< BASIC INSPECTION >[HR16DE (WITH EURO-OBD)]
DIAGNOSIS AND REPAIR WORKFLOW
YES >> GO TO 7.
NO >> GO TO 9.
7.PERFORM SPEC IN DATA MONITOR MODE
With CONSULT-III
Make sure that “MAS A/F SE-B1”, “B/FUEL SCHDL” and “A/F ALPHA-B1” are within the SP value using CON-
SULT-III in “SPEC” of “DATA MONITOR” mode. Refer to EC-116, "
Component Function Check".
Is the measurement value within the SP value?
YES >> GO TO 9.
NO >> GO TO 8.
8.DETECT MALFUNCTIONING PART BY TROUBLE DIAGNOSIS - SPECIFICATION VALUE
Detect malfunctioning part according to EC-117, "
Diagnosis Procedure".
Is malfunctioning part detected?
YES >> GO TO 11.
NO >> GO TO 9.
9.DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE
Detect malfunctioning system according to EC-366, "
Symptom Table" based on the confirmed symptom in
step 4, and determine the trouble diagnosis order based on possible causes and symptom.
>> GO TO 10.
10.DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE
Inspect according to Diagnosis Procedure of the system.
NOTE:
The Diagnosis Procedure in EC section described based on open circuit inspection. A short circuit inspection
is also required for the circuit check in the Diagnosis Procedure. For details, refer to Circuit Inspection in GI-
58, "Circuit Inspection".
Is malfunctioning part detected?
YES >> GO TO 11.
NO >> Monitor input data from related sensors or check the voltage of related ECM terminals using CON-
SULT-III. Refer to EC-328, "
Reference Value".
11 .REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is displayed, erase it. Refer to EC-94, "
Diagnosis Description".
>> GO TO 12.
12.FINAL CHECK
When DTC was detected in step 2, perform DTC CONFIRMATION PROCEDURE or Component Function
Check again, and then make sure that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and make sure
that the symptom is not detected.
Is DTC detected and does symptom remain?
YES-1 >> DTC is detected: GO TO 10.
YES-2 >> Symptom remains: GO TO 6.
NO >> Before returning the vehicle to the customer, make sure to erase unnecessary DTC in ECM.
(Refer to EC-94, "
Diagnosis Description".) If the completion of SRT is needed, drive vehicle under
the specific DRIVING PATTERN in EC-363, "
HowtoSetSRTCode".
