safe".
CAUTION:
When the symptom is caused by normal operation, fully inspect each portion and obtain the under-
standing of customer that the sympt om is not caused by a malfunction.
>> GO TO 3.
3.PERFORM THE SELF-DIAGNOSIS
With CONSULT-III.
Perform self-diagnosis for “ABS”.
Is DTC detected?
YES >> Record or print self-diagnosis results. GO TO 4.
NO >> GO TO 6.
4.RECHECK THE SYMPTOM
With CONSULT-III.
1. Erase self-diagnostic results for “ABS”.
2. Perform DTC confirmation procedures for the error-detected system. NOTE:
If some DTCs are detected at the some time, det ermine the order for performing the diagnosis based on
BRC-50, "
DTC Inspection Priority Chart" [ABS actuator and electric unit (control unit)].
Is any DTC detected?
YES >> GO TO 5.
NO >> Check harness and connectors based on the information obtained by interview. Refer to GI-40,
"Intermittent Incident".
5.REPAIR OR REPLACE ERROR-DETECTED PART
Repair or replace error-detected parts.
Reconnect part or connector after repairing or replacing.
When DTC is detected, erase self-diagnostic result for “ABS”.
>> GO TO 7.
6.IDENTIFY ERROR-DETECTED S YSTEM BY SYMPTOM DIAGNOSIS
Estimate error-detected system based on symptom diagnosis and perform inspection.
Can the error-detected system be identified?

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 in terview sheet referring to the interview points.
In some cases, multiple conditions that appear simultaneously may cause a DTC to be detected.
