NOTE:
When diagnosis sensor unit is replaced with new one, “AIR BAG”
warning lamp will operate in User mode. Checking “AIR BAG”
warning lamp operation in Diagnosis mode is not required. Go to
step 6.
5. If “AIR BAG” warning lamp operates as shown in No. 1 in chart
above, turn ignition switch “OFF” to reset from Diagnosis mode
to User mode and to erase the memory of the malfunction.
Then go to step 6.
If “AIR BAG” 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-60, and repair mal-
functioning part completely.
6. Turn ignition switch “ON”. “AIR BAG” warning lamp operates in
User mode. Compare “AIR BAG” 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 “ON”.
2) After “AIR BAG” warning lamp lights for 7 seconds, turn igni-
tion switch “OFF” within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch “ON”.
SRS is now in User mode.

STARTING SYSTEM
System Description
SC-13

System DescriptionNJSC0009The 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. 39, 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 100A 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 30
Ground is supplied to terminal 18 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 sufficient volt-
age 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.GI
