Vehicles from 1996 to 2000 can pass California smog with up to two (any two) registers unset.I spoke to Glen who told me the following: In sheer frustration, on my way home, I had called the California Bureau of Consumer Affairs to talk to a BAR Technical Advisor, at 80. Back at the smog check station, the catalytic converter monitor was STILL 'NOT RDY'.On the way back up from Gilroy to San Jose, I repeated this procedure with as many variants as I could think of.Then I reset the 3-minute timer, and put the transmission in 4th gear, and then kept the tach at 2100 to 2300 RPM, with the air conditioning switch turned on.I put the stick in 3rd gear, and kept the tach at > 3000 RPM, without decelerating for 3 seconds, for the entire 3 minutes (heading south on the 101 towards Gilroy, to avoid traffic).I tried to put the transmission in 4th, but I couldn't get the tach and speed to agree with the chart above, so I opted to just follow the RPM and time requirements.I got on the highway, and set my cellphone timer to 3 minutes.

I left the smog check station, because they refused to run the test.I'll look at the TSB to see what to do to get the catalytic converter test to complete on my 1997 5-speed 4-cylinder 2wd 4Runner.īefore I had seen your TSB, I had gone almost crazy trying to get the catalytic converter codes to set, because I was following test #5 and #6 of THIS test procedure: There is a TSB that describes the drive cycles required which I have attached below
