POWER WINDOWS


INSPECTION PROCEDURE D-1: Power windows do not work at all. <except vehicles for Argentina>
	CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.

	COMMENTS ON TROUBLE SYMPTOM If the power windows do not work at all, the power window relay, the power window main switch or the ETACS-ECU may be defective.
