Open-Circuit, Permanent Faults

Open-circuit, permanent faults







An open-circuit in a cable is indicated by a loss of one or more functions.
Chafed and broken cables or terminals that have come loose are common causes of faults in electrical systems.


Checks:
- Disconnect the connectors at both ends of the cable.

Connect an ohmmeter between the ends of the cable.
The ohmmeter should read approximately 0 [ohm] if there is no open-circuit in the cable







Always check the control module and control module box connectors to ensure that their pins and sockets are not bent or damaged, as this can cause faults.
