V40 L4-1.9L Turbo VIN 29 B4204T3 (2002)
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.
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. See Check terminals visually.
Short-circuit to supply voltage. Permanent faults
