1996 to 2002 Toyota OBD II Catalyst Monitor Readiness Drive Patterns

The catalyst monitor on many Toyota vehicles can be difficult to complete.  That’s why it’s important to follow the Toyota recommended drive cycle after performing actions that are known to clear your Toyota’s computer memory.

Remember, all on-board diagnostic monitors are cleared when the battery is disconnected, or when the power train control module (PCM) is cleared with a scan tool.


  1. Do not turn off the ignition switch during the test procedure.
  2. Allow the vehicle to run at idle until warmed up.
  3. Drive at a steady speed between 40 and 70 MPH for 10 minutes.  It’s a good idea to stay in the middle of this range, so 55 MPH is optimal.
  4. It may take several attempts and warm up cycles to complete the drive cycle.

Star Smog Check: Aston Martin Vanquish & 1978 VW Bus


Our smog technicians are inspecting two very different vehicles. The Aston Martin Vanquish passes it’s star smog check. Unfortunately, the 1977 Volkswagen Bus does not. It is sometimes difficult for older vehicles to conform to the strict smog standards set out by the State of California. On the bright side, California offers subsidized smog repairs for low-income motorists. There is also a vehicle retirement program that will give you cash for your “clunker.”
