DESCRIPTION
There may be a short circuit between the CAN bus lines when the resistance between terminals 6 (CANH) and 14 (CANL) of the DLC3 is below 54 Ω.
| Symptom | Trouble Area |
|---|---|
| The resistance between terminals 6 (CANH) and 14 (CANL) of the DLC3 is below 54 Ω. |

*: w/ Navigation System
WIRING DIAGRAM
INSPECTION PROCEDURE
Tech Tips
Operating the engine switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
PROCEDURE
DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and the branch wire.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
Note
After turning the engine switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work Click here.
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
