Dash Christmas tree

good afternoon people.

Has anyone had this situation on the 430, my dashboard is with the injection lights, susoensao and transmission on the dashboard. checking with the scanner there are several CAN network malfunctions, I have already checked the grounds and fuses, but without success.
does anyone have any tips?

 

What is the battery voltage at?

 

If you clear the codes, do they come back ? Whats volts are you measuring when the starter engages- low volts can trigger codes if battery on way out. Clear the codes and see if they come back

 

I change

 

11 volts in starter, after clear dtc, is back again

 

Do you have a trickle charger to hook up to the battery? Could clear codes and check again with higher voltage.

 

Does the engine actually start and run? I can't open your "heic" video files.

What was the car doing before this happened? Was it in storage for a while? On the road? Being serviced?

Did you check the maxi fuses near the battery?

 

11 volts on system with starter engaged is fine, your codes coming up again is another issue

Yes. Don't work

 

Yes too, all r/l, next battery and the front

 

Today I will check the ecu airbag. Because I read the CAN it's problem and I check my scanner don't take this ecu.

I try change the scanner and see the uc airbag is ok.

Does this mean you changed the battery and reading 11 volts? Or just under load when starting?

 

Just under load when starting. Afeter that 14.2V.

 

Translation for post #14

P0410 clutch sensor
P0420 selection sensor
P0440 engagement sensor
P0940 "shift switch lock" ?
P1701 left rear wheel speed (vehicle speed)
P1704 engine speed (tacho).

There are no common power sources for these items.
Vehicle speed comes from the Suspension ECU. The suspension provides speed data to other computers via the C CAN Bus.
Engine speed comes from the RH Engine ECU (usually). Speed data is provided to other computers and to the instrument panel on the C CAN Bus.
The gearbox sensors are powered directly the F1 TCU. The TCU communicates with other computers via the C CAN Bus.
The C CAN Bus has green and white wires.

All of these computers are connected to the OBD2 port via the CAN Bus and the older B CAN Bus, but I don't know which bus the OBD2 port normally uses.

As the engine is running, then, I assume, there is nothing wrong with the engine speed sensor. Are you getting tacho (rpm) information on your instrument cluster?

Was the engine turned off when you did your scan with the second scanner?

 

Hi, my tacho don't work.
I change the scanner. This read the airbag, but the others unit it's the same dtc.

I see this unit e-diff have can bus and I disconnect for test my dtcs it's sames too, today I open for check and try change another f430 I have for a test

Hmmm... not much will work on the car without engine speed information. Again this is related to the C CAN Bus. All I can suggest is check the CAN Bus wiring from the RH Engine ECU to things like the instrument panel, the OBD2 port, etc.

I try to check the wiring. Ths for the diagran. In the workshop manual don't have all diagrans.

 

Hi mate, why use the picture of my obd2 read codes? There is no problem to use, its just to know becausemy car is a 360 and this one is a 430!! because i have my post about the issue and yesterday i refresh the information. Dont know if this car have the same problem of mine, but its interesting to know and share possible solutions!

Cheers

 

Because your photos are *heic files and the photo is not visible on all computers. I had to download an image file converter for my PC.

That particular photo shows:

P1704 engine speed (tacho).

 

After to hard fight this 430 and help my friend Qavion. The problem is fix.

My cluster have a problem in can bus, after a change is gone.

Ths all for help me
