POWER TRUNK LID SYSTEM Power Trunk Lid does not Operate

DESCRIPTION

The main body ECU (driver side junction block) continuously monitors the luggage door opening cancel switch. When the luggage door opening cancel switch is OFF, a luggage door opening switch signal is sent to the luggage closer motor assembly from the main body ECU (driver side junction block) via CAN communication. This actuates the power trunk opener operation, which opens the luggage door. When the luggage compartment door closer switch is ON, the luggage closer motor actuates the power trunk closer operation. When the key is held or all doors are unlocked and the electrical key transmitter sub-assembly is not held, and the luggage electrical key switch is ON or the key's luggage compartment door opener switch is pressed, the luggage closer motor assembly actuates the power trunk lid opener operation.
