Goodness, score on z55 struts.

BTdieselwork makes a product that allows adjustments to the TPMS settings. The module pops into the OBD reader. Along with displaying / removing any DTC through the console it gives about 10+ other updates.

I have already adjusted my TPMS pressure settings using my scanner. They were set at 45psi. I set them down to 32PSI as 45psi is just too stiff for my liking.
I will however increase tire pressure when towing or notice abnormal tire ware. I generally run 35psi front and 32psi rear On Suburban type vehicles.
Running these pressures i have never seen uneven tire ware across the tire contact patch.

The BTdieselworks thing seems WAY overpriced to me for what it does. 50 bucks maybe but not $300

huh. I've never tried adjusting tpms. what scanner do you have?

I'm guessing you're adjusting at what psi the warnings go off?

I have a Snap On Solus pro. Bought it used from a retiring mechanic near me for $300. Lots of keys and he said recent software. I never checked as it just works for what i need.
I do not know how high up in years it will work on but it does do everything i have needed on my 2014 Avalanche.

Yes, i used it to adjust at what psi the light comes on.

My suspension is Z55. After doing a bunch of reading and research i can not figure out what the sub code's really mean. 6JL and 7JL.
I know they mean left and right but is there anymore meaning then that?
The reason i ask is the struts i bought are listed to fit my Z55 Denali at GM parts giant but does not include the code 6JL or 7JL, so im confused.

interacting. I'll have to look on my tech 2. wonder of snap on had an option the clone tech 2s.dont.

 

[SpareParts]

I don't know. Never used a Tech 2 or clone but i would sure think it also has it being a GM made tool.
