Fault code: EMS 26117 SCANIA

Error identification:

The engine control unit does not register an engine speed signal.

Cause:

The fault can be due to the teeth on the starter motor and on the flywheel gear ring not meshing so that the engine is not turned.

The fault code also occurs if there is an electrical fault on the engine speed sensors or electrical cables meaning that the engine control unit does not receive an engine speed signal.

Notes:

The start attempt is terminated after a few seconds if the engine control unit does not receive an engine speed signal.

Action:

Delete the fault code and try starting again.

It may be necessary to turn the engine position a little.

To determine whether this is an electrical fault, check whether there are fault codes for the engine speed sensors.

Check the engine speed sensors and electrical cables.
