Without Scan Tool

WHEN USING A VOLTMETER





1. Connect an analog voltmeter to the diagnostic output terminal (No. 6 terminal) and the ground terminal (No. 4 or 5 terminal) of the data link connector 1.

CAUTION: Be sure to use the special tool (diagnostic trouble code check harness) to connect the voltmeter to the ground terminal (No. 4 or 5 terminal).

2. Obtain the diagnostic output by observing the voltmeter pointer deflection.
3. Repair the problem location, referring to the diagnostic chart.

WHEN USING THE CHECK ENGINE/MALFUNCTION INDICATOR LAMP





NOTE: Other diagnostic trouble codes also output as the same code numbers as when using the scan tool.
