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-46, 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 on the next page.
NOTE:
When a malfunction is detected, switch from Diagnosis mode
to user mode by turning the ignition switch as follows:

System Description
M/T MODELS
Power is supplied at all times
Ithrough 40A fusible link (letterC, located in the fuse and fusible link box)
Ito ignition switch terminal 1.
With the ignition switch in START position, power is supplied
Ifrom ignition switch terminal 1
Ito starter motor harness connector terminal 4.
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
SC-13

System Description
The 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:
I10A fuse (No. 31, 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 (ZD30DDTi engine models). The
charging circuit is protected by the 100A (A/T models) fusible link.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
Ithrough 10A fuse [No. 12, located in the fuse block (J/B)]
Ito combination meter terminal 28 for the charge warning lamp.
Ground is supplied to terminal 2 of the combination meter through terminal 1(L) (TD27Ti engine models) or
3(L) (ZD30DDTi engine model) 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 malfunction is indicated.
