CHARGING CABLE CHECK




Visual check


1.Check the charging cable for the following items. If an abnormality is found, replace the charging cable.

  • Damage, corrosion or rust of cable, normal charging connector or plug
  • Excessive play or strain of normal charging connector or plug terminal
  • Packing deviation

Check on insulation resistance


caution When the insulation resistance is measured, set the range of the special tool electric insulation tester (MB992355) to 250 V. When the insulation resistance is measured at the range more than 250 V, the component may be damaged.


1.Use the special tool electric insulation tester (MB992355) to measure the insulation resistance at the plug side with the range of 250 V.
note The plug shape is different depending on the country. Perform the check according to the specification of each country, referring to the illustration.

Standard value:
Tester connection terminal
Standard value
1 - 2
1 MΩ or more
2 - 3
1 MΩ or more

2.Use the special tool electric insulation tester (MB992355) to measure the insulation resistance at the normal charging connector side with the range of 250 V.

Standard value:
Tester connection terminal
Standard value
1 - 5
1 MΩ or more
2 - 5
1 MΩ or more
3.If the resistance deviates from the standard value, replace the regular charging cable.

Check on normal charging connector built-in switch



1.Measure the resistance between the normal charging connector terminal No. 4 and the terminal No. 5.

standard value:
Normal charging connector release button
Normal condition
Without pressing release button
135 - 165 Ω (at 20°C)
With pressing release button
432 - 528 Ω (at 20°C)
2.If the resistance deviates from the standard value, replace the charging cable.

Check pilot signal terminal



1.Connect the charging cable with a home socket.
2.Use the analogue voltmeter from the normal charging connector side to connect the pilot signal terminal between the terminal No. 3 and the terminal No. 5. Measure the output voltage.
Standard value: approximately 12 VDC
3.If the voltage deviates from the standard value, replace the charging cable.
