Cat 257B S/N SLK 02102 Auxillary Hydraulic Solenoid Value Coil part

[Nige]

Are you able to open the ECM and look for burned out components?

If it does come down to the ECM I would suggest to enquire about any Reman option first. If there is a Reman option and you open up the ECM you can kiss the Core Credit goodbye. It will not qualify by virtue of the fact that it has been opened.

There are also companies that repair ECMs.

The Aux Hyd Control ECM is Part Number 216-0658. There is a Reman available P/N 10R-5613 that is unprogrammed. It would have to be flashed by a dealer in order to work. So not plug & play.
