CAN BUS message decoding

Hotter · 04-29-2020, 01:41 AM

Hi, I am trying to understand CAN BUS message from 0x1D0 id, to see interesting information with Arduino. Maybe anyone know what are the meaning of these:

?

So far I know the meaning and formula of these:

Code:

TEMP_EOI        Coolant temperature. (Byte[0] - 45 = temp in C)
TEMP_ENG        Oil temperature. (Byte[1] - 45 = temp in C)
ST_SW_WAUP      ???
ST_RBMCYC       ???
ST_END_RUN      ???
RPM_IDLG_TAR    ???
RDUC_DOCTR_RPM  ???
OPMO_FU         ???
IJV_FU          Amount of fuel injected (Byte[5] * 256 + Byte[4] = in microliter) ???
CTR_SLCK        ???
ALIV_COU_DME    ???
AIP_ENG         Air intake pressure (790 + Byte[3] = in hPa) ???

Hello, here are the meanings of the rest of the signals to my understanding:

Code:

TEMP_EOI        Coolant temperature. (Byte[0] - 48 = temp in C)
TEMP_ENG        Oil temperature. (Byte[1] - 48 = temp in C)
ST_SW_WAUP      1= Warm-up Function active (Heating Catalytic Converters, EGS warmup) (Startbit 22, length 2)
ST_RBMCYC       1= RBM cycle active (Startbit 54, length 2)
ST_ENG_RUN      Status Engine: 1= Engine runs (Startbit 20, length 2)
RPM_IDLG_TAR    Signal to the EGS for the target idle rpm to improve gear change (Startbit 56, length 8 * 5 = rpm)
RDUC_DOCTR_RPM  Notification to the transmission that the engine is in limp-home with lowered max rpm in order to adjust shift rpms (Startbit 52, length 2)
OPMO_FU         Only used in E68 for fuel indicator (Gasoline/Hydrogen) (Startbit 20, length 2)
IJV_FU          Amount of fuel injected (Byte[5] * 256 + Byte[4] = in microliter) 
CTR_SLCK        Inhibits unlock of gear selector lever by the EGS (Startbit 48, length 2)
ALIV_COU_DME    Alive counter. This signal is incremented every 200ms (Startbit 16, length 4)
AIP_ENG         Absolute air pressure (Startbit 24 length 8)*2 + 598 = Absolute air pressure in hPa)

Thanks, great information. Do you know any other similar interesting KCAN BUS messages which would be interesting to see while driving?

Is it possible to calculate Air/Fuel ratio from "absolute air pressure" and "fuel injected"?

Hotter · 05-01-2020, 07:46 AM

Is there can bus message for Oil amount?
Also washer fluid and coolant fluid amount?

Air Fuel Ratio is available as a standard OBD diagnostic. If you have Torque check out DWR's post about custom PIDs.
AFR is on PID 124. Formula is (((A*256)+B)*000031.

The oil amount is available in the CIC if you enable engineer mode per coding. But the oil level is more than flaky. I'm thinking that the oil sensor is not really capable of measuring the amount.
I'm not aware of coolant fluid level. That should be just a switch.

Is that on KCAN hex PID? Because I am reading KCAN network messages. Would be nice to get all list with descriptions of KCAN messages, but I guess such does not exist?

No, that is a KWP2000 diagnostic PID as far as I know. KWP2000 is a diagnostic protocol that can be either transmitted as serial protocol or on CAN.

I have noticed that this "IJV_FU (Amount of fuel injected)" is increasing like a timer and reset when it reaches maximum value:

Does this mean fuel injected is the difference between previous value and the current value?

What an odd signal this is. It says it is the used fuel - a summation of all injected quantities. Values are in uL.

I log similar signal on my N52. Maybe it does not work for N52 engine? But that would not explain why its like "timer".

So far I know the meaning and formula of these:

Code:

TEMP_EOI        Coolant temperature. (Byte[0] - 45 = temp in C)
TEMP_ENG        Oil temperature. (Byte[1] - 45 = temp in C)
ST_SW_WAUP      ???
ST_RBMCYC       ???
ST_END_RUN      ???
RPM_IDLG_TAR    ???
RDUC_DOCTR_RPM  ???
OPMO_FU         ???
IJV_FU          Amount of fuel injected (Byte[5] * 256 + Byte[4] = in microliter) ???
CTR_SLCK        ???
ALIV_COU_DME    ???
AIP_ENG         Air intake pressure (790 + Byte[3] = in hPa) ???

Sorry for reviving this old thread, but what Tool is this?

pherath · 05-27-2023, 07:24 PM

Does anyone know what the Oil Pressure signal is for the N55?

Do you know any other similar interesting KCAN BUS messages which would be interesting to see while driving? Is it possible to calculate Air/Fuel ratio from "absolute air pressure" and "fuel injected"?
