With 360°View Monitor System


Outline

System malfunction location

360°view monitor control module calibration data parameter error

Detection condition
•  The vehicle control module (VCM) detects that the 360°view monitor control module received error calibration data from the vehicle control module (VCM) for 10 s.

•  Perform the DTC inspection for the vehicle control module (VCM).
•  Is the same Pending DTC present?
Yes
Go to the next step.
No
Go to repair completion verification 2.
2
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).
•  Is a DTC related to an internal malfunction displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
Go to the next step.
3
INSPECT 360°VIEW MONITOR CONTROL MODULE FOR MALFUNCTION
•  Perform the DTC inspection for the 360°view monitor control module.
•  Is a DTC displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
Go to the next step.
4
INSPECT CAN CIRCUIT BETWEEN VEHICLE CONTROL MODULE (VCM) AND 360°VIEW MONITOR CONTROL MODULE FOR MALFUNCTION
•  Inspect the applicable circuit for a communication error.
•  Is the circuit normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
5
INSPECT 360°VIEW MONITOR CONTROL MODULE FOR MALFUNCTION DEPENDING ON REPEATABILITY
•  Install/connect the part removed/disconnected during the troubleshooting procedure.
•  Clear the DTC recorded in the memory.
•  Switch the ignition OFF and wait for 30 s or more.
•  Switch the ignition ON (engine off or on) and wait for 30 s or more.
•  Perform the DTC inspection for the vehicle control module (VCM).
•  Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, replace the 360°view monitor control module and perform the repair completion verification.
No
Perform the [ACTION FOR NON-REPEATABLE MALFUNCTIONS].
If DTC is displayed
•  Repeat the diagnosis from Step 1.
If DTC is not displayed
•  Go to repair completion verification 2.
Repair completion verification 1
VERIFY THAT VEHICLE IS REPAIRED
•  Install/connect the part removed/disconnected during the troubleshooting procedure.
•  Clear the DTC recorded in the memory.
•  Switch the ignition OFF and wait for 30 s or more.
•  Switch the ignition ON (engine off or on) and wait for 30 s or more.
•  Perform the DTC inspection for the vehicle control module (VCM).
•  Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, perform the diagnosis from Step 1.
•  If the malfunction recurs, replace the body control module (BCM), then go to the next step.
No
Go to the next step.
Repair completion verification 2
VERIFY IF OTHER DTC IS DISPLAYED
•  Perform the DTC inspection.
•  Are any other DTCs displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
