Im stuck!!!! I go to flash a tune on a 2005 Cavalier and when I click write i get a fail that says Controller Unlocker/ Timed out.
No wifi so I cant post anything. Any help? 4192034443
Literally a 100miles from home and car now wont start.
Were you doing a write calibration or a write entire?
What software version are you using?
Make sure you're waiting at least 15 sec after key on before you try the write. Also, post the last tune you wrote to the vehicle.
Make sure that no lock/Master_Slave data is included in this window. Press clear if it is ... EDIT>Calibration Details>Remote Tuner

I have tried a write caliberation, and full write. I am running version 3.0.37
I posted the tune. Here is the Suit info
*removed*
I am not sure how to post a screen shot but I followed your instructions Motown and there was nothing in the remote tuner box to clear or Slave data
full write can brick your PCM. You should only do a full write if you are changing the operating system, an operating system parameter, or are recovering from a full write.
Your tune does not appear locked in any way. It's possible you bricked it by trying the write entire, then pulling the fuse.
So had the car towed back 100miles. Got it in the shop, disconnected the battery and letting it charge, also unplugged the PCM for the time being. Not sure either will make a difference but I seen some posts that said it might. I have a aftermarket radio and about the same time I put it in I upgraded to 3.0 software. Before I never had any issues writing caliberations into the car. After I notice it was hit or miss with bootloader time out error messages. Some time I could flash a tune, sometime it wouldn't unless I waited for some time. I never could get it the issue to reproduce so I took it as being software. Now I see people say the aftermarket radios with door chime adapter causes issues. So I pulled the radio fuse. Went for a flash and I also select slow speed or unchecked high speed down load. Seemed like it worked, took about 6 minutes or so. Then car would not start. Scanner will not connect or read the pcm. I am getting the message...... Controller Unlocker, Timed out. This is waiting longer then 15 seconds to flash. That brings me up to when I posted on here....while sitting long the road.
That's funny but not funny because had the HPtuners shops they always full write.... no maybe they meant with what they tune and that not being my car model. Is there anything else Bill to try, trouble shoot, experiment before I go hunting to a pcm?
I dont follow your timeline. Did that stuff happen before you towed, or after you towed.
"That brings me up to when I posted on here....while sitting long the road." - this makes your post confusing.
These were not my shops. I got off work "Firefighter" and drove to a local store and had about 20 min of logging from the drive. At the store I made a few VE table changes and went flash. Pulled the radio fuse to see if I would avoid the bootloader time out errors I had been having from time to time. No luck so I tried a couple more tries and had no luck on high or slow speed more. The car would not start. So I was stuck along the road well parking lot. So I uninstalled HPTuners and reinstalled, I tried restarting computer, I tried flashing as soon as I tuned the key on as well as letting it wait some time. I some how got it to flash using the slow speed. It took about 6-7 minutes and said it completed. After that I still could not start the car as well as I was getting the error, Controller Unlocker, time out. I have tried differnet USB ports on laptop. With the cable disconnected from laptop I have a green light on the interface. I didn't have loose battery connections or blow fuses to my knowledge. So after all that I was on the good ol google and searching shops that were open that tune GM with HPTuners. This is the same time I post on here with my cell. I since, had the car towed and I am not home, car is in shop with battery and pcm disconnected and battery on charger. I don't think voltage was a issue as it was a new battery.
According to that, the car didn't even start writing before you had no start issues, so, it's likely related to something else.
Yes the car ran to where I stopped. It wrote in low speed and appeared to be a slow but good flash. However it would just crank and not fire. I then was unable to get the scanner to connect and read as well as when I would try to flash even the stock tune I get the Controller Unlocker timed out as soon as I click "Write"
if you failed during a write entire, you must perform a write entire to recover it.
If you failed during a write calibration, you should recover it ONLY using write calibration. Trying to recover a write calibration with write entire can make matters worse.
Im going to go back out. Reconnect the PCM, Reconnect the battery, remove radio fuse and try a write calibration
and see what happen
You said you did a "full write" during the process, so you'll have to do a full write to recover it.
ok, I will try full write
Im trying to do a relearn on the secutity system. I don't hear the fuel pump prime and I am getting a Error on the cluster where the odometer would be.
fuel pump doesn't prime because the pcm is corrupt. You have to recover it with a write entire, because you wrote entire and failed during your recover efforts. As a result, you may have bricked the pcm.
So I reconnected the PCM, then re connected the battery and left on trickle charge. I followed GM's procedure for the security system relearn. Car still would only crank over but not start. I pulled the radio fuse and tried to connect the scanner. I attached the screen shot. Its not seeing the PCM. I tried to read the PCM via Editor and got a "detect protocol failed" message. I tried to flash a tune via "Write Entire" high and low speed and got the message "Controller unlocker/ Time out". I also tried this with by flashing "write calibration only" and got the same message. I then tried all the above with the radio fuse in... and had the same results. So last I tried to connect my handheld scanner tool and it would not connect to the car. It is saying class II data link malfunction. I am guessing I bricked the pcm unless you might have any other suggestions to ideas. If I have to replace, can I just get a junk yard pcm of similar year, engine, trans and features like power locks and windows? I know the vin will be off but is it plug and play? I would then have to buy a new license Id assume?
I saved the screen shots to word and I will be danged if I can get them to upload. Its been uphill all day.
See if this shows up
How did you get on popeye??
I had this exact same thing happen tonight. I made a quick load and it completed 100% and now the truck wont start. I get the same exact error, Controller unlocker - Timeout. I was using write calibration just like I have done the last 30 times in the last week. Was there ever any resolution to this?
Unless you preformed a scan, then tried to "Write Entire" without first clicking disconnect or closing the scanner, then pulled your radio fuse immediately after clicking "Flash", you may not have done the exact same thing and may need to start a new thread with more detail to get the best resolution or maybe even ultimately contact support.
You're right, I did not do the exact same thing. But I did end up with the same error. I was attempting to get the OP to post if he found any solution. I am working with support to try and figure out what happened. Thanks
Add another one to this list here as well. Looks like I'm getting the same error. Minor VE changes to a 411, and all of sudden I go to write calibration and get the Unlocker Timed Out error. Looking to see if OP figured it out, or if this is starting to look like a bug in the 3.0 versions. I did not attempt a write full, no fuses were pulled etc. Performing the same VE updates i've done hundreds of times.
You can add another to the list. Was trying to write to my 06 Silverado... Last week 8/8/16 had no problem... Then on 8/11/16 "Wham".. Tuner time out left me on side of road. Had it towed...ECM replaced with reman... and on 8/12.... "Wham"...AGAIN...!!!
Tried everything up above (except pulling stereo fuse)... No avail.... Now I am waiting for another REMAN ECM....!!! This has to be an HP Tuner Software issue... Seems to be all too common an occurrence..
Update... Removed Radio fuse... Tried to write again in High Speed Mode.... WORKED!!!!!! Truck started right up....YoooHoooo!!!!:p:) :) :worship: Now just have to cancel New ECM order....!!!
Nice!
Yeah... It must have something to do with after market stereos that use a separate interface to keep the stock steering wheel stereo controls and chime alarms like door open, key in ignition, etc.... It might somehow be interfering with the data transfer. Don't know if this an exclusive problem to GM or if it is an across the board thing for Ford and Dodge as well. Doubt HPT will be able to rectify the problem through software programming an debugging, considering the sheer amount of after market stereo and vehicle combinations out there.. Best bet is just to pull the fuse before doing any data updates.. When HPT tells you there is a STEEP learning curve...They aren't kidding....
Just to add a tiny bit to this, I also have an aftermarket stereo head in my TA, plus one of those adapters so that it all works with the wheel controls etc., but I have never had a issue. So presumably it varies by stereo/os/year blah... :( HPT wouldn't be working THAT one out in a hurry...!
-D
It does seem like there is a correlation between the two. Like you said D.. Probably a combination of factors, including interface specs, OS, make, model and year...Etc... Some have issues, others don't...
It's strictly related to the radio.
Some aftermarket radios do not obey commands to stop communications when they're supposed to. There is no fix other than to buy a radio that shuts up when it's told to do so, lol, or, just pull it's fuse during programming.
So then, I'm curious... If the problem is the stereo, and the unit has a detachable face, would removing the face have the same effect as pulling the fuse?:shrug:
