Here is background to this release. Advances in technology have increased the availability of SMOG check simulators or, as they are often called, “defeat devices” in California. There is a black market of simulators developed specifically to assist individuals thwart the California Smog Check Inspection process. Here, millions of dollars are at stake. However, the problem can occur when unscrupulous used car dealers or individuals in the used car market buy cars that will not pass SMOG and then use the SMOG check defeat devices to pass them off as vehicles which have successfully passed the SMOG check process. The station owner and/or technician who smogged the car may not, in actuality, be to blame as they are being defrauded by the dishonest used car dealer, purchases, or even end consumer.

The fact that the Bureau of Automotive Repair is aggressively accusing station owners and/or technicians can results in thousands of dollars of unnecessary legal costs up to and including the loss of their SMOG certification or license. The letter recommends that every shop, every technician, every individual who is in school or thinking of ever performing a SMOG check inspection to immediately buy a scanner capable of transmitting live data. They should then plug in and hit the throttle to see live data to make sure the RPM’s fluctuate.
