Fault number (is not very different) but description is different with other scan tool and say ,,00614 [1556] B200087 - Control module. Cruise Control module (Control module, software incompatible).

Previously Address 13: Auto Dist. Reg had:

After clearing the error, the error reappears. Seems to be because of ADR software update. Does anyone know what needs to be done? Maybe it is necessary to make a new adaptation in 5F?

@chr : Hi. I'm not sure that a fault involving a memory check-sum error can be fixed by "mak[ing] a new adaptation in 5 F".

In your context, check-sums are a sort of mathematical verification process that is performed on a data stream when software is being loaded to make sure that the Bits in the binary code don't get flipped accidentally during transfer from one device to another.

What usually happens with this facility is that the data being transferred has its own check-sum value, which is made-up from the pattern of ones-and-zeros from ALL the Bits in the software update. When the upgrade is completed, a second check-sum is calculated from the data-stream that has been received. The two check-sum values are then compared to test that the received data faithfully reflects the sent data. In your case - the 2 x check sums haven't agreed.

So, the existence of a check-sum error suggests (to me at least) a problem with the software upgrade process. Perhaps you should make your problem the problem of the agent who installed the update. My motto when I have paid someone for a service - a problem shared is a problem abrogated !! :)

CHKS error in Technisat unit is because of software (system files) corrupted
it happen after unlock, or activate function.
after "bad" hack, errors can back after coing or adaptation changes , or any changes from radio

Indeed, Technisat was updated from SW P0356T to P0363T.
Maybe is necessary to make another update?
