signal circuit(s) or the ETACS-ECU may be 
defective. Note that this function can be 
disabled/enabled by the adjustment function (default 
setting; enabled).

POSSIBLE CAUSES

•

Malfunction of the door switches

•

Malfunction of the room lamp

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors
