PRE-INSPECTION FOR DIAGNOSTIC
Basic InspectionINFOID:0000000005147424
1. CHECK POWER SUPPLY AND DROUND CIRCUIT
Check the power supply and ground circuit as shown below.
• Driver seat control unit: Refer to ADP-47, "
DRIVER SEAT CONTROL UNIT : DiagnosisProcedure".
• Automatic drive positioner control unit: Refer to ADP-48, "
AUTOMATIC DRIVE POSITIONER CONTROL
UNIT : DiagnosisProcedure".
Is the inspection result normal?
YES >> GO TO 2
NO >> Repair or replace the malfunctioning part.
2. CHECK MANUAL FUNCTION
Check the manual function operati ons by operating the relevant switches as shown below.
• Seat (slide, reclining, lifting front, lifting rear)
• Pedal assembly (forward, backward)
• Steering wheel (upward, downward)
• Door mirror
Do all manual functions operate normally?
YES >> GO TO 3
NO (Seat, pedal, door mirror)>>Go to SYMPTOM 1, refer to ADP-169, "
Symptom Table". And, GO TO 4 if
the result of SYMPTOM 1 is OK.
3. CHECK MEMORY FUNCTION 1
Register the seat positions (refer to Owner’s Manual) and check that all parts of the seat, pedals, steering
wheel and door mirrors move to their memory positions correctly.
Are the operations normal?
YES >> Check each malfunction according to the instruction of the SYMPTOM 4, refer to ADP-169,
"Symptom Table".
No (memory indicator operates normally)>> Go to SYMPTOM 2, refer to ADP-169, "
Symptom Table".
No (memory indicator does not operate normally either)>> GO TO 5
4. CHECK MEMORY FUNCTION 2
Register the seat positions (refer to Owner’s Manual) and check that all parts of the seat, pedals, steering
wheel and door mirrors move to their memory positions correctly.
Are the operations normal?
YES >> Check intermittent incident. Refer to GI-38, "Intermittent Incident".
NO >> GO TO 7
5. CHECK SEAT MEMORY SW ITCH/MEMORY INDICATOR
Check the seat memory switch/memory switch indicator of the SYMPTOM 5, refer to ADP-169, "
Symptom
Table".
Is the inspection result normal?
YES >> GO TO 6
NO >> Repair or replace the malfunctioning part.
6. CHECK OPERATION CONDITION
Check the memory operation conditions (refer to ADP-12, "
AUTOMATIC DRIVE POSITIONER SYSTEM :
System Description").
Are all operation conditions fulfilled?
YES >> Go to SYMPTOM 6, refer to ADP-169, "Symptom Table".
NO >> Fulfill the operation conditions. Refer to ADP-12, "
AUTOMATIC DRIVE POSITIONER SYSTEM :
System Description".
7. CHECK MECHANISM
Check for the following.

AUTOMATIC DRIVE POSITIONER SYSTEM
AUTOMATIC DRIVE POSITIONER SYSTEM : System Description
INFOID:0000000005147427
OUTLINE
The system automatically moves the driver seat, pedal assembly, steering wheel and door mirror position by
the driver seat control unit and the automatic drive posit ioner control unit. The driver seat control unit corre-
sponds with the automatic drive positioner control unit by UART communication.
AUTOMATIC DRIVE POSITIONER SYSTEM : Component Parts LocationINFOID:0000000005147426
Function Description
Manual function The driving position (seat, pedal assembly, steering wheel and door mirror position)
can be adjusted by using the power seat switch, pedal adjusting switch, ADP steering
switch or door mirror remote control switch.
Memory function The seat, pedal assembly and outside mirror move to the stored driving position by
pressing seat memory switch (1 or 2).
Entry/Exit assist function Exit On exit, the seat moves backward and the steering wheel moves upward.
Entry
On entry, the seat and steering wheel return from exiting position to the previous driv-
ing position.
