POWER MIRROR CONTROL SYSTEM > Front Passenger Side Power Mirror cannot be Adjusted with Power Mirror Switch

for Preparation Click here


SYSTEM DESCRIPTION

This circuit detects the conditions of the mirror control switch.
The integration control and panel assembly sends information about the operating condition of the mirror switch (switch input signals) through the BEAN line. Then the switch input signals are sent to the front multiplex network door ECU (passenger side). Mirror adjustment is controlled by the front multiplex network door ECU (passenger side).
