Hey all, OSS here;

Was wondering if our trucks have a built in code reader, similar to my old 97 Cadillac STS(r.i.p), where you could hold two buttons on the HVAC, and codes would be displayed. I know there isn't an LCD screen for that in our trucks, but perhaps an old style OBD1 flash type? Just got a CEL on lastnight after I ran out of fuel that day, so I'd like to trace it asap, I don't have a code reader, and in Canada, I can't borrow one from Napa or anything, thanks!

On an OBD II equipped vehicle, nothing I can think of unless you have OnStar and an active account. Maybe someone else has a trick I'm not aware of.

 

PLX Kiwi - Kiwi Wifi, Kiwi Bluetooth, Kiwi MPG, Kiwi Drive Green OBD 2 Devices Try this I am looking at buying one. I know it is not built in, and OnStar won't work on anything under 2005...they didn't make the upgrade kit for Blazers and Jimmys

 

hah thats cool

 

As stated, most GM 96+ vehicles do not have any way of displaying OBD2 codes besides some Cadillac models.

If you wanted to go with a pod mounted gauge that can also read the trouble codes, I have used the Aeroforce Interceptor gauge before. Had one in my Bonneville, but sold it after I sold the car.

 

quick fix go to autozone they read the codes for you free of charge and give you a printout. good way to keep the parts biz goin
