The main body ECU and the combination meter are connected with a cable and the CAN communication line. DTC B2282 is stored when signals, transmitted through the cable and communication line, do not match.
This DTC is stored when a malfunction occurs in the IG1D output circuit, which is between the IG1 No. 3 relay actuation circuit inside the main body ECU and the IG1 No. 3 relay.
