Chevy & GMC Vans

Since all years of vans have the potential to set codes, here are some sites with helpful information to explain & diagnose them.

Has anyone seen a list of GM enhanced OBD-II parameter ID's, specific to the Safari/Astro?
How about a list of trouble codes?
I just got a Scanguage2 as a gift, and would like to have a list handy.

Yeah, I have a little booklet that I made with all the codes I could find on the net. Anyone that wants it just shoot me an email and I'll send it to you.

Maybe a mod could make it available for download from the site.

I found out the DTC's are actually listed in my Hanes manual, and you can get the PID's from the scanguage website.

You should be able to look up any code on the website thread listed here...

Great links, v8famvan!

I tried adding the engine torque data to my guage but that didn't work, but tranmission fluid temparature did. I thought Astros didn't have that sensor because I've read of other people installing them. It will come in handy when I'm climbing those steep rough mountain roads or going through snow. Anybody know what the normal range of temperatures is?

Above 200 degrees F and you better be taking it easy. If you have full synthetic fluid, above 230 and you gotta let off.

Sorry I've been lame. The ODB-II book is available to download from here.
