WIRING DIAGRAM
CAUTION / NOTICE / HINT
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
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 P5 forward recognition camera connector.
(c) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | P5-5 (CA1P) - P5-11 (CA1N) | Cable disconnected from negative (-) auxiliary battery terminal | 54 to 69 Ω | | | *a | Front view of wire harness connector (to Forward Recognition Camera) | | |
NG | | REPAIR OR REPLACE CAN BRANCH LINES OR CONNECTOR (FORWARD RECOGNITION CAMERA) |
OK | | |
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 | P5-10 (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.
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
P5-7 (IGB) - Body ground | Power switch on (IG) | 11 to 14 V |
NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT) |
