5 - Mirror Facing Direction Is Not Memorized

CIRCUIT DESCRIPTION

While the driver's and passenger's door ECU monitor the mirrors facing direction via the mirror facing direction detection sensor, the both door ECU receive a memory signal multiply from the seat ECU and the theft deterrent ECU transmits ACC signal multiply to the driver's and passenger's door ECUs as well. This time the mirrors facing direction is memorized by the seat ECU, being transmitted multiply to the seat ECU.

NOTE: Power mirror control system has a function with a large-scale body multiplex communication. First of all, inspect the communication function according to "how to proceed with troubleshooting", and check that no malfunction exists in the communication system. Then proceed with the troubleshooting.
