OBD2 not communicating
1996 LS 400. I just need to get my Lexus smogged. No indicator lights are on. Running good. Every place I go to their OBD2 cannot communicate. Fuses are good. My smog is already overdue. Please help.

OBD 2 not communicating
1996 LS 400: I just need to get my Lexus smogged. No indicator lights are on, fuses are good Running good. Just under 160,000 miles. Every place I go to, their OBD2 cannot communicate. Smog is already overdue but the registration is paid. 😇

In the last two years, I know of three people who could not get their OBD2 reader to scan, all three were worn out catalytic converters.

Thanks so much everyone for the info. Yes I have a technician I can consult. I had it in for a repair and he said it would read and I could get it smogged. Wrong. I'll share your ideas with him. I was just trying to avoid taking it to the dealer.

I can sympathize with you, MissIrvine.....nobody likes to pay for more vehicle repairs than the minimum absolutely needed. But like it or not, even as far back as 1996 (when, by Federal law, the first OBD II computers were installed in American-market new cars)...the days of DIY (do-it-yourself) underhood electronics were pretty much gone. The average car owner, short of a professionally or factory-trained technician, simply does not have the training or equipment needed to perform anything but the most rudimentary things underhood on modern vehicles.
