Open-Circuit, Permanent Faults

Open-circuit







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

Checks:
- Disconnect the connectors at both ends of the cable.
Check the cables visually, Checking Wiring and Terminals. Permanent Fault
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.






If the reading is not correct. Replace the cable and/or continue, according to "Contact Resistance and Oxidation". Contact Resistance and Oxidation

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.
Check pins and terminals particularly for this fault.
