NOTE:
When diagnosis sensor unit is replaced with new one, ªAIR BAGº
warning lamp will operate in User mode. Checking ªAIR BAGº
warning lamp operation in Diagnosis mode is not required. Go to
step 6.
5. If ªAIR BAGº warning lamp operates as shown in No. 1 in chart
above, turn ignition switch ªOFFº to reset from Diagnosis mode
to User mode and to erase the memory of the malfunction.
Then go to step 6.
If ªAIR BAGº warning lamp operates as shown in No. 2 or No.
3 in chart above, the malfunctioning part is not repaired
completely, or another malfunctioning part is detected. Go to
DIAGNOSTIC PROCEDURE 6, page RS-74, and repair mal-
functioning part completely.
6. Turn ignition switch ªONº. ªAIR BAGº warning lamp operates in
User mode. Compare ªAIR BAGº warning lamp operation to
the chart below.
NOTE:
When a malfunction is detected, switch from Diagnosis mode to
user mode by turning the ignition switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn igni-
tion switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch ªONº.
SRS is now in User mode.

System DescriptionNJSC0004M/T MODELSNJSC0004S01Power is supplied at all times
+through 40A fusible link (letterB, located in the fuse and fusible link box)
+to ignition switch terminal 1.
With the ignition switch in START position, power is supplied
+from ignition switch terminal 5
+to starter motor harness connector terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the engine
starts.

STARTING SYSTEM
System Description
SC-13

System DescriptionNJSC0009SEDANNJSC0009S01The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to alternator terminal 4 (S) through:
+10A fuse (No. 33, located in the fuse and fusible link box).
Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage
is controlled by the IC regulator at terminal 4 (S) detecting the input voltage. The charging circuit is protected
by the 80A (A/T models with QG13DE engine and M/T models with gasoline engine) or 100A (A/T models
except QG13DE engine and diesel engine models) fusible link.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
+through 10A fuse [No. 30, located in the fuse block (J/B)]
+to combination meter terminal 17 (Models with tachometer) or 22 (Models without tachometer) for the
charge warning lamp.
Ground is supplied to terminal 62 (Models with tachometer) or 61 (Models without tachometer) of the combi-
nation meter through terminal 3 (L) of the alternator. With power and ground supplied, the charge warning lamp
will illuminate. When the alternator is providing sufficient voltage with the engine running, the ground is opened
and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a fault is indicated.

Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage
is controlled by the IC regulator at terminal 4 (S) detecting the input voltage. The charging circuit is protected
by the 80A (Gasoline engine models without daytime light system) or 100A (A/T models, diesel engine mod-
els and gasoline engine models with daytime light system) fusible link.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
+through 10A fuse [No. 30, located in the fuse block (J/B)]
+to combination meter terminal 40 or 1
Ground is supplied to terminal 1 or 28 of the combination meter through terminal 3 (L) of the alternator. With
power and ground supplied, the charge warning lamp will illuminate. When the alternator is providing suffi-
cient voltage with the engine running, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a fault is indicated.
