With Voltmeter

When using a voltmeter
1. Use the special tool to connect a voltmeter between the ground terminal and the diagnostic output terminal of data link connector.
2. In the same way as when using the scan tool, turn the ignition switch to ON and turn on the auto-cruise control main switch. Then take a reading of the diagnostic trouble codes from the movement of the needle on the voltmeter.
