Checking the hydraulic switch (Scorpio 2)

The hydraulic switch must be checked if the indicator on the instrument panel does not light or lights up continuously. If the indicator lights up continuously, the oil pressure must be checked first. If the oil pressure is OK, the following checks must be performed.



Turn off the engine and disconnect the "arrow" plug connector of the hydraulic switch (the ONS engine is shown in the figure).

Start the engine and close the plug contact to ground (for example, to the crankcase).

If the indicator lights up, the hydraulic switch must be replaced. If the indicator does not light up, then either the indicator lamp is defective or the electrical wire is broken; check the electrical circuit using the electrical wiring diagram.

Connect the hydraulic switch plug connector.
