Read & programed THEN ** security access denied - invalid authorization code

[ProTools4]

Ok this is weird.

04 1500 Siverado

-Read the program saved & saved as new name
-Did the 1bar RTT OS upgrade then uploaded to the PCM

Now I'm locked out
cant read the PCM cant write to the PCM
Can see the vin and connect but not read or program

I keep getting...
"security access denied - invalid authorization code"

pulled all the PCM fuse, and checked the cigarette lighter fuse
unplugged all the cables usb and OBD and restared the laptop
unplugged the battery and touched the cables together
checked voltage at the cig lighter
called prior tuner 12secss and made sure he did not lock the PCM

Still nothing.
"security access denied - invalid authorization code"

How can I have read and programmed this PCM but be locked out?
Did I miss a fuse?

TAD

anyone

If you did NOT do a write entire with the RTT OS that would be the main problem.

[ProTools4]

It is very possible I made a mistake like that and did not wire entire.

I was in the middle of loading the file and I had three people hounding
me to show them the new nitrous purge at the same time.

Would that partially scramble the OS.
The the VCM will act as if it was locked?

It will not allow me to write entire or read now.

[EC_Tune]

That definitely doesn't sound good. Quick test: If you key on, does the fuel pump come on? If not PCM is SOL.

[ProTools4]

truck runs fine and datalogs too!

[EC_Tune]

Go back to the previous tune. Did you tuner lock it? If you did that's the problem.

[Bill@HPTuners]

Posting the file you wrote to the pcm would be a good start.

[ProTools4]

I'll post the tune first thing Tuesday morning

[ProTools4]

here is the tune As Delivered pre OS upgrade to RTT

[ProTools4]

this is the tune posr RTT OS upgrade

[ProTools4]

Bill,

if you could get back to me ASAP I need to get this thing back on the road.

[Bill@HPTuners]

RTT or any custom operating system doesn't appear to be applied to either of those files, are you sure those are the correct ones?

[Bill@HPTuners]

Also since there is a discrepancy I would need a vcm suite infolog while connected to the vehicle in question(please delete your serial number & app key before posting)

[ProTools4]

Bill thank you for all this help

The first tune is the NA stock OS tune AsDelivered from the customer.

The second tune was me saving pre OS chage Doh~!

Here is the tune for the OS change. *see attached

thank you again

[ProTools4]

As for an infolog the truck is now offsite.
I will not see it till next week.

[ProTools4]

Bill anything???

[ProTools4]

Bill

Here is the info log hope this helps you help me.

[Bill@HPTuners]

Try rereading with the newest public version, nothing stands out in the file or infolog to me, if you can't read it out with 2.22 I'll have our engineer look over the given info.

[ProTools4]
