Sorry Lexus told me it did not... Gee a dealer not knowing what they are saying........:whistles:
it just doesnt hold codes with the car off, when your CEL comes on while you are driving the difference is that if your car is obd1 when you turn the car off you lose the code until you restart the vehicle and you have to wait until the CEL comes back on but with obd2 vehicles the computer retains te code information
