2009 sterling with a isb 240 cummins one..normal operating..FAULTY

Resolved Question:

I have a 2009 sterling with a ISB 240 Cummins one of the codes tells me that (engine turbo 1 speed data valid but below normal operating range-moderately severe level) second code tells me (ECM CRITICAL INTERNAL FAILURE-FAULTY INTELLIGENT COMPONENT OR DEVICE). With these codes I was wondering what could be the problem changed sensor on the turbo stayed the same. When I have my computer connected and I press more info it wants to shut down.

Hello , my name is Joe

From what you describe - Cummins fault 111; It seems like you have a bad ECM.

This fault code is triggered when the internal ECM diagnostics detect a read or write error internal to the module.

This fault code can only be caused by an internal ECM problem. Repairs are not possible for the ECM.
