NOTICE:
If the stored bus information does not match the current sub bus configuration, DTCs may be stored and fail-safe functions may operate.
HINT:
It is not necessary to perform initialization of a gateway monitoring ECU (sub bus monitoring ECU) when using a sub bus monitoring ECU which was installed to another vehicle with the same sub bus configuration.
(h) Precautions for when a gateway function equipped ECU (sub bus monitor ECU) detects communication DTCs for ECUs not connected to the ECU
(1) Refer to precautions when replacing a gateway function equipped ECU (sub bus monitoring ECU) and initialize the connection information of the ECU.
(2) Clear the DTCs and check that no DTCs are output.
(i) Difference between genuine navigation receivers/radio and display receivers and optional navigation receivers/radio and display receivers
(1) Some optional navigation receivers/radio and display receivers are available as CAN compatible devices. Be aware that some optional navigation receivers/radio and display receivers do not have the same diagnostic features or characteristics of genuine navigation receivers/radio and display receivers.
