< BASIC INSPECTION >

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 (Print them out with CONSULT-III.)

-

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 

XX-XX, "*****"

 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 

XX-XX, "*****"

.

6.

 PERFORM BASIC INSPECTION

Perform 

DEF-3, "Work Flow"

.

Inspection End>>GO TO 7

7.

 DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE

Detect malfunctioning system according to 

DEF-6, "System Description"

 based on the confirmed symptom in

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

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

System Diagram

INFOID:0000000001697541

System Description

INFOID:0000000001697542

Operation Description

• Turn rear window defogger switch ON when the ignition switch is turned ON. Then controller (auto amp.)

(rear window defogger switch) transmits rear window defogger switch signal to BCM.

• BCM turns rear window defogger relay ON when rear window defogger switch signal is received.
• Rear window defogger and door mirror defogger (with door mirror defogger) are supplied with power and

operate when rear window defogger relay turns ON.

• BCM transmits rear window defogger control signal to IPDM E/R via CAN communication when rear window

defogger operates.

• Rear window defogger ON is displayed when controller (auto amp.) receives signals.

Timer function

• BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch

is turned ON while ignition switch is ON. It makes rear window defogger and door mirror defogger (with door
mirror defogger) operate.

• Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns

rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch
is turned OFF.
