COMMUNICATION ERROR INDICATIONS
- If a fault occurs in the body integrated unit or LAN system (in any unit or the communication circuit), a communication error indication is given at the trip information display area on the combination meter.
- The indication differs by the type of fault, and related indicators such as the CHECK ENGINE light illuminate.
- If a communication error indication is given, one or more diagnostic trouble codes are stored in the body integrated unit. To read out diagnostic trouble codes, use a Subaru select monitor.
- If more than one diagnostic trouble code is stored, indication is given in the following order of priority: (1) High-speed CAN (2) Low-speed CAN (3) integrated unit (4) EGI (5) TCM (6) VDC
NOTE: The indication returns to the normal trip display when the trip reset switch is pushed.
CAUTION:
- Information registered in the body integrated unit must coincide with the vehicle's equipment and specifications for normal operation and diagnosis.
- If the body integrated unit is brand-new or put in factory mode, the key ring illumination blinks to indicate that equipment setting is not completed.
