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).

>> GO TO 2

2.

 CHECK DTC

1. Check DTC.

2. Perform the following procedure if DTC is displayed.

-

Record DTC and freeze frame data.

-

Erase DTC.

-

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

3. Check related service bulletins for information.
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-III 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-III 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-III to the vehicle, and check diagnostic results in real time.

If two or more DTCs are detected, refer to 

BCS-80, "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 in 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 Confirma-

tion Procedure.

Is DTC detected?

YES

>> GO TO 8

NO

>> Refer to 

BCS-81, "DTC Index"

.

6.

 PERFORM BASIC INSPECTION

Perform 

BCS-3, "Work Flow"

.

Inspection End>>GO TO 7

7.

 DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE

Detect malfunctioning system according to 

BCS-8, "System Description"

 based on the confirmed symptom in

step 4, and determine the trouble diagnosis order based on possible causes and symptom.

>> GO TO 8

 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 9

NO

>> Check voltage of related BCM terminals using CONSULT-III.

9.

 REPAIR OR REPLACE THE MALFUNCTIONING PART

1. Repair or replace the malfunctioning part.

2. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replace-

ment.

3. Check DTC. If DTC is displayed, erase it.

>> GO TO 10

10.

 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.
Does the symptom reappear?

YES (DTC is detected)>>GO TO 8

YES (Symptom remains)>>GO TO 6

NO

>> Inspection End.
