Can Autel Maxisys Write Vin To Pcm?
I've already diagnosed and confirmed a faulty pcm on the car. my question is, my autel maxisys has an option to write the vin to a new pcm. I've never used this test on the autel, any insight would be appreciated. we program many Chevrolet and ford with pass thru pro or rap kit, but I normally steer clear of these year range Chryslers due to issues in the past. just looking for insight if anyone else has used the autel to replace a pcm? also wondering if there are any implications with security system when doing this.
I cant personally say if that exact scanner can but I know with the Chrysler stuff that you can "transfer" the SKIM key (security) code and the VIN.....that feature has always been in the WCM/SKIM module. I can only recommend looking in there to see if it gives you that option.
To the best of my knowledge you should be able to go into the WCM / SKIM and do the PCM replaced function with the autel. You will be prompted for a PIN code, Should be pretty easy. If you have a drew tech j box you should be able to write the vin through that and will automatically "learn" the secret key via the j2534 tool box. Note this is a CAN vehicle so the skim clear / reset functions in…
The Autel will rewrite the VIN. You'll be asked to input the secret, four-digit pin code in order to be authorized to rewrite the VIN
Yes you can, should be under powetrain, ECM (Engine Control Module), special function, Check PCM VIN, and then just type your vin, no pincode needed. Should be a Gpec (2 connector) first generation with that 2.4L eng.
I’ve done it a couple of times with an autel. It was very easy. You just need the vin, don’t remember being asked for any other information.
Hi Mike, Most of the time you can change VIN with Autel. When you do there will still be a code in the PCM about the Secret Key. (P0633) It will not usually turn on SES light or cause a problem. This era of Chrysler does not work well with Witech or DRBIII. The Autel does quite well. I am not sure if the SKIM will be a problem on this one where the keys are already learned into the WCM/SKIM…
Do you know if this can be done with a used pcm or does it have to be new pcm?
I would 100% prefer used to reman or new. You can marry to the vehicle without having to load the program. Reman from OEM has dummy calibration that has to be updated to proper calibration to work. Additionally, Chrysler and other rebuilders often send out PCMs that have defects.
I believe Michael Christopherson is correct. You will still need the PIN for SKIM. It will ask you for it during the "PCM Replaced" routine.
You either have to use an LSID and get from FCA or use a tool like AutoProPad, Autel im508 or Smart Pro. Dealers used to share SKIMs with shops. Not so much any more.
If the old pcm still communicates you don' t need a pin. And yes autel will do it 100%
I've given customer the option of a pre-programmed and used pcm that i'll write the vin to. i'll let u know how it goes it I run into any glitches. thanks for the help gents. you guys are great.
Good Evening Mike, I was actually doing a 2008 Dodge Avenger today with a new PCM and it would not write the VIN. It kept saying that the PCM did not support this function when I went into the the WCM to input the pin to write the VIN. I ended up having to use Witech. I submitted a data log to Autel on my Ultra and the shop's Maxisys Elite because neither would accomplish the task so just keep…
I'm guessing when you said new pcm it means straight from the dealer, if that isnthe case is completely different since a new pcm doesnt have a software installed. First you have to program pcm with the latest calibration. and the you have to do a pcm replacement in which you will have to have the pincode for that car to finish the task. With a used pcm calibration is already in the pcm. I hope…
If i remember correctly you used to be able to rewrite the vin using the cardaq toolbox 3 from Drew Technologies. Correct me if im wrong...
Edwin, The function in the Drew tools only works with Pre-CAN Chrysler vehicles. I hooked up to a 2007 Durango today and had to use the Auto Pro Pad to complete the task. The Drew box did not work for this Model.
