DESCRIPTION
The ECM sends the reverse signal to the main body ECU (multiplex network body ECU) via CAN communication. When receiving the reverse signal, the main body ECU (multiplex network body ECU) sends the reverse request signal to each outer mirror control ECU assembly. Based on the signal, each outer mirror control ECU assembly then performs control.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
Note
The power mirror control system (w/o Memory) uses the CAN communication system. First, confirm that there is no malfunction in the CAN communication system. Refer to the How to Proceed with Troubleshooting procedure.
Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.
