DESCRIPTION
The hybrid vehicle control ECU assembly 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 front multiplex network door ECU. Based on the signal, each front multiplex network door ECU then performs control.

CAUTION / NOTICE / HINT
Note
The power mirror control system uses the CAN communication system and LIN communication system. First, confirm that there is no malfunction in the CAN communication system and LIN 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.
Tech Tips
The reverse shift-linked function will not activate when both the mirror select switch L and R switch are off.
