There I think is TSB available. If you have access to SI can read it. If you no have let me know to try to get via your VIN

You was correct. Doing HPCM2 reprogram BY DPS using those SPS files from archieve folder was reseting DTC's

 

Now i can do Serial Gateway updating aswell. First A and then B

You really mean brake+start button ready ?

Not service mode (long press for start button ) ??

test car if ready go to service mode (long press for start button ) and reprogram k56 A after B vin must change

  • Author

Car was tested OK.
Then power off on and then to service mode.
Then with DPS reprogramming Serial A, no errors
Then after that tried to  Do Serial B got that {0x0047 NOt in mapping matrix error}
I havent done after that anything. Car still on service mode

Did you ask that did i choosed cars own vin by using [get controller info] dialog.(attachment) ?
This method was atleast work for serial A.

Could you attach your Serial A and Serial B DPS files?  I'd like to take a look at them.  You're failing at the OS upload so I may have some ideas.

I've just re-read your log and that's VERY interesting.....  it struggled and struggled to get the first calibration uploaded, it kept timing out but it did eventually make it.  

 

Step 08 - Struggles to send the OS calibration but eventually makes it after lots of logic retries

Step 09 - Fails to get a proper response so jumps to retrying, jumps to Step 13

  It receives this with a return RequestCorrectlyReceived-ResponsePending (expected)

Step 13 - Delay for 1 second jump to step 14

Step 14 - Increment the counter then jump back to step 02 and start again

Step 02 - Request security access again

Step 03 - Reports programming state

Step 04 - Compares, jumps to Step 07 (calibration to decide whether to skip uploading the OS or not)

Step 07 - Prepare to upload the OS calibration again, sends a 34 request

*** Fails this time as the unit responds with code 22 ConditionsNotCorrectOrRequestSequenceError

 

Are you sure this calibration is compatible with this unit? 

 

It is interesting to me though that it does eventually make it through uploading the first calibration (note in step 08, many invoke retry logic messages but it eventually does finish and goes to step 09 to try the next).   I'm leaning it's either not compatible (but not sure) or you have some communication issue going on.

 

The attached will show the logic order  The goto's will depend on whether a step was successful or not.

 

I'll see if I can find my extra unit here after and try it on mine.

There is some weird/missing data in GDS2 log too..
Communication issues are totally not out of the question here!

 

OP, is your MDI2 original?

Try updating MDI software and firmware if necessary (write "bosch mdi software" in any search engine, it will take you to the right place). Also, do not use wireless connection.

Or your GDS2 and deliverable packet is quite outdated (from 2020..) and have some issues reading/interpreting data from newer control units.
