.
(b) Connect center airbag sensor assembly connector.
(c) Connect negative (−) terminal cable to battery, and wait
at least 2 seconds.
(d) Turn ignition switch to ACC or ON.
CHECK:
Check operation of SRS warning light.
OK:
SRS warning light comes on.
NO Check terminal LA of center airbag sensor
assembly. If normal, replace center airbag
sensor assembly.
YES
From results of above inspection, malfunctioning part can now be considered normal. To make
sure of this, use simulation method to check.
6 Is new ECU−B fuse burnt out again?
NO Using simulation method, reproduce
malfunction symptoms. (See page IN−16)
YES
Check harness between ECU−B fuse and
SRS warning light.

INSPECTION PROCEDURE
If DTC is not displayed, do following troubleshooting:
1 Does SRS warning light up for approx. 6 seconds?
PREPARATION:
Check operation of SRS warning light after ignition switch is
turned from LOCK position to ACC or ON position.
NO Check SRS warning light system (See page
DI−365).
YES
2 Check voltage between terminals Tc and E1 of DLC1.
PREPARATION:
Turn ignition switch to ACC or ON.
CHECK:
Measure voltage between terminals Tc and E1 of DLC1.
OK:
Voltage: 10 − 16 V
OK Go to step 4.

4 Check center airbag sensor assembly.
PREPARATION:
(a) Turn ignition switch to LOCK.
(b) Disconnect negative (−) terminal cable from the battery,
and wait at least 90 seconds.
(c) Remove steering wheel pad (See page SR−13 or
SR−26).
(d) Disconnect center airbag sensor assembly connector.
(e) Insert service wire into terminal Tc from back side as
shown.
(f) Connect center airbag sensor assembly connector with
service wire.
(g) Connect negative (−) terminal cable to battery.
(h) Turn ignition switch to ACC or ON, and wait at least 20 se-
conds.
(i) Connect service wire of terminal Tc to body ground.
CHECK:
Check operation of SRS warning light.
OK:
SRS waning light comes on.
NOTICE:
Never make a mistake with the terminal connection posi-
tion as this cause a malfunction.
OK Check harness between center airbag sensor
assembly and DLC1.
NG
Replace center airbag sensor assembly.

(b) Using a belt tension gauge, check the drive belt tension.
Belt tension gauge:
Nippondenso BTG 20 (95506−00020) or
Borroughs No. BT−33−73F
Drive belt tension:
New belt
175 ± 5 lbf
Used belt
115 ± 20 lbf
If necessary, adjust the drive belt tension.
HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing the drive belt, check that it fits properly in
the ribbed grooves. Check with your hand to confirm that
the belt has not slipped out of the groove on the bottom
of the crank pulley.
After installing a new belt, run the engine for approx. 5
minutes and then recheck the tension.
7. VISUALLY CHECK GENERATOR WIRING AND LIS-
TEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
8. INSPECT DISCHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ON. Check that the discharge
warning light comes on.
(b) Start the engine. Check that the light goes off.
If the light does not operate as specified, troubleshoot the dis-
charge warning light circuit.
9. CHECK CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit according to the manufacturers instruc-
tions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:
Disconnect the wire from terminal B of the generator
and connect the wire to the negative (−) terminal of
the ammeter.
