Turn on the switches so that the specified voltage (current) is supplied to the location to be measured. Judge if the circuit is normal by evaluating whether the measured voltage (current) matches the specification.

• Voltage between terminal #1 and body (two- or three-polarities): Disconnect the connector with the key switch in the OFF position. Measure voltage between terminal #1 (5-V power source) of the body harness end connector and the body (ground).
• Key Switch: ON Position
• Black (negative) terminal on tester: To the body (to ground)
• Red (positive) terminal on tester: Terminal #1
Measured voltage is specified voltage: Section up to #1 terminal is normal if 5±0.5 V
Voltage between terminal #3 and body (three-polarities): Disconnect the connector with the key switch in the OFF position. Measure voltage between terminal #3 (5-V power source) of the body harness end connector and the body (ground).
• Key Switch: ON Position
• Black (negative) terminal on tester: To the body (to ground)
• Red (positive) terminal on tester: Terminal #3
Measured voltage is specified voltage: Section up to #3 terminal is normal if 5±0.5 V.
Voltage between terminal #1 and grounding terminal (two- or three-polarities): Set the key switch to the OFF position and disconnect the connector. Measure voltage between terminal #1 (5-V power source) on the body harness end connector and the ground terminal (terminal #2 for two-polarity or terminal #3 for three-polarity connector).
• Key Switch: ON Position
• Black (negative) probe terminal of circuit tester: To ground terminal (Terminal #2 or #3)
• Red (positive) probe terminal of circuit tester: Terminal #1
If the measuring voltage is within 5 ± 0.5 volts, the circuit up to terminal #1 and the ground terminal (terminal #2 or #3) is normal.
Voltage between terminal #3 and grounding terminal (three-polarities): Set the key switch to the OFF position and disconnect the connector. Measure voltage between terminal #3 (5-V power source) on the body harness end connector and the ground terminal (terminal #1).
• Key Switch: ON Position
• Black (negative) probe terminal of circuit tester: To ground terminal (Terminal #1)
• Red (positive) probe terminal of circuit tester: Terminal #3
The circuit up to ground terminal (Terminal #1) is normal.
