2009 ISX ECU Fault...

2009 ISX ECU Fault code. Chech engine light flashs twice then goes out. Comes back 20 minuets later. Happened 3 times.

Mechanic's Assistant: What's the make/model/year of your truck? Engine type?

2010 Peterbilt 386. 992,000 mi. Had inline over haul at 830,000.

Mechanic's Assistant: Are you fixing your truck yourself? What have you tried so far?

No. OTR in NY state from Colorado. Just a checked coolant, and oil. Temp good and oil pressure good. Idling in a rest stop.
