Anyone else have problems with eps?

If you think it is doing it while the car is in acc then you are mistaking it for something else.

I'm not sure what manufacturer made the abs components on this car, guessing honda because they are still stock. I know it is the abs system because that is the only thing that feels like that on the brake pedal, it is like a turning gear is hitting the brake pedal and causing that very familiar vibration through it. I am wondering if it is the self check system as i believe on this car it does an abs self check a certain amount of time after the car is turned on, and if i turn it off and then back into the on position then it would theoretically reset the circuit and run another self check and perhaps i am braking sometimes when it is self checking? I mean the abs should be working when the ignition is in the on position correct? The eps does a reset and then works, the air bags work, the radio works, the speedo works, why would the abs and ebd be the only electrical systems not to function after the circuit is reset?

In my opinion the simplest way to kill your engine without having everything reset would be to "kill" the coil - i would find the power wire going to the coil and put a normally closed relay in that line - run a small switch to activate the relay to put an open in the circuit - this only kills the spark - everything else works the same (if you want to restart the engine just release the relay and you would have spark again- if the engine were turning <vbg>)

I have 4 coils, but I checked my schematic, and they all have a common ground. that may be the easiest thing to do it cut the ground...

That should work - anything to break the power circuit to the coils (if you power the relay from an ign hot wire and have it latch open with a push button the relay would go back to it's n\c position when you turn the key off) be kind of nice to have a push button that would kill the engine but reset it's self when you turn off the key so all you have to do is start the motor normally

You are correct. If you feel a puslation in the brakes after you put it back into ignition then it is the self test mode that all slip control modules do when they get ignition power again. If it only happens after you turn the key back to ignition then you will get a pulsation of all coils (8 if it is ABS and 13 if it is brake TC/ESC) along with a running of the motor.

FYI, no vehicle manufacturer maks their own ABS or ESC units. They are all from Tier 1 suppliers that specialize in this unit. Cost and speciality are the main reason. I am not aware of any aftermarket replacements either, not really feasible but everything is possible with the right time and money.
