S80 2.9 L6-2.9L VIN 94 B6294S (2000)
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.
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.
Check pins and terminals particularly for this fault.
Short-circuit to ground, permanent faults
A short-circuit between a live cable and ground is often indicated by the loss of a function or a fuse blowing when a current is passed through the
cable.
To repair wiring and cable terminals
Checks:
-
Activate all switches and sensors in the circuit. Check whether the fuse blows
-
Disconnect the connectors in the circuit to ensure that they do not affect readings.
Use an ohmmeter to take a resistance reading between the cable and ground.
The ohmmeter should read infinite resistance if no components are connected.
Check pins and terminals particularly for this fault.
