X15E3 CM2350 Cruise Control fault

[BAMtech]

Hi all,

We recently rerated one of our trucks from 600hp 1850ft LH10035.04 to 600hp 2050ft LH10082.00. All configuration in features and parameters has been verified the same as before the new calibration.

We have lost our cruise control function when driving, the idle up still works when stationary, clutch and brake switches are working, the ecu is seeing road speed and I can see the cruise control switches operating in data monitor.

Anyone have any suggestions or any more information on the workings of the cruise control system?

Thank's in advance.
