DETAILED FLOW
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
Is any symptom described and any DTC detected? Symptom is described, DTC is displayed>>GO TO 3.
Symptom is described, DTC is not displayed>>GO TO 4.
Symptom is not described, DTC is displayed>>GO TO 5.
3.CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT to the vehicle in “DATA MONITOR” mode and check real time diagnosis results.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 5.
4.CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT to the vehicle in “DATA MONITOR ” mode and check real time diagnosis results.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 6.
5.PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC Confirmation Procedure for the displayed DTC, and then check that DTC is detected again.
At this time, always connect CONSULT to the vehicle, and check diagnostic results in real time.
If two or more DTCs are detected, refer to BCS-107, "DTC Inspection Priority Chart" and determine trouble diagnosis order.
NOTE:
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC Confirmation Procedure.
Is DTC detected? Yes >> GO TO 7.
No >> Refer to GI-41, "Intermittent Incident".
6.DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE
Detect malfunctioning system according to SYMPTOM TABLE based on the confirmed symptom in step 4, and determine the trouble diagnosis order based on possible causes and symptom.
>> GO TO 7.
7.DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
NOTE: The Diagnostic Procedure described based on open circuit inspection. A short circuit inspection is also required for the circuit check in the Diagnostic Procedure. Is malfunctioning part detected? YES >> GO TO 8.
NO >> Check voltage of related BCM terminals using CONSULT.
8.REPAIR OR REPLACE THE MALFUNCTIONING PART
>> GO TO 9.
9.FINAL CHECK
When DTC was detected in step 2, perform DTC Confirmation Procedure or Component Function Check again, and then check that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and check that the symptom is not detected.
Is the inspection result normal? NO (DTC is detected)>>GO TO 7.
NO (Symptom remains)>>GO TO 6.
YES >> Inspection End.

DTC Description
DTC DETECTION LOGIC
The heated oxygen sensor 2 has a much longer switching time between rich and
lean than the air fuel ratio (A/
F) sensor 1. The oxygen storage capacity of the three way catalyst (manifold)
causes the longer switching
time.
