Diagnostic Procedure

Step

Inspection

Results

Action

1

INSPECT VEHICLE CONTROL MODULE (VCM) AND BODY CONTROL MODULE (BCM) FOR MALFUNCTION

•  Perform the DTC inspection for the vehicle control module (VCM) and the body control module (BCM).
(See DTC INSPECTION.)

•  Is a DTC related to an internal malfunction displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [VEHICLE CONTROL MODULE (E)].)

(See DTC TABLE [BODY CONTROL MODULE (BCM) (E)].)

No

Go to the next step.

2

INSPECT 360°VIEW MONITOR CONTROL MODULE FOR MALFUNCTION

•  Perform the DTC inspection for the 360°view monitor control module.
(See DTC INSPECTION.)

•  Is a DTC displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [360°VIEW MONITOR CONTROL MODULE (E)].)

No

Go to the next step.

3

VERIFY VEHICLE CONTROL MODULE (VCM) DTCs

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Perform the DTC inspection for the vehicle control module (VCM).
(See DTC INSPECTION.)

•  Are any DTCs other than DTC B14F7:86 displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [VEHICLE CONTROL MODULE (E)].)
