code readers

I have a 1998 SL2 and was wondering if a OBDII code reader would work?
If not what code reader should I get.
Thanks in advance!

Your car has OBDII, I don't know about reader compatibilities. Here's a
site that might help:

Any OBD II code reader compatible with GM vehicles should work.

There are 3 different communications protocols used on OBD II vehicles:
J1850 VPW, which GM uses, J1850 PWM, which Ford uses, and ISO 9141, which
most other manufacturers use. So you need a scan tool that supports J1850
VPW.

Actually, there's another protocol, CAN, which is starting to be used now
(such as on the ION and VUE) and which is supposed to become an
industry-wide standard, and which is different from the above three.

 

I bought mine at WallMart for $20., it came with a code handbook. Saved me
money twice already.

part # 3123

The 3123 is a GM OBD-1 reader for 1995 and earlier cars. For 1996 and newer
you need an OBD-2 (OBDii) reader and they cost more.

 

Perhaps a place like Harbor Freight or JC Whitney carry those then.

 

I paid $50 at Harbor Freight for a generic code reader for OBDII. It
only reads active codes, not the stored ones.
