Before measuring the resistance of the CAN bus, turn the ignition switch off and leave the vehicle for 1 minute or more without operating the key or any switches, or opening or closing the doors. After that, disconnect the cable from the negative (-) auxiliary battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.
After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.

HINT:

Before disconnecting related connectors for inspection, push in on each connector body to check that the connector is not loose or disconnected.
When a connector is disconnected, check that the terminals and connector body are not cracked, deformed or corroded.

PROCEDURE

1.	CHECK FOR OPEN IN CAN BUS LINES (FORWARD RECOGNITION CAMERA BRANCH LINE)

(a) Disconnect the cable from the negative (-) auxiliary battery terminal.

(b) Disconnect the V10 forward recognition camera connector.

Standard Resistance:

Tester Connection	Condition	Specified Condition
V10-5 (CA1P) - V10-11 (CA1N)	Cable disconnected from negative (-) auxiliary battery terminal	54 to 69 Ω

*a	Front view of wire harness connector (to Forward Recognition Camera)

REPAIR OR REPLACE CAN BRANCH LINES OR CONNECTOR (FORWARD RECOGNITION CAMERA)

2.	CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
V10-10 (GND) - Body ground	Cable disconnected from negative (-) auxiliary battery terminal	Below 1 Ω

*a	Front view of wire harness connector (to Forward Recognition Camera)

(b) Reconnect the cable to the negative (-) auxiliary battery terminal.

Standard Voltage:

Tester Connection	Condition	Specified Condition
V10-7 (IGB) - Body ground	Ignition switch ON	11 to 14 V

REPLACE FORWARD RECOGNITION CAMERA

REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)
