DIAGNOSIS AND REPAIR WORKFLOW

DETAILED FLOW

GET INFORMATION FOR SYMPTOM

1. 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-746, "Diagnostic

Work Sheet"

2. Ask if the customer requests I/M examination.

Malfunction information, obtained>>GO TO 2.

No malfunction information, but a request for I/M examination>>GO TO 13.

CHECK DTC

1. Check DTC.

2. Perform the following procedure if DTC is displayed.

Record DTC and freeze frame data. (Print them out using CONSULT or GST.)

Erase DTC.
With CONSULT: “How to Erase DTC and 1st Trip DTC” in

EC-667, "CONSULT Function"

Study the relationship between the cause detected by DTC and the symptom described by the customer.

(Symptom Table is useful. Refer to

EC-1242, "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.

CONFIRM THE SYMPTOM

Try to confirm the symptom described by the customer (except MIL ON).

Also study the normal operation and fail safe related to the symptom. Refer to

EC-1249, "Description"

and

EC-

699, "Fail Safe"

Diagnosis Work Sheet is useful to verify the incident.

Verify relation between the symptom and the condition when the symptom is detected.

>> GO TO 5.

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-1249, "Description"

and

EC-

699, "Fail Safe"

Diagnosis Work Sheet is useful to verify the incident.

Verify relation between the symptom and the condition when the symptom is detected.

>> GO TO 6.

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-704, "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.

>> Check according to

EC-706, "DTC Index"

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 the following.

With CONSULT: “How to Erase DTC and 1st Trip DTC” in

EC-667, "CONSULT Function"

>> 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.

Diagnostic Work Sheet

INFOID:0000000012198253

DESCRIPTION

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 a incident. It is

important to fully understand the symptoms or conditions for a cus-

tomer complaint.

Utilize a diagnostic worksheet like the one on the next page in order

to organize all the information for troubleshooting.

Some conditions may cause the MIL to come on steady or blink and

DTC to be detected. Examples:

• Vehicle ran out of fuel, which caused the engine to misfire.

• Fuel filler cap was left off or incorrectly screwed on, allowing fuel to

evaporate into the atmosphere.
