CAN COMMUNICATION SYSTEM (for LHD) DIAGNOSTIC TROUBLE CODE CHART

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 power management control ECU stores DTCs when it detects a communication stop or network communication error for ECUs connected to sub bus 15.
