Voltage and Signal Check
1) Check voltage using voltmeter (1) connected to each terminal of couplers.
2) Check signal using oscilloscope (2) connected to each terminal of couplers.
NOTE
• As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when
ignition switch is turned ON.
• Pulse signal cannot be measured by voltmeter. It can be measured by oscilloscope.
• Item with asterisk (*) in normal voltage column can be read only by oscilloscope.
