POWER MIRROR CONTROL SYSTEM(w/ Memory) Power Mirror cannot be Adjusted with Power Mirror Switch

DESCRIPTION

The outer mirror switch assembly sends the mirror adjust switch signals to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) then sends the received mirror adjust switch signals to each outer mirror control ECU assembly via CAN communication. Based on this signal, each outer mirror control ECU assembly operates the vertical and horizontal mirror motors to adjust the mirror surface position.

Note


  • The power mirror control system (w/ Memory) uses the CAN communication system and LIN communication system. Inspect the communication functions by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication systems are functioning properly.

  • Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.

  • The vehicle battery supplies power to the main body ECU (multiplex network body ECU) via the door control battery. Therefore, before performing this troubleshooting procedure, make sure to perform an on-vehicle inspection to confirm that the main body ECU (multiplex network body ECU) power source circuit is normal.
