Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - NETWORKING
CAN COMMUNICATION SYSTEM (for RHD) - TERMINALS OF ECU
- HINT:
- Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
| DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL |
Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the CAN main wire and CAN branch wire.
- CAUTION:
- For vehicles with an SRS system:
- Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
- NOTICE:
Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the ignition switch, any switches or doors. If doors need to be opened in order to check connectors, open the doors and leave them open.
After turning the Ignition 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 ().
When disconnecting the cable, some systems need to be initialized after the cable is reconnected ().
