various calibration procedures

Reset & Calibration Procedures

Throttle Calibration

Throttle calibration can substantially improve throttle responsiveness over "factory standard." Many people notice what appears to be sluggish throttle response or a "dead area" at initial accelerator depression. Throttle calibration can take care of these.
1) Insert ignition key and turn to "ON" (not start).
2) Wait for all idiot lights to go out. Check Engine Light may remain on.
3) Slowly depress the accelerator pedal all the way to the floor.
4) Slowly release the accelerator pedal until it's all the way back up.
5) Turn the ignition key to "OFF".
6) Start the engine.
Most drivers notice an immediate change in throttle response, but depending on your driving style, you may need to repeat this procedure periodically due to the computer's adaptive programming. You likely need to repeat this procedure any time the battery is disconnected.

MDS Reset & Calibration

1) You need a fairly long, open, safe, straight road for a WOT run to about 35 mph.
2) Get engine up to operating temp, engine running and car stopped place gear selector in "[D]". Bump it to the Left until in "[1]".
3) Turn off all electrical accessories (except lights if needed).
4) Make a WOT run to 4500 RPM (about 35 mph), immediately remove foot from accelerator and do not depress the brake, let the vehicle coast with the throttle closed until the vehicle speed is again at 35 mph or lower.
5) Stop vehicle and place in "Park", verify all instrument cluster warning indicators are off.
6) Cycle ignition switch "Off" and back "On", but do not immediately start engine.
7) Hook up StarScan and clear DTC's
8) MDS calibration is now complete.

Auto-Up Front Window

If the vehicle is equipped with the Auto-Up feature, the door module needs to be calibrated upon reconnecting the battery. This module requires calibration if the battery or door module has been disconnected for any length of time. To calibrate, perform the following steps:

1) Connect the battery cables.
2) Using the window switch, raise the window to the full UP position. Hold the switch in position for 1 second, then drive the window all the way down to the bottom.

Electronic Stability Program (ESP)

If the vehicle is equipped with ESP, once the battery is reconnected, the Steering Angle Sensor (SAS) needs to be calibrated. The SAS requires calibration anytime the battery or an ABS (ESP) component has been disconnected for any length of time. To calibrate, perform the following:

1) Start the engine.
2) Center the steering wheel.
3) Turn the steering wheel all the way to the left until the internal stop in the steering gear is met, then turn the wheel all the way to the right until the opposite internal stop in the steering gear is met.
4) Center the steering wheel.
5) Stop the engine.

Sensor Diagnostics Display (Requires EVIC!)

If you have the Electronics Convenience Group option, you can enter a diagnostic mode and cycle through various displays, such as oil pressure, pedal position, and software version, to name a few.

To enter diagnostic mode (refer to your steering wheel controls), depress and hold the compass button (the one with the N and small arrow above it) and musical note button for about 6 seconds with the key in the ON position (doesn't matter whether or not the engine is running). Hold the buttons until you see the display change.

Cycle through the displays using the up/down arrow buttons. Exit diagnostic mode by depressing the compass button.

Display OBD-II Trouble Codes On Cluster (Works with or without EVIC)

1)Get in the car, close the door. Perform steps 2-6 fairly quickly (less than 3 seconds total time). (The key should not return to the OFF position throught the sequence!)

2) Turn key to 'ON' position
3) then back to 'ACC'
4) then to 'ON'
5) then back to 'ACC'
6) then to 'ON'

If there are any stored codes, they will appear immediately, in place of the odometer. For instance an "INTAKE AIR TEMPERATURE SENSOR CIRCUIT HIGH" error will set a code of P0113.

Once the codes have been displayed, you'll see "-----".
If there are no trouble codes, the dashes will be the first item displayed.
After a few seconds, the display changes to "-dOnE-".

Cluster Range Diagnostic.

1) Be sure key is set to the 'OFF' position.
2) Press and hold the 'Trip Meter Reset' button.
3) Turn the key to 'ON' position.

The gauges will step through the whole range. If your gauge is acting funny, this is an easy way to see if it's the sender or the gauge.

Display Engine Operating Hours

1) Turn the key to the 'ON' position
2) Press and hold the 'Trip Meter Reset' button for approximately 6-8 seconds.

The engine operating hours will display. Divide this by your odometer miles reading to discover your average speed over the life of the car.

cool beans...whoever tries these out on our Patriots first needs to report back as to how they all (or some) work.

Thanks, terasec.

Ive had my battery disconnected many times for hours on end and have never needed to recalibrate the SAS or the Window.
