CHARGING CABLE CHECK
Required Special Tools:
 
 
 
 
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, charge connector or plug
  • Excessive play or strain of charge connector or plug terminal
 
 
Check on continuity
1. Check the continuity between the plug ground terminal and the normal charging cable ground terminal.

Terminal No. 3Terminal No. 5Continuity exists
2. 5 If there is no continuity, replace the normal charging cable.
 
 
 
Check on insulation resistance
cautionWhen the insulation resistance is measured, set the range of the special tool electric insulation tester (MB992355) to 250 volts. When the insulation resistance is measured at the range more than 250 volts, 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 volts.
 
Standard value:
Tester connection terminalStandard value
1 – 31 MΩ or more
2 – 31 MΩ or more
2. Use the special tool electric insulation tester (MB992355) to measure the insulation resistance at the normal charging cable connector side with the range of 250 volts.
 
Standard value:
Tester connection terminalStandard value
1 – 51 MΩ or more
2 – 51 MΩ or more
3. If the resistance deviates from the standard value, replace the normal charging cable.
 
 
 
Check normal charge connector built-in switch
1. Check that the unolck button works normally.
2. Measure the resistance between the normal charge connector terminal No. 4 and the terminal No. 5.
 
Standard value:
Normal charge connector unlock buttonNormal condition
Without pressing unlock button135 to 165 Ω [at 20°C (68°F)]
With pressing unlock button432 to 528 Ω [at 20°C (68°F)]
3. If the resistance deviates from the standard value, replace the normal charging cable.
 
 
 
Check pilot signal terminal
1. Connect the normal charging cable with a home socket.
2. Use the analogue voltmeter from the normal charge 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 V
3. If the voltage deviates from the standard value, replace the normal charging cable.
