COS3 bootblock error 12212156

[bigblock69]

A little background, its a 98 camaro with a 0411 swap. I just finished the swap and did a full flash with a 12212156 with the fuel segment swap. Started the car up and did the CASE relearn and checked for codes, everything looked good so proceeded to do a full flash of the 02020003 and i keep getting a bootblock error. I also tried COS5 and got the same error, but after the error a can go back and do a full flash of the 12212156 file and it works fine.
I also updated 7, 8, flash scan bootblock and firmware.

After doing full flash of 02020003 did you do cal flash from the 12212156 file...?

( the full flash you did of 02020003 writes an un-populated file into the PCM, i.e. all the tables/parameters are empty )


The steps are as follows:
- full flash 02020003,
- cal flash from 12212156,
- read COS file back from PCM,
- edit COS file to correct B3647 and OOR cells and save COS file,
- cal flash saved COS file.

After I flashed the 02020003 it would pop up with flash failed. Or is that normal untill I do a cal flash.

No, "flash failed" is an error...

can you post the log text that appears during flashing.

I notified Tech Support.

[bigblock69]

Ok thank you for taking time to help greatly appreciated.

[joecar]

Also, can you post the COS file that you were flashing.

After flashing a custom OS the PCM will be left in an "error state" (i.e. what we call dead-poll). That is because a custom OS file does not contain any calibrations and the PCM cannot operate correctly without any calibrations. After the initial custom OS full-flash, you need to perform a cal-flash from a file that contains a valid calibration. I.e. follow the steps Joe posted earlier.

I'm not sure why the error is being displayed to the end user, but it is expected and normal for that to occur "behind the scenes".

Ok, understood, these are expected/ok then.
