Diagnosis System

MULTIPLEX COMMUNICATION SYSTEM (BEAN)

The BEAN communication line is used to control the power window regulator master switch assembly (driver door ECU), the multiplex tilt & telescopic ECU (tilt and telescopic ECU), the multiplex network body ECU No. 2 (body No. 2 ECU), the windshield wiper ECU (wiper ECU), the theft warning ECU assembly (theft deterrent ECU), the position control ECU & wiring assembly (power seat ECU), the outer mirror control ECU assembly (mirror ECU), and the rain sensor, which are connected to the instrument panel junction block assembly (body ECU). If there is a short circuit (bus down) in the line, the communication to the system that has a short circuit (bus down) will be disabled and the DTC concerning the system will be output from the instrument panel junction block assembly (body ECU).
