Diagnostic Procedure

DTC B12BD:00 (360° VIEW MONITOR CONTROL MODULE) 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. (See CLEARING DTC [360°VIEW MONITOR CONTROL MODULE] .) Retrieve the 360°view monitor control module DTCs using the M-MDS. (See DTC INSPECTION [360°VIEW MONITOR CONTROL MODULE] .) 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 .)
1		No	Go to the next step.
2	INSPECT 360°VIEW MONITOR CONTROL MODULE CONNECTOR CONDITION Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) 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.
2		No	Repair or replace the connector, then go to Step 8.
3	INSPECT REAR MOUNT CAMERA CONNECTOR CONDITION Disconnect the rear mount camera 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.
3		No	Repair or replace the connector, then go to Step 8.
4	INSPECT REAR MOUNT CAMERA CIRCUIT FOR SHORT TO GROUND Verify that the rear mount camera and 360°view monitor control module connectors are disconnected. Inspect for continuity between the following terminals (wiring harness-side) and body ground: Rear mount camera terminal A 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 W-Rear mount camera terminal A 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.
4		No	Go to the next step.
5	INSPECT REAR MOUNT CAMERA CIRCUIT FOR SHORT TO POWER SUPPLY Verify that the rear mount camera and 360°view monitor control module connectors are disconnected. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Switch the ignition ON (engine off or on). Measure the voltage at the following terminals (wiring harness-side): Rear mount camera terminal A Is the voltage 0 V?	Yes	Go to the next step.
5		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 W-Rear mount camera terminal A 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 REAR MOUNT CAMERA CIRCUIT FOR OPEN CIRCUIT Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Verify that the rear mount camera 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 W-Rear mount camera terminal A Is there continuity?	Yes	Go to the next step.
6		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 W-Rear mount camera terminal A 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 REAR MOUNT CAMERA Inspect the rear mount camera. (See REAR MOUNT CAMERA INSPECTION .) Is the rear mount camera normal?	Yes	Go to the next step.
7		No	Replace the rear mount camera, then go to the next step. (See REAR MOUNT CAMERA REMOVAL/INSTALLATION .)
8	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Always reconnect all disconnected connectors. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Clear the DTC for the 360°view monitor control module using the M-MDS. (See CLEARING DTC [360°VIEW MONITOR CONTROL MODULE] .) Retrieve the 360°view monitor control module DTCs using the M-MDS. (See DTC INSPECTION [360°VIEW MONITOR CONTROL MODULE] .) Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the 360°view monitor control module. (See 360° VIEW MONITOR CONTROL MODULE REMOVAL/INSTALLATION .) Go to the next step.
8		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] .)
9		No	DTC troubleshooting completed.
