POWER MIRROR CONTROL SYSTEM(w/ Memory) Reverse Shift-linked Function of Power Mirrors does not Operate

DESCRIPTION

On receiving a reverse signal from the park/neutral position switch assembly, the power management control ECU 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. Each outer mirror control ECU then performs control in response to the reverse signal.

   CHECK MEMORY AND REACTIVATION FUNCTION

   
   
   1. 

      Turn the power switch on (IG).

   2. Using the outer mirror switch assembly, turn the mirror surface to the fully left position.

   3. Press the M1 switch while the SET switch is being pressed.

   4. Check that the buzzer sounds for 0.5 seconds and the mirror surface position is memorized.

   5. Using the outer mirror switch assembly, turn the mirror surface to the fully right position.

   6. Press the M1 switch.

   7. Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the recorded fully left position.

      Result
      Result Proceed to Memory and reactivation functions are normal. A Memory function is not normal. B Reactivation function is not normal. C
