Yes
=>Go to Inspection for open circuit in stereo camera battery power supply circuit.
No
Repair the connections as necessary.
1) Disconnect the stereo camera harness connector (L17).
2) Connect a test lamp between the battery power supply circuit (pin 1 of L17) and the body ground. Does the test lamp illuminate?
Refer to "LHD Stereo Camera" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Stereo Camera" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to Inspection for open circuit in stereo camera ignition power supply circuit.
No
Repair the open circuit or high resistance in the battery power supply circuit between the STEREO CAMERA(+B) 5A fuse and the stereo camera (pin 1 of L17).
1) Connect a test lamp between the ignition power supply circuit (pin 9 of L17) and the body ground.
Refer to "LHD Stereo Camera" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Stereo Camera" in the ETM (wiring diagram). (Open using the ETM viewer.).
2) Turn ON the ignition switch. Does the test lamp illuminate?
Yes
=>Go to Inspection for open circuit in stereo camera ground circuit.
No
Repair the open circuit or high resistance in the ignition power supply circuit between the STEREO CAMERA(IG) 5A fuse and the stereo camera (pin 9 of L17).
1) Connect a test lamp between the battery power supply circuit (pin 1 of L17) and the ground circuit (pins 4 and 12 of L17). Does the test lamp illuminate?
Refer to "LHD Stereo Camera" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Stereo Camera" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to Chassis CAN communication circuit inspection.
No
Repair the open circuit or high resistance in the ground circuit between the stereo camera (pins 4 and 12 of L17) and the body ground.
1) Inspect the CAN Low circuit and CAN High circuit between the stereo camera (pins 7 and 8 of L17) and the central gateway control unit (pins 1 and 2 of B41) for the following. Is the result normal?
Refer to "LHD Controller Area Network (Central Gateway C/U)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Controller Area Network (Central Gateway C/U (4JJ3 with DPD))" in the ETM (wiring diagram). (Open using the ETM viewer.).
