Hi all,
I need some help on my car listed above it is a Sedan. I have ABS light, brake/parking light and engine light on my dashboard. Also, no temperature indicator. Gas gauge works fine. I have tried connecting two different OBD2 scanner. But It just say cannot established the link to DLC. I have checked all fuses under dash and under the hood. All are fine. Also checked power ON OBD 2 connector between PIn 4 and Pin 16. It shows twelve volts. How can I find the code for my car? I have tried shorting pin 4 and 9 as well but no codes coming. (FYI: I have after market Compustart Car starter installed. Is it the problem?)

Thanks.
