Diagnostic Procedure

Step

Inspection

Action
1
VERIFY OTHER 360°VIEW MONITOR CONTROL MODULE DTCs
•  Clear the DTC for the 360°view monitor control module using the M-MDS.
•  Retrieve the 360°view monitor control module DTCs using the M-MDS.
•  Is DTC U3000:41 or U3000:49 displayed?
Yes
Replace the 360°view monitor control module, then go to Step 8.
(See 360°VIEW MONITOR CONTROL MODULE REMOVAL/INSTALLATION.)
No
Go to the next step.
2
INSPECT 360°VIEW MONITOR CONTROL MODULE CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the negative battery terminal.
•  Disconnect the 360°view monitor control module connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 8.
3
INSPECT SIDE CAMERA (RH) CONNECTOR CONDITION
•  Disconnect the side camera (RH) connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 8.
4
INSPECT SIDE CAMERA (RH) CIRCUIT FOR SHORT TO GROUND
•  Verify that the side camera (RH) and 360°view monitor control module connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
?  Side camera (RH) terminal F
•  Is there continuity?
Yes
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
•  360°view monitor control module terminal O—Side camera (RH) terminal F
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has a short to ground.
Go to Step 8.
No
Go to the next step.
5
INSPECT SIDE CAMERA (RH) CIRCUIT FOR SHORT TO POWER SUPPLY
•  Verify that the side camera (RH) and 360°view monitor control module connectors are disconnected.
•  Connect the negative battery terminal.
•  Switch the ignition ON (engine off or on).
•  Measure the voltage at the following terminals (wiring harness-side):
?  Side camera (RH) terminal F
•  Is the voltage 0 V?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
•  360°view monitor control module terminal O—Side camera (RH) terminal F
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has a short to power supply.
Go to Step 8.
6
INSPECT SIDE CAMERA (RH) CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition off.
•  Disconnect the negative battery terminal.
•  Verify that the side camera (RH) and 360°view monitor control module connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
?  360°view monitor control module terminal O—Side camera (RH) terminal F
•  Is there continuity?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
•  360°view monitor control module terminal O—Side camera (RH) terminal F
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has an open circuit.
Go to Step 8.
7
INSPECT SIDE CAMERA (RH)
•  Inspect the side camera (RH).
•  Is the side camera (RH) normal?
Yes
Go to the next step.
No
Replace the side camera (RH), then go to the next step.
(See SIDE CAMERA REMOVAL/INSTALLATION.)
8
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Always reconnect all disconnected connectors.
•  Connect the negative battery terminal.
•  Clear the DTC for the 360°view monitor control module using the M-MDS.
•  Retrieve the 360°view monitor control module DTCs using the M-MDS.
•  Is the same Pending DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the 360°view monitor control module.
Go to the next step.
No
Go to the next step.
9
VERIFY IF OTHER DTCs DISPLAYED
•  Are any other DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [360°VIEW MONITOR CONTROL MODULE].)
No
DTC troubleshooting completed.
