Trouble Diagnosis with Battery/Starting/Charging System TesterAKS0079K
NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and alternator test segments must be done
as a set from start to finish.
1. Turn off all loads on the vehicle electrical system.
2. Perform battery and starting system test with Battery/Starting/
Charging system tester.
3. Press “ENTER” to begin the charging system test.
4. Start engine.
5. Press “ENTER” until “LOADS OFF REV ENGINE 5 SEC” is dis-
played.
6. Raise and hold the engine speed at 1,500 to 2,000 rpm for about
5 seconds, then return the engine to idle.
Once the increase in engine rpm is detected, press “ENTER” to
continue.
NOTE:

If after 30 seconds an increase in engine idle speed is not
detected, “RPM NOT DETECTED” will display.

Some engines may have a higher idle initially after starting,
particularly when the engine is cold. The tester may detect
this without any other action being taken. If this occurs, con-
tinue on with the testing process. The final results will not be affected.
7. The tester now checks the engine at idle and performs the
DIODE/RIPPLE check.
8. When complete, the tester will prompt you to turn on the follow-
ing electrical loads.

Heater fan set to highest speed. Do not run the A/C or wind-
shield defroster.

Headlamp high beam

Rear window defogger
NOTE:
Do not run the windshield wipers or any other cyclical loads.
9. Press “ENTER” to continue.

10. Raise and hold the engine speed at 1,500 to 2,000 rpm for about
5 seconds, then return the engine to idle. Once the increase in
engine rpm is detected, press “ENTER” to continue.
NOTE:
If after 30 seconds an increase in engine idle speed is not
detected, “RPM NOT DETECTED” will be displayed. Press
“ENTER” to restart the test.
11. Diagnostic result is displayed on the tester. Refer to SC-27,
"DIAGNOSTIC RESULT ITEM CHART" .
12. Press “ENTER” then test output code is displayed. Record the
test output code on the repair order.
13. Toggle back to the “DIAGNOSTIC SCREEN” for test results.

AUTOMATIC DRIVE POSITIONERPFP:28491
System Description AIS002XB

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

The settings (ON/OFF) of the automatic sliding seat (Entry/Exiting operation) at entry/exit can be changed
as desired, using the display unit in the center of the instrument panel. The set content is transmitted by
CAN communication, from display unit (without NAVI) or display control unit (with NAVI) to driver seat con-
trol unit.

Using CONSULT-II, the seat slide amount at entry/exit setting can be changed.
MANUAL OPERATION
The driving position [seat position, steering wheel position (tilt, telescopic) and door mirror position] can be
adjusted with the power seat switch or ADP steering switch or door mirror remote control switch.
NOTE:

The seat can be manually operated with the ignition switch OFF.

The door mirrors can be manually operated with the ignition switch turned ACC or ON.
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, return 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.
MEMORY STORING AND KEY FOB INTERLOCK STORING

Store the 2 driving positions and shifts to the stored driving position with the memory switch.
Function Description
Memory switch operation The seat, steering and door mirror move to the stored driving position by pushing
memory switch (1 or 2).
Entry/Exiting functionExiting operation At exit, the seat moves backward and steering wheel moves forward/upward.
Entry operationAt entry, the seat and steering wheel returns from the exiting position to the previous
driving position.
Key fob interlock operationPerform memory operation, exiting operation and entry operation by pressing key fob
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 selector lever is in any position other than P.

When the door mirror remote control switch is operated (when ignition switch turned to
ON or ACC).

When power seat switch turned ON.

When ADP steering switch turned ON (telescopic operation or tilt operation).

When door mirror operates (only memory switch operation).

When driver seat sliding Entry/Exiting setting is OFF (only entry/exiting operation).

When steering wheel tilt and telescopic Entry/Exiting setting is OFF (only entry/exiting
operation).

When the tilt and telescopic sensor malfunction is detected.

Check continuity between the automatic drive positioner control unit connector M50 terminal 40 (B), 48 (B)
and ground.
OK or NG
OK >> Driver seat control unit circuit is OK.
NG >> Repair or replace harness between automatic drive
positioner control unit and ground.
CONSULT-II FunctionAIS002YF
The following functions are performed by combining data received and command transmitted via the commu-
nication line from the driver seat control unit.
*1: For setting automatic drive positioner functions only.
*2: Refer to BL-40, "
Data Monitor" .
*3: During vehicle driving, do not perform active test.
CONSULT-II INSPECTION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch “OFF”.
2. Connect “CONSULT-II” and “CONSULT-II CONVERTER” to the
data link connector.
3. Turn ignition switch “ON”.40 (B) – Ground : Continuity should exist.
48 (B) – Ground : Continuity should exist.
