Using the Voltmeter

DIAGNOSTIC FUNCTION

INPUT SIGNAL INSPECTION POINTS [VEHICLES WITH ETACS-ECU]




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