Problems with colorMFA on Seat Leon mk1

[pablobnc]

Hi! Last week I installed colorMFA on a golf 4 dash (1J5 920 826) to be installed on a Seat Leon mk1 fr (ARL 150hp).

When I have it installed I realised that the colorMFA didn't notify me the low level of winshield cleaning liquid, but the original buzzer of the dash beeps (before I have seen on the Leon original dash that I had low level). Later I discovered that colorMFA doesn't notify me when I open any door, what can be the fault? I loaded an eeprom prepared for install the golf iv dash on a leon.

Another doubt I have is about the gear ratios, the leon mounts a FMH gearbox that seems have 2 final drives,and with colorMFA I only can set one final drive, I attach the elsa table:

Check CAN Comfort wiring connection. I think you are wrong. Wires are swapped or connected to wrong points.
See Comfort-CAN data in CAN-Monitor screen (in ColorMFA menu).

Information about recalculation gearbox final drive from 2 to 1 present in manual.
Also present here: GEAR RATIO (Пост evoR32 #5408)

Okay, I will check the CAN-Monitor screen and if I don't see nothing I will open the dash. Thanks for the recalculation info!

Hi, yesterday I checked the CAN Comfort wiring connections and are fine, later I opened the CAN-Monitor and it displayed no data or something similar. To discard options I put the dash on my golf iv and there it seems to work fine, it displayed open doors and on the CAN-Monitor appeared data.
(Dash on my golf iv):


After that I reinstalled the dash on the Leon and I opened the CAN-Monitor and it displayed this, but didn't display open doors or anything:



It's possible that the Leon doesn't have the wiring between the Comfort Module and the dash like 1J0? The Leon CCM is a 1C0

1J0 - old comfort (CCM) for immo2 cars. CAN-bus wires not connected to cluster in original wiring harness.
For this cars need install ColorMFA to immo2 cluster. Need add CAN-bus wires from CCM to cluster. Washer level warning signal must be connected to washer level warning light (from ColorMFA TrInput8). In ColorMFA need use firmware for immo2 cars.
If you install ColorMFA to immo3 cluster for use in this car, need cut traces on original cluster PCB or remove resistors like on photo:

Cluster Comfort-CAN must not be connected to CCM CAN-bus or ColorMFA CAN-bus. Immo2 (1J0) CAN is incompatible with immo3 (1C0) CAN.

1C0 - new CCM for immo3 cars. CAN-bus wires already present to cluster in original wiring harness.
For this cars need install ColorMFA to immo3 cluster. In ColorMFA need use firmware for immo3 cars.

What is the year of manufacture of the Leon ?
1J0 installed to cars up to 04/2001. 1C0 installed from 05/2001.

I'm seen Leon schematic and not found wires from CCM to cluster (1J0 and 1C0 does not have connection to cluster). On cluster pinout is also not present this wires (pins marked as "free").
I think need add CAN-bus wires from CCM to cluster.

[pablobnc]

So it seems its clear, everyhing seems to point that, do you know the CCM pins I have to take to the green conector?

[autopilot]

- from CCM pin6 (orange-brown wire) to cluster pin9 - CAN-Low
- from CCM pin9 (orange-green wire) to cluster pin8 - CAN-High

Okay, next weekend I will try, thank you!
