Communication with SANDEN Electric Compressors Models 33H4166 & 33L4156 for Hybrid Vehicles

Hello

I am looking for software or a way to communicate with SANDEN electric compressors.
It's about clearing the error of too much current consumption (after repairing the inverter / motor)

model 33H4166 - fitted to Volvo V60 hybrids
model 33L4156 - fitted to the Mercedes W213 hybrid

Either you can do it after CAN, or you have to rummage in EEPROM by connecting directly to the procek.

Maybe someone knows if these compressors have the same ID in CAN communication and are interchangeable between cars?

Any hints are welcome.

Regards
GREGOR

And in the car it's not going to delete, I doubt it.

I don't care if it's on the table or in the car.
Just tell me what. VIDA does not have such an option.

The compressor (ACCM module) has a "failure" status, i.e. to be replaced.

I need to somehow inform ACCM that it's fixed - like from the factory.

GREGOR

Is there anyone from Wawa, Żyrardów, Skierniewice, or the surrounding area, who has equipment for reading Renesans R32C R5F64213KBF procs?

I need to dump the contents of the EEPROM from the processor soldered to the board. It has a 10pin pin next to it, visible in the photos from the first post.

GREGOR

I'll answer this myself, maybe it will be useful to someone.

Merc's compressor electronics respond to CAN traffic with addresses 001, 200, 2d5, 400, 6ca.
For a packet with the above address, it sends back messages to the following addresses: 419, 3d2, 28f

The ACCM module in Volvo has the address 7c7.
All other addresses in Volvo have 7xx addresses.

Conclusion: modules are not interchangeable.

I dug around in VIDA and found an option to reset any module.
SOFTWARE->ADVANCED-> select the module, then press SEND PROG and SEND RESET.

GREGOR

Good day. I live in Ukraine. I bought a V60 Hibrid 2013 in the Netherlands. Two months after purchase, my air conditioning compressor refused. VIDA generated an error exceeding the current draw at high voltage. Tell me what exactly was fixed in the compressor?

Unfortunately, this is an electrical failure of the air conditioner caused by faulty software.

The IGBTs in the inverter are probably damaged.
You can replace the transistors on your own or send the compressor to the company for regeneration Auto Climate , the cost is approx. PLN 1,500 gross.

I gave up. I gave the car to an authorized service center for repair and update of the SERVICE 2.0 software.

The cost is PLN 5,000 gross in the promotion and after discounts. They gave 2 years warranty.
Unfortunately they took away the compressor so I couldn't verify the actual damage.

It should be borne in mind that in this car model, even when the air conditioning is turned off inside,
it is the air conditioning system that can turn on and cool the batteries in the trunk while driving.
The same is true when the car is stationary while charging. Sometimes the radiator fans in the front of the car turn on.
This means that the controller turns on the air conditioning and cools the batteries while charging.

If you repair and unseale the air-conditioning system yourself, remember that there is a special SP-A2 oil in this system and it cannot be mixed with other oils for mechanical compressors.

If anything, I have a working Mercedes compressor for sale. Electronics are incompatible. But there are 6 operational IGBT transistors and the entire compressor is mechanically and electrically functional.

GREGOR

Unfortunately, in Ukraine, the official service does not carry out repairs related to such a compressor (there is no certificate for high voltage). Such transistors are in Ukraine. how can the software damage the compressor because I didn't change anything in the electronics before the compressor crashed?

Volvo hybrids are still quite rare cars even in Poland.

You are welcome to Poland.

Autogala Warsaw

They have a smartphone app. You can ask for a price offer for the replacement of the compressor. Software update of the whole car - free of charge.

There are IKW75N60TA transistors in the Mercedes compressor.

The error in the software is that the controller gives full power to the motor too quickly.
The transistors are on silicone pads and thermally fail.

I hope that this has been corrected in the new software and the air conditioning will work for more than 4 years.

Regards
GREGOR

Thanks Gregor. I think I can update the firmware on the official service, but I will have to fix it myself.

pictured in the first Merc compressor? If I open the compressor, will I need new o-rings or can I reuse the old ones?

Good evening Gregory. Took the compressor off today. The winding rang - no short circuit, no break, no failure of the case. I haven't paired the transistors, but they ring correctly on the board. He is an employee

Desolder and remove the motherboard. Check the IGBT transistors if they turn on and off Vge=+/-15V.

You can check the compressor motor using the generator/starter (IGS) from the car:


What exact error are you getting on the volvo VIDA? number and description.

If the IGBT transistors are operational, then some other element has failed. For your convenience, a list of chips:

R32C R5F64213KBF - processor
v4274a - Linear Voltage Regulator, 400 mA
38p06 - what could it be?
22N055 - N-CHANNEL POWER MOSFET
TJA1041 - High speed CAN transceiver
LTDGX2L63 - what could it be?
AUIRS21814 - IGBT drivers
6242H - Dual/Quad 18MHz, Low Noise, Rail-to-Rail, CMOS Op Amps
2901 - Low-power quad voltage comparator
NCV8518 - Linear Regulator - LowDropout, Watchdog,Wake Up, RESET, ENABLE, proc power
UM1301 - Triple-Channel Digital Isolators
UM1402 - Quad-Channel Digital Isolators

error b102d92

reads as high voltage overload. current 9a

To niby taki sam jak u mnie.
A jakie wartości są w tabelce: "Frozen values from initial readout" ?
In-car temperature
Outdor temperature
High voltege supply A/C-compressor
Input current A/C-compressor
Requested maximum power consumption A/C-compressor
Maximum power consumption A/C-compressor

the stop sheet was not given to me. and now I probably won't see him. compressor removed

All information is stored on the VIDA computer in your car's profile. No need to read again.

In my "Input current A/C-compressor" it was 63.75 A

Send photos of your electronics board. Let's compare what's different.
What IGBT inverter main transistors do you have?
What is the compressor part/serial number?

g

I was told that the overload current was 9A (normal 5-6). On your recommendation, today I called the compressor, the generator is spinning.

The input filter in the compressor is a bit different.
The motherboard looks identical to the one from the Mercedes. The only difference is the loaded software.

I read on https://v60service.hu that there are cases that after washing the compressor and replacing the dryer, the climate can work. I think I will follow this path, since I did not find any faults in the control unit and compressor windings.

Fingers crossed.
Report the results of the compressor revival operation.

assembled the system. Nothing has changed...

Maybe write to people from v60service.hu if any restart/reset procedure of the ACCM module is required.

You definitely need to clear the error via VIDA.

You may additionally need to reset the ACCM module;
VIDA->SOFTWARE->ADVANCED-> select the ACCM module, then press SEND PROG and SEND RESET.

I wrote to them - they do not answer

Added after 5 [minutes]:

The ACCM error has been reset but not VIDA. Reappears. Officials don't want to reset without replacing with a new compressor

How did you sell the board?

I see that you've dug through the topic thoroughly - respect for the work you put in!!!
Do you have a good communication that flies over CAN when the compressor is turned on?

And one more question - do you know if I will be able to handle this air conditioning with the following interface?




Thank you in advance for your response

Michael

I have some VIDAECM communication with a broken compressor in the V60.
But this is not the same as ACCM ECM communication (here you would need to plug the CAN sniffer under the bus connected to the compressor).
I pinged the ACCM module from merc after CAN, but only single frames appeared in response.

I don't know what you mean by "will VIDA-DICE support air conditioning".

The only thing you can do is read the operating parameters:

>>Global parameters
total distance
MECU supply voltage
In-car temperature
OutdoorTemperature
power mode

and

>>The parameters of the ACCM module itself
Requested status A/C-compressor
A/C-compressor status
Requested speed A/C-compressor
Speed A/C compressor
Requested maximum power consumption A/C-compressor
Maximum power consumption A/C-compressor
Temperature A/C-compressor (inverter)
Input current A/C-compressor
High voltage supply A/C-compressor
high voltage supply
High voltage contactor BECM status

There are no manual activation, testing or "adaptation" options.

@grzelecg Thank you for your answer...

I meant if this version will be able to connect to ACCM and reset the system with the procedure you described:

grzelecg wrote:

VIDA->SOFTWARE->ADVANCED-> select the ACCM module, then press SEND PROG and SEND RESET.

The question is will this version of the interface be suitable for this?

Do you have a wiring diagram for the V60? I care most about the CAN to which the compressor is connected, is it not accidentally outputted to OBD?
I connected the CDIF/3 directly to the compressor, but all I can read are errors, serial number and software version.
It is not possible to read any parameters or "reset" the ACCM module.

As for the registration of communication in the car, I have CANoe from Vector.
I've done it more than once... only this time I don't have a car :(

From the VIDAECM communication it is probably possible to get some scraps of information, so if it would not be a problem for you, please send the logs.

Thank you in advance for any information about the air conditioning system in the V60 hybrid

Regards
Michael

The DICE interface you provided is fine. I have the same.

Procedure:
VIDA->SOFTWARE->ADVANCED-> select the ACCM module, then press SEND PROG and SEND RESET

As the first word indicates, it's a procedure in the VIDA program, I have one too.
This is an old version of the offline version of the software with the option of ordering software from the manufacturer.
Currently, there is a newer version of the interface and software in the online version on the manufacturer's website - of course, paid by subscription.

I have schematics. I have to rummage through them and look for the ACCM connection after CAN and whether it has a connection to OBD.

Send me a private email and I'll send you some logs.

From the VIDA database, I also extracted the password for the proc in ACCM, from what I remember, it is: "0102030405" in hex, so probably normally "12345"

Are you repairing ACCM yourself or someone else? Why are you interested in the topic?

Good morning, Grelec.
I completely disassembled the compressor. I can clearly see the closure between phrases. I will rewind the stator.

Thanks for the info. So it is confirmed that the SP-A2 oil dissolves the insulation of the wires.
