a. For an open circuit in the wire harness in Fig. 1, perform a resistance check (step b) or a voltage check (step c).
b. Check the resistance.
1. Disconnect connectors "A" and "C" and measure the resistance between them.
Resistance: 1 Ohm or less
HINT: Measure the resistance while lightly shaking the wire harness vertically and horizontally.
Fig. 2:
Between terminal 1 of connector A and terminal 1 of connector C -> 10 kOhm or higher
Between terminal 2 of connector A and terminal 2 of connector C -> Below 1 Ohm
In this case, an open circuit exists between terminal 1 of connector "A" and terminal 1 of connector "C".
2. Disconnect connector B and measure the resistance between the connectors.
Fig. 3:
Between terminal 1 of connector A and terminal 1 of connector B1 -> Below 1 Ohm
Between terminal 1 of connector "B2" and terminal 1 of connector "C" -> 10 kOhm or higher
In this case, an open circuit exists between terminal 1 of connector "B2" and terminal 1 of connector "C".
c. Check the voltage.
