Launch Creader Elite Scan Tool

[revrnd]

@mrjulian416 I bought 1

 

after seeing your post elsewhere about being able to lower the TPMS 'low pressure setting'. Under the Chevrolet 'tab', the TPMS is listed

but there doesnt appear to be an explanation how to access it to change the setting or any other TPMS functions.

 

Also can anyone explain this:

 

I know some RPO codes came up on the screens as you go thru.

 

TIA

The target tire pressure setting is accessed through the body control module options.  Without connecting and walking through it myself, I can't recall the exact the menu selections needed, but it was not buried too deep in there, and once into the BCM, the choices were pretty intuitive.  Next time I get a chance, I'll try to remember to hook up and document the steps.

 

You'll find a screen where you can enter an expected pressure in kPa for both front and rear tires.  Just to be clear, units matter.  Don't enter a value there assuming psi or you'll effectively remove the low pressure warning (50psi = 345kPa, if you enter '50' you've set the low pressure warning to be ~7psi).

 

No idea about the chassis module version...

I played around a bit after supper. I was able to find the TPMS sensors and system selections for the '4 corners'. I wasn't able to see how to reset anything.

 

The manual does mention a Job List:

but I don't see a way to access it on the scan tool.

 

This is the home screen of my Creader Elite:

 

Online I did find online a video of a Creader Elite (BMW version) & this is the home screen of it:

I'm not sure if the 'Reset button' is to reset the tool or the vehicle.

I posed a question about not being able to set the tire pressure warning on Amazon. I got a reply to send an email. I did explaining what I wanted to do. This is the reply I got:

 

Checking Amazon, Launch does offer a CANFD adapter, but apparently not for the Launch scan tool. I will email to see what is up. As it stands, I've got something that I wouldn't have ordered had I known its limitations.

[revrnd]

I asked about the CAN FD adapter's compatibility w/ the Elite G scan tool. Apparently it is fine.  So I'll order that & go from there.

 

There mention of CAN FD going thru the screens but I'm not sure in what context (I think it was a yes/no question).

I'll connect tonight and try to get pics of the steps involved in what I did.

To recap, I bought the "GM specific" reader in the link I posted above.  Before I connected it to the truck, I powered it on with the USB cable, connected to wifi and did the initial software update and downloaded the GM specific software that was included with the purchase.

 

Connect it to the OBDII port.  I then turned the ignition on, truck off (mine is an SLT with push button start.  Push and hold the start button without pressing the brake pedal until things 'turn on').  Then to get to the tire pressure warning adjustment:

 

1. Diagnostics

 

2. GM

 

3. Ok

 

4. Automatically search, and 5. Yes

 

6. If not already 'on', follow the Ignition on, engine off instruction.  Otherwise hit OK.

 

7. Common functions

 

8. The reader will begin to scan the various modules of the truck.  You'll get a series of questions about what modules are installed.  If you get it wrong you won't break anything.  You are not writing any info at this point. If I didn't know the right answer I just picked the first option.  Here is what I used: 0301, MYD, 0501, SRW, not equipped, U1D, UHS, not equipped, IOT, 0627, AUN, UD5, 

 

10. Scroll down to select tire type reset

11. Select tire type/pressure selection

 

12. You'll then get two screens with a short story about passenger car tires and light trick tires.  Just hit ok twice

 

13. Touch the current tire pressure target number (413 in my case). It will ask you to enter a new value in kPa for the front. Touch the blank spot for the 'Expect Value' to enter the new value.  Follow the prompts to save/write the new value.  Just a heads up, if you enter the same value as what is currently showing, you will get an "out of range error".

 

14. Continue to update the rear.  Follow the prompts to save/write the new value.

 

Make any/all changes at your own risk.  You are responsible for your actions and any changes made using the reader.  This story was based on my experience only.  Your experience may vary. etc etc etc.

@mrjulian416 Thanks very much. I'll save those pics to a folder & see how things go.

I've created my own printed doc from your reply.

 

I see your truck is a 2021 model. From what I got as an answer to my question on Amazon, 2022 & up models need a CAN FD adapter. I know I did get a question about CAN FD when I plugged in & worked my way thru the screens. That being said, I was able to see the tire pressures.

See but not change?

From where I got to, yes. I will run thru your procedure later this morning & post what I find.

Going thru the screens, everything is the same up to Step 6. When I select OK, this screen appears:

 

I guess that confirms the emails saying I need the CAN FD adapter.

 

I have ordered one. Amazon says 1 to 2 month delivery unfortunately, plus we have a postal strike here.

 

When it arrives, I'll see how it goes. Thanks for the assistance.

Not sure if they can get it to you any faster, but Launch has it "in stock" on their website

 

Launch CANFD adapter

My adapter came in the mail today, so I'll see if I have a chance to reset the threshold.

Everything went well until Step # 7 & then I got to this:

 

 

No reference to TPMS elsewhere.
