How can I reset the computer?

There are a couple different levels that you may be talking about. The first low level relearn procedure is when the ECM is reset or the codes are cleared. It usually takes at least two ignition cycles and two days of driving for the ECM to come out of default. The other Relearn procedure can only be performed with a professional scan tool. Through the scan tool the user is able to reset fuel trims and a few other parameters. I hope this helps but if there is more to the question. Feel free to write back.

Dealer or mobile lock smith . unless you have a professional scan tool that can program keys . For about $1,500 you can buy a autel scanner . Immobilizer System Component Programming
10-Minute Immobilizer Relearn
This 10-minute relearn procedure will relearn the prerelease password and the challenge/response data between the theft deterrent module (TDM) and the engine control module (ECM).
Connect a scan tool to the vehicle in the pass-thru arrangement.
Turn ON the ignition, with the engine OFF.
Ensure that all power consuming devices are turned OFF on the vehicle.
On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions, using the Pass-Thru method. Ensure the correct programming selection is chosen based on component being replaced or programmed. For this procedure, go to the V.T.D. Vehicle Theft Deterrent Learn menu and choose the Vehicle Theft Deterrent Learn, ECM, or PK3 Replaced selection.
At this point the scan tool must remain connected for the duration of the 10-minute relearn procedure.
Important:
• The scan tool will initially display 12 Minutes. The first 2 minutes allow the scan tool to initialize the appropriate control module. The remaining 10 minutes is the relearn timer.
• On some vehicles the security indicator may be illuminated for the duration of the 10-minute relearn procedure.
Observe the scan tool, after approximately 10 minutes the scan tool will display "Programming Successful, Turn OFF Ignition". The vehicle is now ready to relearn the key information and/or the passwords on the next ignition switch transition from OFF to CRANK.
Turn OFF the ignition and wait 2 minutes.
With a master vehicle key, turn the ignition to the RUN position for 15 seconds, then start the vehicle. The TDM and ECM have now relearned the pre-release password and the challenge/response data.
With a scan tool, clear any DTCs.

do a search for Honda element throttle body relearn procedure. That's the term you're after, not a computer reset

try reading the FSM? yet

or at alldata.com for 15 bucks?

it all there, every day ,all the time. no need to wonder.

or join jeep forum.?

it unscrews,

and screws back on.

but the real question is, is it needing calibration. during or after.

replacing it is childs play, youtube that, bingo?

did you do all 25 test in the FSM, yet, on iRMC

even making sure the flapper is not jammed??????

if yes, and the actuator is really bad,

read this in the last page .



If the Manifold Flow Valve is replaced, a non volatile memory reset must be performed to learn the new port flap adaptive values.



now more lil\'horrors.. see what happens if you jerk the battery

quote

Vehicles equipped with engine and transmission computers may require a relearn procedure after the vehicle battery has been disconnected. Most vehicle computers memorize and store vehicle operational patterns. When the battery is disconnected, the information may be cleared. If the information is cleared, the computer will go into default mode in order to operate the vehicle. The vehicle computer will relearn operational patterns each time the vehicle is restarted. The relearning process may take up to 40 or more key cycles.

When a specific engine component is replaced, a relearn procedure may be required. If the relearn procedure is not performed, the vehicle may exhibit the following:

• Harsh or poor shift quality



• Poor fuel mileage



• Hesitation or stumble



• Unstable idle or stalling



• Lean or rich running conditions

If an accessory component was replaced, a relearn procedure may also be required. The following systems and components may not work properly without a relearn procedure:

• Anti-theft system



• Steering system



• Power window system



• Power sunroof system

It is important to reset any Diagnostic Trouble Codes (DTC\'s) before performing the relearn procedure. Most relearn procedures can be performed with the use of an OBD-2 scan tool.






NOTE




This reconnection procedure is to be performed anytime the battery has been disconnected.

1. Connect the battery negative cable to the battery post and tighten the clamp nut to 45 inch lbs. (5 Nm).



2. If the vehicle is equipped with Electronic Stability Program (ESP), once the battery is reconnected, the Steering Angle Sensor (SAS) in the clockspring needs to be calibrated.
   
   
   
   
   NOTE
   
   
   
   
   The SAS requires calibration anytime the battery or an ABS (ESP) component has been disconnected for any length of time. If the SAS is not calibrated following battery reconnection, the ESP/SAS indicator lamp is illuminated following 5 ignition cycles indicating the need for calibration.
   
   
   
   
   



3. To calibrate, perform the following:



4. Start the engine.



5. Center the steering wheel.



6. Turn the steering wheel all the way to the left until the internal stop in the steering gear is met.



7. Turn the wheel all the way to the right until the opposite internal stop in the steering gear is met.



8. Center the steering wheel.



9. Turn off the engine.

SIGH !

Try this theft relearn procedure....
Chevy Malibu Theft Relearn Procedure
If it does not work, you may need a new ignition key cylinder.

Reset for the key
10 minutes on, then 5 seconds off. Then start.
Relearn procedure is the same except you do it 3 times.
Have a charger on it for the relearn.

relearn procedures are only done with atech 2 scan tool

Have the computer re-flashed

manufacturer does not provide a specific computer relearn procedure for obtaining proper driveability . if the battery was disconnected or replaced , driving the vehicle will enable the computer to preform a relearn procedure for obtaining proper driveability , driveability may differ from what you are used to until computer has fully completed the relearn procedure . cheers
