what is the operating system
 

on a 96 camry le i have an obd2 tester and tried plugging it bin but it won't fit, so is it obd1 ,1.5 or 2.:confused:

96 is ODB2.

What plug are you using? Look under dash near steering column.

i looked under the dash by the steering colum and found a plug in but it had a round plastic piece around it.

There are two plugs, round and the ODBII.

Federal law requires the ODBII plug on this year of car.

i will look closer.
