Surprises after installation.



1. Connected Multiecuscan went to body computer and to read errors:
U1711 - Automatic Transmission (NCA-NCR)
U1706 - Brake system (NFR)
U1702 - Electric Steering (NGE)
U1701 - Engine control (NCM)
U0001 - C-CAN
U0426 – Minicrypt
U1726 - Airbag Node (NAB)
Plus Christmas tree lights all on.

I tried to clear the fault codes but they all came back on. OK, I thought I have damaged the car big time. It was around 21H so I left the car and thought, ok tomorrow is another day. Next morning I remembered I had forgotten to connect the earth cable under the ABS unit. Connected it but still had errors. More trouble shooting. Decided to re check wiring, Bingo! Found the problem. I had told my dad to solder the wrong can bus wires.

He soldered the CAN HI from the ABS to the Can Lo going to the Yaw sensor and Can Lo to Can Hi. Corrected the wires and I was able to do proxy alignment.

I still had many error codes. I took over 3 weeks to be able to clear them all out.


Gearbox Dualogic CFC300

1: P290F - Side Acceler./Yaw Node (NYL)
The longitudinal acceleration signal learn operation must be performed
Longitudinal acceleration signal learn

I took a long time to figure what this error was until I found training manual on the internet for the Ducato M40 Dualogic gearbox with the following:

Yaw sensor learning
The procedure follows the guidelines shown below:

Cases in which it should be carried out:

- Replacing the gearbox control unit
- Replacing longitudinal acceleration sensor (NYR)

Reasons why it should be carried out:

The following procedure is used to learn the longitudinal acceleration set-off value transmitted by
the NYR.

Failure to execute the procedure impairs system operation. This procedure must therefore be run
at the end of line and in service.

The problem was that in Multiecuscan for the 1.3MTJ CFC300 gearbox there is no procedure for the “longitudinal acceleration sensor learn” I tiered to select the 1.4 engine which uses the CFC328 and it has this procedure. I got a wrong ISO code but continued and it worked. (Later found out Alfaobd has this procedure for the CFC300)

2: P0856 - VDC messages (from CAN)



ABS ECU
C0051 - Steering angle sensor (NGE)
Disappeared once I fitted the new steering column with position sensor.

C1213 - System configuration
Incorrect control unit or calibrations

This was the most stubborn error to solve. I tried to do an engine reset with Multiecuscan but that did nothing. I assumed that the incorrect control unit or calibration had to do a steering angle calibration in the ABS computer. And change the configuration in the body computer form ABS to VDC.

The big problem was that Multiecnscan does not have these options for the Grande Punto. I then found out that Alfaodb has them. However when I tried to do the steering angle calibration in AlfaODB it said conditions not correct. I decided to email Alfaobd support.

I can say that it has the best customer support I have seen. Alexey emailed me and said for me to try the lasted version which has Car Configuration, where you can change the body computer from ABS TO ESC. When I tried it crashed and lost connection. Alexey then asked me to send a debug file. He then sent me a beta version of the program corrected for my problem. I was then finally able to change the body configuration. Once this was done a proxy alignment and no more errors.

I now have ESP, ASR and best of all Hill holder which for the dualogic is the best thing.

Alterations that need to be do with diagnostic software.

Body computer
Change from ABS to ESC/VDC/ESP


Abs
The longitudinal acceleration signal calibration

If you have dualogic Gearbox
longitudinal acceleration sensor learn

I also reset the Engine ECU

The ABS steering angle calibration was not necessary.

It was also not necessary to change the Hill holder assist value AlfaOBD car configuration.
