When Using The Voltmeter

Use the special tool to connect a voltmeter between the ground terminal and the ETACS terminal of the data link connector. If the voltmeter indicator deflects once when each switch is operated (ON/OFF), the ETACS-ECU input signal for that switch circuit system is normal. See Fig 1 .
