Tech Tips
w/o Dynamic Rear Steering System:
The network gateway ECU (sub bus monitor ECU) stores DTCs when it detects a communication stop or network communication error for ECUs connected to sub bus 2.
w/ Dynamic Rear Steering System:
The network gateway ECU (sub bus monitor ECU) stores DTCs when it detects a communication stop or network communication error for ECUs connected to sub bus 18 or 19.
The main body ECU (multiplex network body ECU) (sub bus monitor ECU) stores DTCs when it detects a communication stop or network communication error for ECUs connected to sub bus 1.
The driving support ECU assembly (sub bus monitor ECU) stores DTCs when it detects a communication stop or network communication error for ECUs connected to sub bus 13.
The certification ECU (smart key ECU assembly) (sub bus monitor ECU) stores DTCs when it detects a communication stop or network communication error for ECUs connected to sub bus 15.
