ii) Problem Symptom Confirmation
Check if what the customer claimed in CUSTOMER QUESTIONNAIRE is actually found in the vehicle and
if that symptom is found, whether it is identified as a failure. (This step should be shared with the customer
if possible.) When “ABS” warning light is not operated correctly, proceed to “Table-A or B”.
iii) Diagnostic Trouble Code (DTC) Check, Record and Clearance
Perform “Diagnostic Trouble Code Check” procedure in this section, record it and then clear it referring to
“Diagnostic Trouble Code Clearance” in this section.
If the malfunction DTC which was once displayed and then cleared cannot be detected (indicated) again
when the ignition switch is turned ON, attempt to diagnose the trouble based on the DTC recorded in this
step may mislead the diagnosis or make diagnosing difficult. Proceed to Step 2 to check control module for
proper self-diagnosis function.
If the malfunction DTC which was once displayed and then cleared can be detected (indicated) again when
ignition switch is turned ON, proceed to Step 3.
2. DRIVING TEST
Test drive the vehicle at 40 km/h for more than a minute and check if any trouble symptom (such as abnormal
lighting of “ABS” warning light) exists.
If the malfunction DTC is confirmed again at ignition switch ON, driving test as described in above is not neces-
sary. Proceed to Step 3.
3. DIAGNOSTIC TROUBLE CODE CHECK
Recheck diagnostic trouble code referring to item “DTC CHECK” as shown in the following page.
4. DIAGNOSTIC TROUBLE CODE FLOW CHART
According to Diagnostic flow table for the diagnostic trouble code confirmation in Step 3, locate the cause of
the trouble, namely in a sensor, switch, wire harness, connector, actuator assembly or other part and repair or
replace faulty parts.
5. “DIAGNOSIS” IN “BRAKE” SECTION
Check the parts or system suspected as a possible cause referring to “Diagnosis” in “BRAKE” section and based
on symptoms appearing on the vehicle (symptom obtained through Steps 1-i, 1-ii and 2 and repair or replace
faulty parts, if any).
6. CHECK FOR INTERMITTENT PROBLEM
Check parts where and intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to IN-
TERMITTENT TROUBLE in “GENERAL INFORMATION” section and related circuit of trouble code recorded
in Step 1-iii.
7. FINAL CONFIRMATION TEST
Confirm that the problem symptom has gone and the ABS is free from any abnormal conditions. If what has been
repaired is related to the malfunction DTC, clear the DTC once and perform test driving and confirm that no DTC
is indicated.
