Your car has an ECM/HCU software mismatch. One if those two modules is at baseline 535 and the other is at 520. Reflash the HCU and ECM to the same baseline. Drive 2 drive cycles STARTING FROM COLD. A drive cycle with a warm engine will not run the 02 and Catalyst monitors. After the SW is fixed, Start from cold and run in sport mode on the highway maybe a 10 minute drive without AC if possible. Then let it cool COMPLETELY. Then repeat. DONE. Guaranteed. Trust me we chased out tail for weeks with this problem on one of my customers cars. I've fixed at least a dozen around the country with same issue.

It hooks up to the OBD 11 access port under the dash near the driver’s left knee. You WILL have a check engine light at some point. When you do you will be able to read a code and at the very least be able to give valuable information to your service center. Once you perform a hard reset to get your car back on the road that information will be gone. After clearing your check engine light or disconnecting the 12v battery the Karma engine management system will run a series of checks to make sure the emission system is functioning properly. There are three main monitors that need to be cleared, the Catalyst, the Oxygen Sensor and the Evaporative System. The car will clear the monitors after going through a number of varying drive cycles. It can take a very long time for this to happen randomly. I have had the best luck using the following system:
-> Hook up your OBD II reader under the dash and scroll to monitor checks, I/M.
-> Leave it hooked up while you are taking the car through the drive cycles so you can tell when the monitors are cleared.
-> All driving should be done in Sport mode.
-> It is critical that the car have between a quarter and three quarter tank of gas.
-> Warm up the engine until it shuts off at a stop. Turn the car off and let it go to sleep.
-> Start the car and drive continuously between 55 and 60 mph avoiding hills where possible. The Catalyst and Oxygen Sensor monitors should clear. It may take up to two or three of these drive cycles.
-> Once they have cleared take the car home and park it over night. In the morning perform the same drive cycle. The Evaporative monitor usually clears on one drive. If not, do it again.
In California most of our Karmas are due for their first smog checks this year. At some point you will need to use this. If you have questions feel free to pm me or call the shop.
