56 Ω Or Less: Wiring Diagram
CAN communication system. See appropriate SYSTEM WIRING DIAGRAM article.
NOTE:
When the bus line is measured, combined resistance of end resistance (120 Ω) in body integrated unit and end resistance (120 Ω) in keyless access CM can be measured. The combined resistance is approximately 57 - 63 Ω. When the measured resistance value is 56 Ω or less, main wiring harness or related lines may be shorted, or combined resistance may have changed because resistance other than end resistance is created on the circuit.
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK BETWEEN MAIN WIRING HARNESSES. Using the tester, measure the resistance between terminals. Connector & terminal (B280) No. 11 - No. 21: |
Is the resistance 10 Ω or less? | Go to step 2 . | Go to step 3 . |
| 2 CHECK MAIN WIRING HARNESS AND RELATED LINES. With a tester connected, disconnect control module connectors in order. Connector & terminal (B280) No. 11 - No. 21: |
Is there any control module whose condition has changed from short state? | Replace the control module whose resistance has changed. | Repair or replace the short circuit of the main wiring harness and related lines between body integrated unit and keyless access CM. |
3 CHECK CONTROL MODULE.
|
Is the resistance 115 - 135 Ω? | Go to step 4 . | Replace the control module whose end resistance value is out of the specified range. |
| 4 CHECK HARNESS. With a tester connected, disconnect control modules in order. Connector & terminal (B281) No. 11 - No. 21: |
Are there any control modules whose resistance changed to 1 MΩ or more? | Replace the control module that has changed. | Repair or replace the harness due to resistance component. |
