INSPECTION PROCEDURE

PROCEDURE

1. CHECK CAN BUS WIRE (MAIN BUS LINE FOR DISCONNECTION, BUS LINES FOR SHORT CIRCUIT)




(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG-B -- CHECK CAN BUS WIRE (FOR SHORT CIRCUIT)
NG-A -- CHECK CAN BUS MAIN WIRE (FOR DISCONNECTION)
OK -- Continue to next step.

2. CHECK CAN BUS WIRE (FOR SHORT TO +B)




(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- CHECK CAN BUS WIRE (FOR SHORT TO +B)
OK -- Continue to next step.

3. CHECK CAN BUS WIRE (FOR SHORT TO GND)




(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- CHECK CAN BUS WIRE (FOR SHORT TO GND)
OK -- GO TO HOW TO PROCEED WITH TROUBLESHOOTING
