tft retrofit
Hi guys, I'm new to the forum, I'm like a bmw enthusiast in general.
My hobby is retrofitting bmw cars.
I'm studying for the retrofit of the TFT display on my R1200GS LC of 12/2013. I seem to have found the right thread about this retrofit.
IMHO the retrofit is feasible as long as the TFT cluster is new.
Consulting the wiring diagrams I can see that the analog cluster has an 8-pin connector while the TFT cluster is a 12-pin. as has already been pointed out in your previous posts. The analogue cluster of the 8 pins present uses only 7 of them, while the TFT cluster exploits all 12 pins.
The 5 pins found on the TFT connector are nothing more than an ethernet communication.
These are the pins on the analog cluster
PIN 1 (?) = 30F1 (supply)
PIN 1 (?) = WL_S
PIN 2 = CAN_H (canbus high)
PIN 3 = CAN_L (canbus low)
PIN 4 = 31 (ground)
PIN 5 = empty?
PIN 6 = KS_LIN (Lin bus)
PIN 7 = SZ_LIN (Lin bus)
PIN 8 = empty?
As you can see from the following wiring diagram, an error is certainly present. There are two pins 1 ... one of these two pins1 is pin 5 or pin 8. This is not a problem because it occurs once the analog cluster is unmounted.
Here is the wiring diagram of the analog cluster.
These are the pins on the TFT cluster
PIN 1 = 30F1 (supply)
PIN 2 = CAN_H (canbus high)
PIN 3 = CAN_L (canbus low)
PIN 4 = 31 (ground)
PIN 5 = K_RX - (ethernet reception minus)
PIN 6 = K_RX + (ethernet reception plus)
PIN 7 = WL_S
PIN 8 = KS_LIN (Lin bus)
PIN 9 = SZ_LIN (Lin bus)
PIN 10 = K_ACTIV (ethernet activation)
PIN 11 = K_TX - (ethernet tranmission minus)
PIN 12 = K_TX + (ethernet tranmission plus)
here is the TFT cluster scheme:
I noticed that the 5 ethernet cables, from the TFT cluster, go directly to the 16-pole OBD socket (the same as the one used on 8 + 8 pin cars on two rows) which is present on R1200GS LC bikes from 2017.
I think that for the older bikes of 2017 the diagnostic socket is all the classic 10-pin rounds.
In my round 10 pins come 4 cables, of which 2 are for the low and high canbus and the other two are for power and ground.
Any help and ideas are greatly appreciated.
Excuse me for the bad English.
