My treadmill runs for 9 secons and stops and shows E1

Ok. So the first thing to try is to calibrate the speed.
You do this by doing the following:
  • With the SAFETY KEY in place, hold the ELEVATION UP and SPEED DOWN buttons for five seconds. The console will beep twice, "ENG0" will appear in the Distance window, and a number will appear in the Elevation window.
  • Press SELECT until "ENG3" appears; this is for Auto-Calibration.
  • Press START to Auto-Calibrate.
  • The treadmill will calibrate minimum and maximum speed, and minimum and maximum elevation. When Auto-Calibration is complete, the treadmill will reset to User's start screen. This process takes three to five minutes.
Make sure there are no errors. . .and that the speed goes from super slow to super fast and then stops. . .. if it stays slow. . or stays fast. .or error code appears during calibration, there is a problem.
If after a good calibration sequence, if it still does the stopping and E-1 after 10 seconds. ., then you need to (Power off and disconnect treadmill). . .then unplug the speed sensor from the lower power board, blow into the connector on the wire, and add a little contact cleaner spray to the connector on the board.
Recap: If it actually runs. . .but stops after a few seconds. . but the calibration runs and passes fine. .. .more than likely it is a speed sensor misread or a faulty speed sensor.

Run the software calibration for easy troubleshooting and fix it. God bless you
Calibration for "Newer Style" Consoles

The Calibration sequence can generally be used to accomplish the following: 1) To reset the treadmill's speed software, if the running belt seems to be moving faster or slower than the speed indicated on the console. 2) To reset the treadmill's incline software, if the walking deck seems to be elevated higher or lower than the height indicated on the console. 3) To synchronize the treadmill's electronic package ANY TIME a replacement part (anything electrical) has been installed and is being prepared for use. 4) This should be the first step performed when attempting to diagnose or troubleshoot the unit.Calibration often helps in correcting minor "bugs" in the software (by "resetting"), before actually having to replace components.

Before You Begin:

You must first determine the model number and style of unit of the unit being worked on. Do this by:

  • Powering up the treadmill and removing the emergency stop key (usually a magnetic plastic piece that attaches to the top, center of the console). If you see "10" in the console, it is an old style console and the "Older Style" Calibration should be referenced. If an "SI-1" appears in the console, it is a newer console. The following calibration sequence can be performed.

Note: To change any of the current codes (if incorrect or out of sync), use the SPEED + or SPEED -(minus) button(s).

Refer to the Calibration Chart (or the unit's owner's manual if not on the chart) to verify that the calibration codes on the unit (represented as "??" below) are correct.

The Steps for Newer Style Console Calibration

  1. Locate the calibration area on the rear or underside of the console (a hole, near the console's center, that goes through to the electronics board. (This hole should not have a screw in it.)

  2. Insert a pencil (eraser end), into the hole and feel around for the cal button (will click when pressed).

  3. Press the button 2 times (with the pencil eraser). The first click should show CL11 in the console, the second click should show CL21.

  4. If the process was done correctly, and CL21 appears in the console, you are in "calibration mode." The next few steps consists of pressing buttons on the console and observing settings. This will not require any other tools.

  5. Press ENTER. CL22 should display in the TIME window and (??) in the SPEED window.

  6. Press ENTER. CL23 should display in the TIME window and (??) in the SPEED window.

  7. Press ENTER. CL24 should display in the TIME window and (??) in the SPEED window.

  8. Press ENTER. CL25 should display in the TIME window and (??) in the SPEED window.

  9. Press ENTER. CL26 should display in the TIME window. You should then see the letter "E."

  10. Press ENTER. You should see "SS" or "55" in the console.

  11. Push the STOP/START button. For safety, at this point, you should step off, or be off, the treadmill.

  12. Push the ENTER button. The walking belt should start to move, accelerate to maximum speed, then stop on its own.

  13. When the belt stops, the incline should self test by raising to its highest incline position, then lowering back down to its lowest position.

  14. Once the incline test is complete, push the POWER button 2 times. The unit should shut off and the console should go completely blank. If this happens, the treadmill is done calibrating and is ready for use.

  15. If the letter "F" appears in the SPEED or INCLINE window when the power button is pressed 2 times, the treadmill is indicating a failure somewhere either in the SPEED or INCLINE (depending on the window the "F" appeared in). Troubleshooting the failure would be the next step.

Engine stalls, p0720 engine light on. Runs ok than goes sporadic.

There are 2 possibilities here:
1.- There may be a problem with the new speed sensor, the electrical wiring between the speed sensor and the PCM, or an internal PCM problem. To see if VSS signal is present at the PCM a scan tool capable of displaying live data is required.

2.- There is a recall action on this model year for erroneous speed sensor signals; the cure is an updated software calibration. If your truck has not yet had the updated calibration installed, you should call your local Dodge dealership with your VIN number and ask the service department to check to see if there are any open recall actions on your vehicle. If the software calibration has not been updated yet, they will perform this procedure free of charge for you. If you do not have the current software calibration in your PCM to correct the VSS issue, you need to have this done before proceeding any further with attempting to diagnose this problem

This sensor is located at the rear of the transmission.

When Monitored and Set Condition: P-0720 LOW OUTPUT SPEED SENSOR RPM, ABOVE 15 MPH

When Monitored: Continuously with the key on, engine running, and gear selector not in park or neutral.
Set Condition: This code is set if the vehicle speed (as determined from the vehicle speed sensor), is above 15 MPH, and the output shaft speed is below 60 RPM for 2.6 seconds.


Hope helps.

I have a MC2100-12A motor controller in this treadmill. The LED blinks quickly like communication is ok but it doesn't control right.The speed sensor also looks ok. When 1mph is selected it runs at 2.7mph...

The speed sensor on these machines have nothing to do with controlling the speed. The machine will run without it. The sensor is obviously working, since you are getting a speed reading.
The calibration is a mechanical adjustment found on the motor controller, the instructions are found under the lid as well as the meaning of the LEDs flashes on the tech sheet..
Follow the calibration procedure. If the operation is still erratic, I would suspect a defective controller.
Calibration: Press stop and speed up. Install the safety key/magnet. release the buttons. Press stop 1 time. one window displays speed, the other the calibration number. Both should be "0".
Press speed up, the treadmill should begin to move around 25-30. increase to 85, the machine should be a max speed. adjust the pot on the motor board to max speed. Some machines are 10mph, others 12mph. The tech sheet will tell you the max speed. When adjusted, press speed down. the machine will stop. Now press incline up. That will calibrate the incline. When completed, remove the safety key.
If operation is still erratic, change the motor controller.. It could be the console, but the cost of replacement makes the repair in most cases uneconomical..

How do you do the wheel speed calibration? In the Nav setup options where you can reposition your vehicle it gives an option for wheel speed calibration but it say select after wheel speed calibration. How...

I don't know if this can help but try the following:
1- press the RPT/NAV Button untill you hear the beep.
2- hold the config button for arround 30 or 40s until you heard the beep, now a new config screen is opened.
3- try the 3rd button on the right as i remember, you will open a new screen where you can adjust the distance and the number of pulse(related to the Vehicle Speed Sensor).

4- don't try to mess with anything else like Memery clear or program Clear or anything else or i beleive you will lose the programming.
