Hi all I flashed all my modules successfully through esys but the IHKA module came up with completed with warning. I have since noticed my DL side won’t blow hot air now. I have tried reflashing and no success the software parts were successful now I’m at a loss and the module shows up with no errors in ista.


[IHKA - 78] possible timing violation detected during execution of service TD - TransferData [WARN]

Check in svt IHKA has missing files

How do I do that?

 

[GAM388]

How do I do that?

And if so how do I fix it?

 

[GAM388]

Get svt by using Read ECU. check if IHKA list has any fff or UNKN or if cafd is missing.
If its missing calculate svt soll then flash again.

Didn’t work, couldn’t see any ffc unknown. And won’t appear in the sw update list

 

[GAM388]

If you read ecu can you see IHKA module or not?

Not in the update screen but it appears in the read ecu SVT list down the side like the others. Error comes back in Ista, but clear faults and test it comes back clear, even done all the troubleshoot and test plan processes:-(

 

[GAM388]

That is ok must be in red just write this svt_soll back to vcm

I think everything was blue or black nothing was red

 

[GAM388]

Read ecu and post picture of ihka module in svt three

Here is the svt actual read ecu and the fully calculated one

Esys is 3.30.1version

 

[GAM388]

Right click on IHKA and button CODE. Everything is ok with IHKA on picture. After you code IHKA go with ISTA and clean error. If you see that AC button flashing wait 1 min til ihka initialisiert

Can you explain how it relates to the flashing issue and resolves it, just so I understand. Was I meant to do the Code button for each of the ecus once they were flashed?

Looks like some but no luck on this one, no errors showing in Ista or bimmerlink (where they showed before) Heat is minimal and blower is lower than passenger side even when on full. Yet ac aspects work fine. Passage will crank the heat and blow strong but not drivers, do I try and get psdz .39 full and do another reflash of all

 

[GAM388]

Have you checked the blower motors?
You can try to reflash the IHKA module

Checked the blowers and reflashed, same finished with errors message

 

[GAM388]

WIth errors?

The completed with errors Esys message, but no fault errors

 

[GAM388]

It’s the same as I posted before. Could it be the valves or something, still blowing cold and not strong fan speed but is fine on air con cold
