Premium Tech Tool Calibration functions 

 

1 - Service and maintenance

 

2 - Engine, Engine mounting and equipment

                25536-3 - Variable geometry turbo, calibration

This operation is used when the turbo actuator is being installed onto the turbo, such as during actuator replacement, or re-installation of a previously removed actuator.Installation of actuator: Before the actuator is installed onto the turbo, the actuator's output pinion must be placed in the proper installation position. This position corresponds to the installation position of the sector gear on the turbo. Refer to service information for details concerning proper positioning of the turbo sector gear.Calibration of actuator: After an actuator has been installed onto a turbo, calibration must be carried out in order for the normal range of travel to be established. During the calibration, the actuator moves the turbo nozzle from one end stop to the other in order to define the normal range of travel. The calibration data is saved by the actuator to be used in self-diagnostic checks during normal operation.Calibration complete: Fault codes are read after calibration to ensure that the actuator was calibrated successfully. A green indicator is shown when the calibration is successful. If the indicator is red, the calibration failed. In this case, start again and run the operation once more. If the calibration fails a second time, fault trace according to normal routines for MID 128 SID 27 FMI 9.

                25833-3 - SCR, SCRT freeze monitor, calibration

The injection module can be damaged if it freezes, either with or without AdBlue solution in it. Two counters are used to monitor this.

The first counter (FCC1) detects:

if the system has been drained of AdBlue after the last running cycle.

if it has started at a temperature below -10 ºC.

The second counter (FCC2) detects:

if the system has NOT been properly drained of AdBlue after the last running cycle.

if it has started at a temperature below -10 ºC.

When either of these counters has counted up to a preset value (FCC1 = 5000, FCC2 = 20) a fault code PSID 89, FMI 14 is set.The two counters are to be read off at a workshop to determine when replacement of components should take place. However, at least one of the counters must have passed its predefined value before replacement of components.The counters shall be reset when the dosing module and/or other parts of the system ave been replaced.
