Cummins ISX fault # 3697

[Rawze]

FAULT CODE 3697 -- Engine Control Module Calibration Memory - Bad Intelligent Device or Component


-- You have a ram memory vs. flash program mis-match. This is usually an indication of a corrupt program.

I.E.> Make an insite ecm image, then re-flash the ECU with a clean factory program that matches what the the ser# engine calls for on quickserv.

Restore and features and parameters/insite image to restore the settings for that make/model truck.

Crank it up and let the truck run for a good 10 minutes to re-build the ecu's internal ram data + re-establish cylinder balancing data, etc. before continuing on.

If the fault does not go away, maybe the ecm is going bad.
