Fuel Economy & Power - The great balancing act...

Would this process be the same for the renix pcm. I only ask because renix throws live date through the pcm not stored codes.

Oh- you meant disconnect the positive cable AT THE BATTERY, probably should have clarified that.

I don't think so. The reset procedure was for a TJ, and the TJ wasn't born until 97.

I'm fairly confident that this is for OBDII only.

Do you routinely disconnect the positive cable anywhere BUT at the battery?

 

[JJacobs]

only when changing the starter... nevermind.

I agree. I don't see how placing the 12v+ to ground would do anything but short the battery. The 12v- is connected to the engine and frame and is for all practical purposes the same as the 12v- on the battery. Shorting the battery for 30seconds is, well, buying a new battery. It is a short in any terms. I can't see how this would clear anything in the PCM. I have an Associates degree in electronics and this defies all logic.

So I guess this mean an assc. in electronics, means you don't know sh*t about electronics. No connection to a +12V means no power, which means no possibility of short. You need power need a positive connection to short it out.

How about your Associates Degree explains to me where in the world a vehicle has a 12v-? The 'ground' is 0v and the postitive is 12v+. If you have 12v- at the frame you'd have a 24v total...
