Any suggestions on a good CAN BUS tool ?

What do you want it to do, and to what?

Can bus is how the modules communicate with each other , I want a interface to see data transmitting between modules , I think , data would be signals ,power signals , youtube videos can explain better ,

Technically, CAN is partially used on the C6. The C7 solely uses CAN.

Our C5s use J1850 VPW (aka Class 2) which is serial data.

If you want a good knock off GM Tech 2 I got one from CareUcar. It was model SP23-C, their best one. Works perfectly. The original Tech 2's were made in China and these are an absolute duplication. I paid about $480 for mine with all the cables, case, and TIS 2000 software (and associated Key).

They ship and it gets delivered in about 4 days from when you order. I know lots of members who have one from them.

autoenginuity is what I use, has 2 way communication with vehicle and I can use it on all my cars and truck.

That appears to be a typical scan tool designed to only address emissions codes and select other codes. Can it read the other 11 modules and not just the PCM? Can it perform diagnostics on the HVAC system? Perform an automated ABS bleed of the brake system?

bluevette2001

Yes on all modules not 100% sure on the bleed, have to check mine. It also allows you to command sensors on/off or % open.

Looks like it does bleed too:

Thanks, that seems to be a very comprehensive tool. I think they could you an improvement on their initial webpage to better explain what it can do.

Can it provide internal control circuit voltages like the Tech 2 to verify diagnostic parameters?

Just curious if you know if you can modify RPO settings with it. That would be impressive.

Last question. Can it reprogram the PCM settings like fuel trim, etc.?

Went again their site. Damn impressive in my opinion. I like the fact that with another disk you can use it on many different makes of cars.

bluevette2001

You don't need another disk, all manufacturers they cover are already in there, you get an ACTIVATION code for whatever you buy. I have the GM and Ford module, need to get the Chrysler one for my Challenger.

I also use an Actron handheld for quick checks like I/M monitor status if I'm in a hurry and don't want to drag the laptop out. It also is capable of some tests (like EVAP) and can record data to capture issues.

They are both great tools but I think only the Tech II can do rpo codes.

Dadaroo I went to careucar, and bought the jc23-c , just what I was hoping for , I like that it is self contained , my lap top comes unreliable for the pc based tools , ideally I wanted a tech 2 but thought the price was out of the ball park saw some on Auction sites . Thanks again DaDaRoo for the Insite and taking the time to Respond , as well as All you other fellas with the helpfull comments

If you need any help in learning how to use it let me know and we can discuss on the phone. You will need to set it up in the house first and use the provided power connection for that. You will need to put in some of the adapter cables just used for initial setup also. I will provide you instructions on this you can review while it is being shipped. Just PM me with your email.

One thing to remember is to plug it into the car first and turn it on before you turn the ignition key to ON. Allows for a proper sync with the car.

I have several links that will help also. I can provide them via email also, not at home now. Don't let me forget.

You will be impressed by the professional quality of the unit and cables. Nothing cheap and flimsy at all.

When you go to put the card into the device do this: Have the unit screen facing you. The card has one side with a grooved "U" slot in it that will be inserted with that slot to your right. The other side will not have such a slot. Don't want you to try and force it in backwards. Any questions on that please let me know.

Mr. Sam

I will post the info here in case someone else can make use of it. Don't forget to contact me directly if you need to discuss anything.

There is some issue going on with Dropbox. PM me with your email and I will send you the PDF.

This link to the Users Guide "should" work.

My thanks to Dadaroo also. His satisfaction spurred me to buy the same unit. I've done a diagnostic on the wife's C5 Vert, and enabled TPMS on my 03Z. This Tech2 is cool, and I know with 2 C5s in the household, I'll get lots of use from it over the coming years.

I plan to pass the Tech 2 on to whoever gets my car along with all the spare modules so it can have a long life into the future.
