Lexus RX (RX 350L, RX450h) 2016-2025 Repair Manual: Check Bus 4 Line for Short to +B
DESCRIPTION
There may be a short circuit between one of the CAN bus lines and +B when there is no resistance between terminal 22 (CA2H) of the network gateway ECU and terminal 16 (BAT) of the DLC3, or terminal 7 (CA2L) of the network gateway ECU and terminal 16 (BAT) of the DLC3.
| Symptom | Trouble Area |
|---|---|
| There is no resistance between terminal 22 (CA2H) of the network gateway ECU and terminal 16 (BAT) of the DLC3, or terminal 7 (CA2L) of the network gateway ECU and terminal 16 (BAT) of the DLC3. |

WIRING DIAGRAM
CAUTION / NOTICE / HINT
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
NOTICE:
- Before measuring the resistance of the CAN bus, turn the engine switch off and leave the vehicle for 1 minute or more without operating the key or any switches, or opening or closing the doors. After that, disconnect the cable from the negative (-) battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.
-
After turning the engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.

Because the order of diagnosis is important to allow correct diagnosis, make sure to begin troubleshooting using How to Proceed with Troubleshooting when CAN communication system related DTCs are output.

-
After performing repairs, perform the DTC check procedure and confirm that the DTCs are not output again.
DTC check procedure: Turn the engine switch on (IG) and wait for 1 minute or more. Then operate the suspected malfunctioning system and drive the vehicle at 60 km/h (37 mph) or more for 5 minutes or more.
-
After the repair, perform the CAN bus check and check that all the ECUs and sensors connected to the CAN communication system are displayed.

HINT:
- Operating the engine switch, any other switches or a door triggers related ECU and sensor communication on the CAN. This communication will cause the resistance value to change.
- Even after DTCs are cleared, if a DTC is stored again after driving the vehicle for a while, the malfunction may be occurring due to vibration of the vehicle. In such a case, wiggling the ECUs or wire harness while performing the inspection below may help determine the cause of the malfunction.
