DETAILED FLOW
1.INTERVIEW FROM THE CUSTOMER
Clarify customer complaints before inspection. First of all, perform an interview utilizing STC-20, "Diagnostic
Work Sheet" and reproduce symptoms to understand them fully. A sk customer about his/her complaints care-
fully. Check symptoms by driving v ehicle with customer, if necessary.
CAUTION:
Customers are not professional. Never make assumpti ons like “maybe the customer means that...,” or
“maybe the customer mentioned this symptom”.
>> GO TO 2.
2.CHECK SYMPTOM
Reproduce the symptom that is indicated by the cu stomer, based on the information from the customer
obtained by interview. Also check that the symptom is not caused by protection function. Refer to STC-12,
"Protection Function".
CAUTION:
When the symptom is caused by normal operation, fully inspect each portion and obtain the under-
standing of customer that the symptom is not caused by a malfunction.
>> GO TO 3.
3.CHECK VEHICLE CONDITION
With CONSULT
1. Turn ignition switch ON.
2. Check “C/U TEMP“ and “C/U TEMP A“ in “DATA MONITOR“ of “EPS“.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Wait with the ignition switch OFF until the data monitor indication becomes 90 °C (194 °F) or less.
Go to 4 after the temperature drops to 90 °C (194 °F) or less.
4.PERFORM SELF-DIAGNOSIS
With CONSULT
Perform self-diagnosis.
Is any DTC detected?
YES >> Record or print DTC and freeze frame data (FFD). GO TO 5.
NO >> GO TO 7.
5.RECHECK SYMPTOM
With CONSULT
1. Erase self-diagnostic results for “EPS”.
2. Perform DTC confirmation procedures for the malfunctioning system.
NOTE:
If some DTCs are detected at the same time, determine the order for performing the diagnosis based on STC-
13, "DTC Inspection Priority Chart".
Is any DTC detected?
Monitor item Values
C/U TEMP 90 °C (194 °F) or less
C/U TEMP A 90 °C (194 °F) or less

DIAGNOSIS AND REPAIR WORK FLOW
YES >> GO TO 6.
NO >> Check harness and connectors based on the information obtained by interview.
6.REPAIR OR REPLACE THE MALFUNCTIONING COMPONENTS.
• Repair or replace the malfunctioning components.
• Reconnect part or connector after repairing or replacing.
• When DTC is detected, erase self-diagnostic results for “EPS”.
>> GO TO 8.
7.IDENTIFY THE MALFUNCTIONING SYSTEM BY SYMPTOM DIAGNOSIS
Estimate the malfunctioning system based on symptom diagnosis and perform inspection.
Can the malfunctioning system be identified?
YES >> GO TO 8.
NO >> Check harness and connectors based on the information obtained by interview.
8.FINAL CHECK
With CONSULT
1. Check the reference value for power steering control module.
2. Recheck the symptom and check that sympto m is not reproduced on the same conditions.
Is the symptom reproduced?
YES >> GO TO 3.
NO >> Inspection End.
Diagnostic Work SheetINFOID:0000000009460355
Description
• In general, customers have their own criteria for a pr oblem. Therefore, it is important to understand the
symptom and status well enough by asking the customer about his/her concerns carefully. To systemize all
the information for the diagnosis, prepare the interview sheet referring to the interview points.
• In some cases, multiple conditions that appear simultaneously may cause a DTC to be detected.
