MICU Control Functions Index
SystemFunction
22-82Multiplex Integrated Control System
System Description (cont’d)
The MICU (built into the under-dash fuse/relay box) is one of the B-CAN components. The MICU controls many
systems related to the body controller area and security system, and also works as a gateway to the diagnose the
other B-CAN connected ECUs with the HDS.
Refer to the each system circuit diagram in detail.
Multiplex Control Sends the switch input signal information to the MICU and outputs the information. The MICU controls the ECUs electric load and communication based upon the information
received the B-CAN.
On-Board Diagnosis The MICU has a gateway function which sends the results of the MICU internal diagnosis and the B-CAN connected ECUs diagnosis to the HDS.
Self-Diagnosis Test mode 1 diagnoses the communication line between the MICU and B-CAN connected unit. Test mode 2 checks the switch inputs connected to the MICU.
Interior Light(s) The MICU controls the interior lights ON, OFF and dimming based upon the information of the related switches and/or the B-CAN related information.
Sleep Function The MICU has a sleep function, which it enters during the power down mode.
The MICU also controls the function of these circuits:  Entry lights control (map lights and ceiling light)
 Exterior lights control (including the daytime running lights control)
Horn
 Interlock system
 Key-in reminder
 Keyless entry
 Lights-on reminder
 Power door locks
 Power window key-off timer
 Seat belt reminder
 Security alarm
 Turn signal/hazard flasher
 Wiper/washer
