Toyota Camry (XV70): Remote Control System does not Operate
DESCRIPTION
The main body ECU (multiplex network body ECU) receives remote control signals from the driver door key cylinder or wireless transmitter. Then, the main body ECU (multiplex network body ECU) activates the power window motor and sends the remote control signals to the sliding roof ECU (sliding roof drive gear assembly) via LIN communication. The sliding roof ECU (sliding roof drive gear assembly) receives the signals and activates the sliding roof motor.
CAUTION / NOTICE / HINT
NOTICE:
- The sliding roof key-linked function and sliding roof wireless transmitter-linked function are operative when the power window customize settings "Door Key P/W Up", "Door Key P/W Down" and "P/W Down W/Transmit" are set to "ON" using the Techstream. (The default setting of each is "OFF".)
- If the sliding roof ECU (sliding roof drive gear assembly) is removed and reinstalled or replaced, the sliding roof ECU (sliding roof drive gear assembly) must be initialized.
