This function is generally located in the Injector calibration/coding section under Utility or Special Functions. Note: PILOT QUANTITY LEARNING may also be titled “SMALL QUANTITY LEARNING” or “LEARNING” depending on the scan diagnostic tool used.

Using your scan diagnostic tool, open the function “PILOT QUANTITY LEARNING” to carry out the injection pilot relearn.

INJECTION PILOT RELEARN FOR SOME LATE MODEL VEHICLES Once the vehicle has been run and shutdown, a CEL or Glow Plug light will illuminate on the dashboard until the injection pilot relearn has been carried out. This is carried out using a scan diagnostic tool after the injectors have been coded to the vehicle and fitted to the engine. Toyota 1KD Hilux/Prado and Mitsubishi 4M41 Triton/Pajero) an injection pilot relearn will need to be performed in addition to the coding of each injector to the ECU. If the injectors have been incorrectly ordered and installed to the vehicle, a return for credit may be declinedįor some later model vehicles (e.g.

Please note: We recommend coding the injectors PRIOR to fitment to the engine, confirming the correct injectors have been supplied.

If you continue to have acceptance issues with your scan tool, please contact a staff member from Denco Diesel & Turbo who will troubleshoot the problem.

If the correct vehicle has been selected, check that the calibration code hasn’t been misread or entered incorrectly – it only takes one digit to be incorrect for the calibration code to be rejected. If the calibration code is not accepted, check that the correct vehicle (make/model/production date) and ECU manufacturer has been selected in the scan diagnostic tool.Using your scan diagnostic tool, enter the new calibration code of each injector into the correct cylinder.Mark down the calibration code of each injector found on the solenoid and record which cylinder it will be fitted to.CODING THE INJECTORS PRIOR TO FITMENT TO THE VEHICLE

It is also recommended that the vehicle is given at least one full day of running through a range of operational conditions to allow the replacement injectors to learn the new operational characteristics. When working on vehicles and replacing injectors, the battery (or batteries) must be disconnected as the ECU will retain memory of the previous state and fail to relearn the operational characteristics of the replacement injectors once installed.
