ok.....sooooooo i dont think anyone on this board has realized that nissan made it possible to reset the ecu w/o having to disconnect the battery and without the use of a scantool.
so this is how you reset the engine ECU
i had to reset becuase i cleaned the TB throttle body and i messed up the idle control sensor.checkengine light came on.....
i sat in the car for like 40 mins trying to remember how i reset the maxima ecu......finally remembered....here it is.
1.)turn the key to the on position (do not crank over the motor....dont start the engine)
2.) wait 3 seconds.... and then fully step on the gas and let go fully 5 times with in 5 seconds....
3.)wait 6seconds....(not steppig on gas pedal)
4. FULLY PRESSS down on gas pedal and hold for about 10 seconds.
5.) the check engine light should be flashing.
should be flashing 10times and stop a few seconds and then 10 and stop.....etc.
6. hold down pedal again 10 secs.
7. release pedal.....turn key off.....
8...wait a few seconds and turn the motor on.....check engine light should be gone.
Further research indicates that you can indeed pull the code with no tool using this technique. The first flashes are slow, This is the first flashes are the first number in the code (thousands column). The groups of faster flashes coorespond to other numbers in the code. Between each number in the code, there is a pause. Ten flashes equals a zero.
