I just finished writing an OBD II reader program for the ELM chip and I now need to test the Mode 3 and 4 functions for it that query and reset trouble codes.

Anyone know of an easy way to create a trouble code in the g35 so I can test reading and resetting the trouble codes?

Preferably something easy to do that won't actually break anything in the car.

 

disconnect the MAF sensor plug will do the trick.

god_of_cpu,

ELM = ?

If you want an easy way to bring in one or more DTCs, disconnect your MAF Sensor and start the engine. Immediately stop the engine and reconnect the sensor. Re-start the engine and you should see the SES light.

Your ECM should be at least one DTC. Most likely you'll also have a 1st trip DTC, Freeze Frame Data, 1st trip Freeze Frame Data. I don't think this will bring in a 2nd trip... or "Two Trip Detection Logic" code. Hopefully you will have the STR code.

Good luck.

Thanks, I'll try to disconnect the MAF once I go home.

The ELM is a chip that is used to interpret OBD II data directly from the OBD II BUS and turn it into a more convienent ASCII format capable of being read by PC serial ports.

See this thread for more info on the chip and how to create a circuit. http://www.mp3car.com/vbulletin/show...734#post200734

You can also purchase the circuit at www.scantool.net

 

Leave the gas cap loose?

That is what I was gonna suggest. I just had my SES light
come on because I left the gas cap attached to the door
instead of on the gas tank. Our Gs will sense this and throw
on the Service Engine Soon light. It will take a few drive cycles
for it to be detected.
