John Deere transmission calibration power quad transmission. Using the early type command centre display.

Please find the instructions below for John Deere trans calibration via the old style Command Centre:

CAUTION– Tractor May Move Unexpectedly During Calibration. Ensure You Do Not Leave The Cab. The Area Is Made Safe And No One Is Near The Tractor.

General Safety Preparations:

1. Ensure that the tractor is parked on level ground.
2. Move the reverse drive lever to the neutral position, the range shift lever to the park position, and disengage the hand brake.
3. Start the engine.
4. During calibration, run the engine speed at 2100 ± 50 rpm.
5. Heat hydraulic oil to a temperature between 55°C (130°F) and no more than 70°C (160°F).

 

Entering Calibration Mode:

To access the Address List, you use the buttons and thumb wheel on the side panel. Follow the steps mentioned below to navigate through the Display menus:

 

1. Use the thumb wheel or the touch screen to highlight the display tab for the message centre page, and then press the enter button.
2. Use the thumb wheel or the touch screen to highlight the display tab for diagnostic addresses, and then press the enter button.

 

To enter technician mode (Service Level), press the display tab for diagnostic addresses again and hold it for 5 seconds. When you are in technician mode, you will see a T displayed beside the drop-down menu. If you cannot enter technician mode, press and hold the display tab for diagnostic addresses for a longer period of time.

 

Preparations for Transmission Calibration:

Select Module PTQ and enter

Navigate through the address list to PTQ037

 

IMPORTANT: If the transmission is to be calibrated with the Command Centre, the value in address PTQ037 must first be changed and then set back to the Original value. e.g.: Change 0 to 1 and save, then access the address again and reset 1 to 0 and save. Basically you are just changing this value and then setting it back to the value you started with. This lets the module know you have set the oil specification value. This step MUST NOT BE SKIPPED.

 

Follow the instructions below to prepare for transmission calibration:

1. Access address PTQ 038 and start calibration.
2. Use the selection wheel to select address PTQ 038 and press the confirm button. The Calibration Process Begins

 

John Deere trans calibration Information:

The display shows calibration information. Please follow the instructions below:

– Command Park: You Must move the range shift lever to the park position.

– F: You Must move the reverse drive lever to the forward position.

– N: You Must move the reverse drive lever to the neutral position.

– Command Not Park Range: You Must move the range shift lever to Range position A.

– R: You Must move the reverse drive lever to the reverse position.

– EOC: You Must select the selection icon and press the confirm button. Calibration values are saved.

 

Display Meaning:

– tCAL: Calibration is currently not activated. Calibration can be started by pressing the confirm button.

– CAL: Calibration is in progress.

– Abr: Transmission calibration has been cancelled by the user. The user pressed the back/cancel button.

– Oil: The oil type has not been set before calibration. This can be done in address PTQ 037.

– Oil OOR: The hydraulic oil temperature is not within the required range of 55°C – 70°C.

– SPD: Calibration aborted. Either wheel speed or transmission shaft speed has been detected.

– CLU: The clutch pedal has been actuated during the calibration. Calibration is aborted if the clutch pedal is actuated several times or for more than 4 seconds during the calibration.

– Eng: Engine speed is out of range. Set engine speed to 2100 rpm ± 50rpm.

– Err1: Transmission enable pressure has been detected during the control software initialization. Calibration is aborted.

– Err2: No transmission shaft speed has been detected at the beginning of the calibration.

– Err3: The brake pedal has been actuated during the calibration. Calibration is aborted.

– Err4: Calibration has been aborted. Perform the calibration again.

– Err5: Calibration has been aborted. Perform calibration again.

– SPD: No speed has been detected during the transmission output speed sensor test. This inhibits the calibration. B104 – Transmission Output Speed Sensor.

– N: The calibration requires that the reverse drive lever is in the neutral position.

– F: The calibration requires that the reverse drive lever is in the forward position.

– R: The calibration requires that the reverse drive lever is in the reverse position.

– P: The calibration requires that the range shift lever is in the park position.

– A: The calibration requires that the range shift lever is in position A.

– CAL-and– – -: The calibration is paused for 1 to 3 seconds to stabilize the system between the consecutive steps.

– F F: Calibration has been aborted.

– F S: Calibration has been aborted.

– F H: Calibration has been aborted.

– F L: Calibration has been aborted.

– F D: Calibration has been aborted.

– R F: Calibration has been aborted.

– R S: Calibration has been aborted.

– R H: Calibration has been aborted.

– R L: Calibration has been aborted.

– R D: Calibration has been aborted.

 

Please refer to the above instructions and display meanings for successful transmission calibration.
