Pre-Collision not available

[hutangjun]

Hi everybody,

I have update CCM module firmware yesterday night sucessful with UCDS and got the warning message "Pre-Collision assist not available" on the instrument cluster.

with forSCAN got the DTC code: B1433 - Forward Looking Sensor Alignment
Missing Calibration

anybody know how to re-enable ACC function on my case? thanks in advance.

Here we use a different tool, not forscan

Sorry I‘m used UCDS tool to update CCM, and then only use forscan to read the DTC

This is DTC error in UCDS tools

[larsmdk]

you need to calibret the CCM, under spec. function, can be it is not possible, then in direct config, there is one where says "uncovergent" that one you can change to "convergent" then the ACC works again, but be carefull when testing, because can be it is not working correct.
UCDS is working on the calibrations function, is not sure it works good right now
