PROCEDURE
1. | CHECK CAN BUS WIRE (FORWARD RECOGNITION CAMERA MAIN WIRE) |
(a) Disconnect the cable from the negative (-) auxiliary battery terminal.
(b) Disconnect the T18 forward recognition camera connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
T18-6 (CANH) - T18-12 (CANL) | Cable disconnected from negative (-) auxiliary battery terminal | 108 to 132 Ω |
T18-6 (CANH) - I182-4 (CG) | Cable disconnected from negative (-) auxiliary battery terminal | 200 Ω or higher |
T18-12 (CANL) - I182-4 (CG) | Cable disconnected from negative (-) auxiliary battery terminal | 200 Ω or higher |
T18-6 (CANH) - I182-16 (BAT) | Cable disconnected from negative (-) auxiliary battery terminal | 6 kΩ or higher |
T18-12 (CANL) - I182-16 (BAT) | Cable disconnected from negative (-) auxiliary battery terminal | 6 kΩ or higher |
NG | GO TO STEP 5 |
