Input Signal Inspection Points

When using the scan tool (MUT-II)
1. Connect the scan tool to the data link connector 1.


CAUTION: Turn off the ignition switch beforehand whenever the scan tool is connected or disconnected.


2. If the scan tool makes a peep sound when each switch is operated (turned ON/OFF), the input signal to ECU is normally sent from the switch circuit system.




When using the voltmeter
1. Connect a voltmeter to the ETACS terminal and the ground terminal of the data link connector 1 using the special tool.
2. If the voltmeter pointer deflects once when each switch is operated (turned ON/OFF), the input signal to ECU is normally sent from the switch circuit system.
