NOT TO PUT ANYONE DOWN... Normally we use Flagship one for our computers, and for the last two times we had to get a GM computer, and BOTH times they messed us up by the instructions they sent us. We were trying for at least 3 hours to get it to work (2003 Chevy Impala), contacted them, NO HELP AT ALL! The person on chat kept insisting we had something wrong with the car, even though the old computer started the car fine (was not sending signal to turn fans on). We came across this video, and BAM, car started up on the first attempt. They had us just turning the key to the "ON" position, where you have us turning it to the "START" position. Just wanted to let you know that we will be doing a video about your company, and from now on, you have our business, THANK YOU!

[@acr]

Hello and thank you for the comment. Sorry to hear of the troubles with another company and glad we were able to help you get the vehicle running. There are a couple different procedures when it comes to a key relearn on GM vehicles and we have both videos posted here with the specifics. We are glad to have your business and look forward to working with you.

[@carlosvangrinder3754]

Thanks for posting this, it is probably helping a lot of people. Thought i would add my experience to the comments though as it didn't work for me. Apparently if the TDM is configured for export the 30 minute process will not work for you. If the car is made in the USA and exported then it doesn't work and you will have to program it with a scan tool.

[@acr]

Carlos, thank you for your input. This may be true for certain models but is not a blanket statement for all GMs that are exported. It would depend on the calibration and service#s and we prefer to address them on a case by case basis. If you would like to share your vehicle year/make/model It could offer some insight to those with that same vehicle.

[@carlosvangrinder3754]

@@acr True enough, best just to try it out and see if it works, if it doesn't you will have to have a scan tool to take care of the problem like i did. Thanks for creating this content.

@@acr i have an 06 GTO pontiac, would i need a scan tool for this procedure? I also heard i need 2 security codes for my car in order to do the relearn process. Do you have any insight on that ?

[@Mr-th5hw]

These gto’s were imported from Australia as a holden manaro

[@acr]

@@Mr-th5hw If you purchased the ECU from us, then you will not need a scan tool to relearn the key. These instructions apply to modules calibrated by us, but it may work in other scenarios. We also offer a service that will eliminate the security system, thus avoiding the key relearn altogether. The ECU must still be VIN programmed and calibrated to your specific vehicle. GM Computers carry a service # that applies to many models however, although the service# matches, the calibration is different. Please be sure that your replacement computer was properly configured for you.

Can u do this procedure with a Vin starting with 2 canadian made vehicle....my key broke got new key cut at gm trying to program it tried for 5 days now can't get it to work...do u need to disconnect the battery cable for 30 min to reset it before u try another 30 min cycle to reprogram new key

[@RetrieverTrainingAlone]

Important to turn key all the way to crank or start, and not simply to On position. I tried for 3 10-minute cycles but failed because I was not turning the ignition key all the way to the crank or start position instead of the On position.

[@acr]

Yes, there are 2 types of procedures depending on the vehicle model and year.

[@sinegra30]

Thank you! Does this only works with brand new blank PCM's? Is it the same process if I want to install a junkyard PCM?

[@acr]

The units that we provide are not blank. We supply ECMs that are correctly matched using the calibration required based on the VIN decode. Junkyard PCMs share similar service #'s but the calibration varies between models. In theory, it is possible but given that junkyards will not accept returns on electronics, it could be risky. You would still need someone to program the VIN in the module as well.

Hi 🙋‍♀️ I have a 2006 Chevy Equinox and just bought a new computer for it. I went through the 30 minute process twice before the security light went out. There’s a misfire on the number 5 cylinder and I’m hoping that this new computer fixes the issue. My car has all new wires, plugs, the works installed so fingers crossed that this will help. The service engine soon light is still on after installing this computer though 🤔 My husband said the new computer would fix that issue but I’m not so sure about it until the codes are checked again. Any ideas on what I can do to fix this? I appreciate any information that you can give and thanks so much in advance. Love your channel by the way and a big thumbs up 👍 😎

I would suggest connecting a scan tool and check the actual codes and go from there. If you didn't buy the computer from us, the module may be missing the VIN and correct calibration and could trigger the CEL and possibly drivability issues. Keep us posted.

[@acr]

Hey Jordan, Heres what we have on that code for your vehicle: Disconnect the battery, Check the BCM Connector and be sure its fastened securely. If that doesn't work: 1. Watch traction control switch input in Body Control Module (BCM) data or with a Digital Volt Ohm Meter (DVOM) on the Brown/White wire, circuit #1571. Voltage should remain high, near 5 V or 12 V while switch is in the ENABLE position. Refer to the latest version of GM bulletin PIC5074. 2. If the switch status does not remain ENABLE, disconnect switch, road test. 3. If the status is now steady in the ENABLE position, replace the traction control switch. 4. If the status still changes with switch disconnected, check the Brown/White wire back to the BCM, pin 33 for a potential short to ground. 5. If the wire checks OK, verify the Brake Pedal Position (BPP) sensor voltage is 0.73 - 1.47 volts with the brake pedal released. 6. If OK, perform the BPP Sensor Calibration per GM document #2037786. Hope that helps!

What if the secerityi light comes on soon as you try to crank it and then goes off 2 seconds later?

[@acr]

It would be easier to answer that by diagnosing the vehicle and having a brief history of the issues you've been having. If you purchased an ECM from us, a tech support team is available to assist you, which you will find on the QR code we sent with the module.

[@alejandromedeles8833]

What about a relearn for Gm vehicles with push start , having my ecm reprogrammed and wondering if its same procedure

[@acr]

Same process, just press the engine start button instead of turning the key.

[@firefighter3989]

I have a 2004 silverado 2500 (not HD) 6.0 gas 4x4. It was running then shut off, I have the correct fuel pressure. It will crank but not start. replaced the crank sensor and cam sensor. No pulse to injectors, no spark from coils and no power to the crank sensor. PCM connectors had oil in them. I cleaned plugs and pcm with contact cleaner. Security light does not stay on. Key is very loose and can be removed at any position. Would this be a pcm, ignition or key problem?

[@acr]

Would be tough to say. The sec light won't remain on since it's not in a relearn mode and that has yet to be triggered nor does it appear that it would need to. This video is referring to performing a key relearn for individuals that are replacing the PCM. If I had to choose from the 3, I would lean towards the PCM but I recommend performing an order of diagnosis pertinent to your symptoms.

Hi, The anti-theft symbol appeared in the dash after i parked my 2015 Enclave in the driveway & the vehicle wouldn't start after that. The fobs no longer work either. Now when i attempt to turn the ignition ON , all systems, symbols & lights react slowly as though the vehicle is waking from a dead sleep. Are these common symptoms that may require a relearn or a deeper issue ?

[@acr]

Hi Judy, it would be really tough to say. I would recommend having the battery and battery terminals inspected first.

[@rolandovento7411]

I have a 2008 chevy silverado 1500, i bought a new pcm already programmed and tried this procedure, i did it twice but my truck wont start i there something else that could be affecting this? Just found out when i install the new pcm that the crankshaft sensor needs to be relearned

[@acr]

If you purchased a brand new PCM from the dealer it is not programmed and calibrated as they are unable to do such off-board procedures.

[@khaled001985]

Hello, my car is a 2022 rav4 hybrid. The smart computer ecu was stolen from it. What are the appropriate steps to solve the problem and operate the car? For information, smart key fob its available

[@acr]

We do not currently offer the PCM for that vehicle

[@tabithamanning3893]

I have a 2015 Chevy Cruze and it’s push to start. Can I do this procedure the same way ?

[@acr]

Follow the same procedure but instead of turning the key, just press the start button with the key fob in the correct area.

[@user-jt3jg633]

Why is flagships programing the keys so much different?

[@acr]

We are unsure about other companies' calibration and programming processes. We are licensed by automakers and utilize their software for programming.

[@gideonarmoohjnr5911]

2014 Chevrolet Cruze no crank no start But the anti-theft light goes off when the ignition is on. After diagnosing I get the B3055

[@acr]

Did you purchase the Computer from us?

[@albertozagami7127]

Hello, I got a Captiva 2.4 Sport 2011. Unfortunately I had already installed the tool and run a check before watching your video. What problem could this have caused? I have run the first 10 minutes cycle but the code light did not turn off. What could possibly be the underline cause? What should I do? Thanks

[@acr]

Was the computer purchased from us?

[@stanrosenfield1116]

The PK3+ 30 min procedure worked. The vehicle turns on with new key; however, the anti-theft icon won't go away. If I turn on the vehicle with the original key, the new key doesn't work. What to do?

[@acr]

Was the computer purchased from us?

[@ajose223w3]

So if I bought a brand new one without a vin on it I can’t do this?

[@genek3961]

Which procedure should be used for the 2012 Chevy Cruze with the flip out key because didn't see that key in your pictures of keys?

[@acr]

Hello Gene, The 2012 Chevy Cruze is equipped with PK3+. This is the correct video to follow if you had purchased a unit from us that is programmed and calibrated to your vehicle.

[@genek3961]

@@acr Ok thanks and I didn't purchase my ECU from you but the immobilizer light should be illuminated when the new ECU is installed right because the one that I purchased "supposed to be plug and play" but it started car 1 time and now car just keeps turning over and won't crank but security light came off and on like usually when starting car.

[@angelleal9936]

Nice video tech sr! So... Basically for a ECM programming we only have to change de VIN and make a Key's relearn? Greetings!

[@acr]

calibration is critical

[@drynalove8184]

In order for this to work do you need to depress the brake before turning the key in the ignition starting position?

[@acr]

No, You only need to press the brake pedal if you have a push button to start vehicle.

[@happyday8422]

Good video. Ty..

[@justinray381]

Just installed one of your units in my 2011 Avalanche and the key learning process is not working. Truck will start with the old PCM but will not run very long before it throws P0691 codes.

[@acr]

Have you been able to troubleshoot those codes?

[@robertmercer6656]

Should my battery light flash? I recently had my truck put in the shop and put my truck in security mode. I got a new pcm, and i’m about to relearn but my battery light and fuel light comes on

[@acr]

This is pretty common as you are leaving the key on the 'ON' position which illuminates some of the cluster lights. Be sure the battery is fully charged and/or connected to a tender. If the battery dies while performing this procedure it could corrupt the software on the PCM

[@cj599]

i had a 2014 sonic replacement ecu and after about a month one day it would not start no security light i did the 30 min procedure and no start no crank we even tried to pull start it its a manual and nothing no ignition no fuel etc only code i received was a p0315 code have you ever seen that i believe the ecu i received might have failed i also did the crank relearn when i installed that ecu from flasgship one just curious if you have seen that before

[@acr]

We are uncertain how other companies program and calibrate their units. Are they offering any type of assistance?

[@throughlifeon2wheels850]

They actually made me retract my review on google before refunding me i ordered one from you guys and to be honest the turn around has been a long wait not impressed so far sorry to say craig pfeiffer is my order name

sorry my phone was logged into my other account

[@haldchilds850]

I have two keys to my 2004 Cadillac SRX 3.6L I just ordered my ECM today from you guys, do I have to do this program procedure for both keys?

[@acr]

You would only need to perform this procedure with 1 key. If both of the keys you had previously ran the vehicle and both are chipped keys, then any one of them will work.

[@haldchilds850]

@@acr Thank you sir

[@trinirider9688]

I have a 2011 GMC Acadia installed a new ECU and did everything in your video the car fired right up i took it fir a drive and everything works the problem is when i parked and came back 10 mins after it went straight back into anti theft mode i relearn they key twice and the same thing keeps happening any ideas whats causing it to forget the relearn process

[@acr]

Difficult to say without properly diagnosing the vehicle but I would lean towards the actual anti-theft system (not the ECU) having an issue.

[@chrismcallister2083]

does a 2015 chevy equinox have pk3+/passlock?

[@acr]

2015 Equinox uses the PK3+ system

[@Rayl3w]

Trying to do this with my 2011 camaro but the security light doesn't turn off after 10 minutes. I sent them my Vin as well & they told me it was a passkey 3. I put on the stock module & the car start but it's misfiring.

[@JavonteThePlug]

did you ever figure this out Im having the same issue where "service theft deterrent system" after 10 minutes stays up

[@RunescapeIsDrew]

I have a 2005 Pontiac Grand Prix Gxp , I installed a used ecu from another car , my theft info comes up , reason why I installed is because the original ecu hit the starter and shorted out and that caused my car not to start , with the use I just installed I had a lock smith come out and did a key for it and nothing happed , what should I do ?

[@acr]

Mr. Dixon, My first suggestion would be to inspect the vehicle for electrical shortages. The ECU would be incapable of shorting the starter as it is a low voltage part. The starter, however, if not grounded and/or has malfunctioned is capable of damaging electronics. Secondly, if the ECU has malfunctioned, you can easily purchase one from us at www.allcomputerresources.com which is pre-calibrated and VIN programmed specifically to your vehicle, once you receive that ECU from us, you would follow this relearn procedure and will not require a locksmith or mechanic.

[@popamarin4941]

does this procedure also work when I use an identical computer taken from another car? Can it be adapted to my car without the need for a software connection?

[@acr]

The short answer is No. The PCM will require specific calibration to your vehicle along with the VIN which has the PIN codes to carry out the key relearn.
