Input Signal Inspection Points
DIAGNOSTIC FUNCTIONINPUT SIGNAL INSPECTION POINTS
When Using the Scan Tool
1. Connect the scan tool to the data link connector.
CAUTION: The ignition switch should always be turned OFF when connecting and disconnecting the scan tool.
2. If buzzer of the scan tool sounds once when a switch is operated (ON/OFF), the ETACS-ECU input signal for that switch circuit system is normal.
When Using the Voltmeter
1. Use the special tool to connect a voltmeter between the ground terminal and the ETACS terminal of data link connector.
2. If the voltmeter indicator deflects once when a switch is operated (ON/OFF), the ECU input signal for that switch circuit system is normal.
