MAN TGX 18.440 - comfort shift defective , adblue

Hi, I have MAN-ika 18.440 2009 on the tray. Namely, the error with comfort shift and adblue pops up. In comfort shift I can not diagnose tex defect, I have no idea what to look for, and adblue error 5533 sensors have resistance when heated from 200-650 ohms, in the parameters pops up that the sensor before the catalyst voltage is 5.04 V. What to do where to look

Buddy having a computer you still have to be able to use it ...

First of all, you do a general check (which can be seen on the screens) without providing numerical codes, general control will not always show faults from all systems and there is no full description.

Secondly, for adblue long codes will be signaled (in yellow) despite the working system and you will not delete them.

Fault shift comfort diagnose in FFR there you will also have parameters, etc.

There are no errors in FFR, the coupling was calibrated

 A mistake came up. Entry comfort shift inputs cs1 and cs2 error 3250

The push-button does not contact or break the circuit. With Texe, you can easily test!
5533 is a fault in the NOx sensor (heating) and what FMI?

And where is this NOx preheating sensor

 In FMI there are no errors, but he showed up in FFR 03250. And there are several of them in GDK / PDF

NOx sensor heating failure is related to several FMIs or missing signal or interrupted circuit or temperature not reached, etc. Everything is written on the instrument panel, even the time of the failure. FMI is the identification of the type of fault !!! Short circuit break failure signal failure component malfunction etc. .... Have a nice weekend

Buddy FMI are not bugs but abbreviations and mean Failure Mode Identifier serwis_gh gave several options of the FMI type and so to each error code FMI is added.

The error you give from the FFR is the same as the FMI ... but since you have a computer, as I wrote earlier, enter the FFR. See the states of comfort shift switches cs1 and cs2 (change of status with the grip) the grip can be measured with a multimeter.

As for the GDK / PDF vulnerabilities, please provide everyone with information whether the code is active or not and this is also important.

NOx heating refers to the NOx sensor itself (internal structure)

Buddy, if you do not cover the above things with all due respect but leave it to the electronics engineer and deal with the mechanics (according to specialization) you will save time unless you want to learn but it will take a lot of time and I do not write it maliciously.

I have already checked the handle of the transition. FFR error is 03250-08. And I just want to learn from the better

 As you said, I checked in the comfort shift parameters the button works, but I do not want to activate the clutch

I think you know that comfort shift works while driving, over 10 km / h.

I've improved my spelling. I pay attention to write posts flawlessly.

Yes, I know, but where to look for the fault?

Maybe it's worth checking the beam between the grip and FFR ??
Clutch you write that it was calibrated. And the clutch sensor is working properly ??

A driving connection as the car returns from the route.
And the sensor works correctly, the value shows ok.

I hope you have correctly checked the comfort shift button. You have 3 wires and a button from one connection must turn on the next ... and disconnect previous ones, i.e. "transition" changes from pin to pin after pressing the button.
Your error is closely related to the button circuit malfunction.

For sure the wires are good and the knob too

buddy svavecone it turned out that it was a cable in the knob and once connected once not. But now Adblue has been jumped error 03673-08 something with the line can only what ??

System reaction: Slave control device blocks the amount of fuel injected, the engine continues to run with one row of cylinders (half power)
Note: For EDC7, C32 Master / Slave is connected to M / S-CAN (connection between master controller and slave controller) on pin A27 and pin A45. In the case of an EDC7 C32 in-line engine with the MAN AdBlue A-CAN system (CAN for additional flue gas treatment), it is connected to pin A27 (lead 191) and pin A45 (lead 192)

He also wrote but in small letters ...
