DIAGNOSIS AND REPAIR WORKFLOW
1. GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2
2. CHECK DTC WITH AUTOMATIC DRIVE POSITIONER SYSTEM
Check “Self Diagnostic Result” with CONSULT-III.
Refer to ADP-127, "DTC Index"
.
Is any symptom described and any DTC is displayed?
Symptom is described, DTC is displayed.>>GO TO 3
Symptom is not described, DTC is displayed.>>GO TO 7
Symptom is described, DTC is not displayed.>>GO TO 4
3. CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
>> GO TO 7
4. CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
>> GO TO 5
5. CHECK NORMAL OPERATING CONDITION
Check normal operating condition. Refer to ADP-161, "Description"
.
Is the incident normal operation?
YES >> Inspection End.
NO >> GO TO 6
6. PERFORM BASIC INSPECTION
Isolate the malfunctioning point with the basic inspection. Refer to ADP-8, "Preliminary Check"
.
>> GO TO 8
7. PERFORM DTC CONFIRMATION PROCEDURE
Perform the confirmation procedure for the detected DTC.
Is the DTC displayed?
YES >> GO TO 9
NO >> Check intermittent incident. Refer to GI-38, "Intermittent Incident"
.
8. PERFORM COMPONENT FUNCTION CHECK
Perform the component function check for the isolated malfunctioning point.
>> GO TO 9
9. DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Isolate the malfunctioning point by performing the di agnosis procedure relevant to the symptom during the
component diagnosis.
>> GO TO 10
10. REPAIR OR REPLACE
Repair or replace the malfunctioning part.

PRE-INSPECTION FOR DIAGNOSTIC
Basic InspectionINFOID:0000000004055281
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 : Diagnosis Procedure"
.
 Automatic drive positioner control unit: Refer to ADP-47, "AUTOMATIC DRIVE POSITIONER CONTROL
UNIT : Diagnosis Procedure".
Is the inspection result normally?
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-159, "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-159,
"Symptom Table".
No (memory indicator operates normally)>> Go to SYMPTOM 2, refer to ADP-159, "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-159, "Symptom
Table".
Is the inspection result normal?
YES >> GO TO 6
NO >> Repair or replace the malfunctioning part.
6. CHECK OPERATION CONDITION
