patryk9pl · Answer

Checked. From the gearbox to the brown connector, supply PC or PT, I don't remember now. Only that not all the cables go there. There are probably 3 more cables in the box and I don't know where they go. I didn't have time to take it apart. And where is the Transmission Control Module?...

keicam1991 · Answer

Check power and ground.

Hello I have the same problem, please help: e-mail maciek(_at_)grupairma.pl

There are body grounds under the fuse cover in the cabin, check if they are well grounded.

Macio782 · Answer

The entire harness from the electronics of the gearbox to the front cabin has been examined

This is the only error, apart from that the gearbox has a problem with the 7th gear, it does not engage the first time after dropping the revs, it engages with a grinding sound

citromaniak · Answer

As I wrote, check all the masses carefully because it was a problem for one guest. Not one service center was concerned about this error.

citromaniak · Answer

Maybe some synchronizers have failed, I don't know, maybe someone who disassembles ishifts will tell you.

Macio782 · Answer

Weights ok... the error is still there

TomasAGC · Answer

You won't get very far if the shift to 7 grinds, a standard fault with this gearbox, it's better to fix it - it fell off, the synchronizer broke and it's probably rubbing against the housing after you've been driving with it for some time. Don't rush yourself, because even to remove the selector you will have a long way to go.

Macio782 · Answer

But why the error mid 130 psid 232 fmi 9???

TomasAGC · Answer

I won't answer this question, but I've seen this error in cars where everything worked properly and were calibrated. If I were you, I would take care of the grinding noise and leave the cables for later.

Did you diagnose the gearbox with a computer or manually?

Added after 3 [minutes]:

In I-shift, synchronizers for half gear/overdrive and high/low gear for r/1/2/3, lack of synchronization inhibits the roller brake.

Macio782 · Answer

Error based on the car's computer display.. computer connected and gear change diagnosis successful

Anonymous · Answer

Calibrate and check. When the gear does not engage, errors in the memory remain inactive in Volvos made around 2007 and above and cannot be read manually.

It will be rather a trivial slider.

Macio782 · Answer

I have it in a Magnumka 480DXI, 2011, mileage 590,000

Anonymous · Answer

7th gear, if I remember correctly, is a jump from a small to a large gearbox and the reducer synchronizer will be damaged - a common occurrence in these years. The back of the box needs to be removed and the torn off sheet metal will be visible.

Hektar Zahler · Answer

Enough of that !! No one has any idea what he's talking about. The actual reason for the error is: waiting for the default message exceeds the reception time limit. Preliminarily check the cables, connectors and resistance. Next, we need an electronics technician.

Anonymous · Answer

I wasn't considering the error but the grinding noise of the run. The lack of communication does not affect the grinding noise of the gear.

citromaniak · Answer

Everyone can say it in slogans. Be specific about which wires, because as you know, there are kilometers of them put together.

Hektar Zahler · Answer

Are you serious or do you really not know? CAN control twisted pair upper right corner of cabin connectors (standing facing the cabin) on the right. @piotr I see that you don't understand the topic because you haven't seen the transmission distortions in Volvo. It is the complete lack of error history that is now the biggest problem, because PSID 232 is like a confirmation that the controller had the right to blame the errors associated with these distortions, or (what is important!!) not register them at all, quote: Never clear errors in this car again.

citromaniak · Answer

The guy said he checked the harness from the gearbox, so your theory is out of the question. Let's just hope he checked with a bulb and not a meter.

Hektar Zahler · Answer

You keep getting lost, because as if you didn't know, this section doesn't have to be damaged, because no error indicates it. Watch what I say and stop spreading confusion immediately.

citromaniak · Answer

This error indicates missing frames in the Can network between ishift and the engine controller

Hektar Zahler · Answer

You're still wandering. This is something like a warning that determines CAN errors. The default message goes out from the cab to all controllers. In case of PSID 232 corruption, FMI 9 has the same right to be thrown out by each of them. Such a diagnosis based on error codes requires an error history.
