DIAGNOSIS AND REPAIR WORKFLOW

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) using the “Diagnostic Work Sheet”. (Refer to

EC-539, "Diagnostic Work

Sheet"

.)

>> GO TO 2.

2.

CHECK DTC

1.

Check DTC.

2.

Perform the following procedure if DTC is displayed.

-

Record DTC and freeze frame data. (Print them out with CONSULT-III or GST.)

-

Erase DTC.

-

Study the relationship between the cause detected by DTC and the symptom described by the customer.
(Symptom Table is useful. Refer to

EC-795, "Symptom Table"

.)

3.

Check related service bulletins for information.

Is any symptom described and is any DTC detected?

Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.
Symptom is not described, DTC is detected>>GO TO 5.

3.

CONFIRM THE SYMPTOM

Try to confirm the symptom described by the customer (except MI ON).
Also study the normal operation and fail safe related to the symptom. Refer to

EC-800, "Description"

and

EC-

519, "Fail Safe"

.

Diagnostic Work Sheet is useful to verify the incident.
Verify relation between the symptom and the condition when the symptom is detected.

>> GO TO 5.

4.

CONFIRM THE SYMPTOM

Try to confirm the symptom described by the customer.
Also study the normal operation and fail safe related to the symptom. Refer to

EC-800, "Description"

and

EC-

519, "Fail Safe"

.

Diagnostic Work Sheet is useful to verify the incident.
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 make sure that DTC is
detected again.
If two or more DTCs are detected, refer to

EC-521, "DTC Inspection Priority Chart"

and determine trouble

diagnosis order.
NOTE:
• Freeze frame data is useful if the DTC is not detected.
• Perform Component Function Check if DTC CONFIRMATION PROCEDURE is not included on Service

Manual. This simplified check procedure is an effective alternative though DTC cannot be detected during
this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC CONFIR-
MATION PROCEDURE.

Is DTC detected?

YES

>> GO TO 10.

NO

>> Check according to

GI-42, "Intermittent Incident"

.

6.

PERFORM BASIC INSPECTION

Perform

EC-547, "Work Procedure"

.

Do you have CONSULT-III?

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 in “SPEC”
of “DATA MONITOR” mode with CONSULT-III. Refer to

EC-558, "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-559, "Diagnosis Procedure"

.

YES

>> GO TO 11.

NO

>> GO TO 9.

9.

DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE

Detect malfunctioning system according to

EC-795, "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

GI-44, "Circuit Inspec-

tion"

.

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-508, "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.

>> 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. If the

completion of SRT is needed, drive vehicle under the specific “DRIVING PATTERN” in

EC-554,

"SRT Set Driving Pattern"

.

DIAGNOSIS AND REPAIR WORKFLOW

There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about an incident. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the WORKSHEET SAMPLE
below in order to organize all the information for troubleshooting.
Some conditions may cause the MI to come on steady or blink and
DTC to be detected. Examples:
Vehicle ran out of fuel, which caused the engine to misfire.
