INSPECTION
Magnetic Switch Check

Before starting to check, disconnect the battery cable from the negative terminal.

Disconnect “M” terminal of starter motor.
1. Continuity test (between “S” terminal and switch body).

No continuity... Replace.
2. Continuity test (between “S” terminal and “M” terminal).

No continuity... Replace.
Pinion/Clutch Check
1. Inspect pinion teeth.

Replace pinion if teeth are worn or damaged. (Also check
condition of ring gear teeth.)
2. Inspect reduction gear teeth (If equipped).

Replace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)
3. Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.

If it locks or rotates in both directions, or unusual resistance is
evident... Replace.
Brush Check
BRUSH

Check wear of brush.
–Excessive wear... Replace.

CHARGING SYSTEMPFP:23100
System DescriptionBKS001MJ
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:

through 10A fuse (No. 36, located in the fuse and fusible link block)

to alternator terminal 4 (“S” terminal).
“B” terminal 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” terminal) detecting the input voltage.
The charging circuit is protected by the 120A fusible link (letter A, located in the fusible link holder).
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. 14, located in the fuse block (J/B)]

to combination meter terminal 8 for the charge warning lamp.
Ground is supplied:

to combination meter terminal 22

through alternator terminal 3 (“L” terminal)

to alternator terminal “E”

through ground E2.
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.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate charge warning lamp, if any of the following symp-
toms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.

Trouble DiagnosisBKS001ML
Before performing an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspection
Table.

Before starting, inspect the fusible link.

Use fully charged battery.
WITH IC REGULATOR
NOTE:

If the inspection result is OK even though the charging system is malfunctioning, check the “B” terminal
connection (Check the tightening torque) and voltage drop.

Check condition of rotor coil, rotor slip ring, brush and stator coil. If necessary, replace malfunctioning
parts with new ones.

AUTOMATIC DRIVE POSITIONER

AUTOMATIC DRIVE POSITIONERPFP:28491
System Description BIS0012G

The system automatically moves the driver seat to facilitate entry/exit to/from the vehicle. The automatic
drive positioner control unit can also store the optimum driving positions (driver seat) for 2 people. If the
driver is changes, one-touch operation allows changing to the other driving position.

Using CONSULT-II, the seat slide amount at entry/exit setting can be changed.
MANUAL OPERATION
The driving position (seat position) can be adjusted with the power seat switch.
NOTE:
The seat can be manually operated with the ignition switch OFF.
A U T O M AT I C O P E R AT I O N
NOTE:

Disconnecting the battery erases the stored memory.

After connecting the battery, insert the key into the ignition cylinder and turn the driver door switch ON (open)→OFF (close)→ON
(open), the Entry/ Exiting operation becomes possible.

After exiting operation is carried out, entry operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON→START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes.Function Description
Memory switch operation The seat move to the stored driving position by pushing memory switch (1 or 2).
Entry/Exiting functionExiting operation At exit, the seat moves backward.
Entry operation At entry, the seat returns from the exiting position to the previous driving position.
Keyfob interlock operation Perform memory operation and exiting operation by pressing keyfob unlock button.
Auto operation temporary stop
conditions.When ignition switch turned to START during memory switch operation and return opera-
tion, memory switch operation and entry operation is stopped.
Auto operation stop conditions.

When the vehicle speed becomes 7 km/h (4 MPH) or higher.

When the setting switch, memory switch 1, or 2 are pressed.

When A/T or CVT selector lever is in any position other than P.

When power seat switch turned ON.
