Coding

 

Change byte 4 from 0B to 49 and byte 12 from D0 to 92.

 

Thank you very much!

Everything else good and no codes, only lights (55) giving me this code:

ill check the long coding again but not sure if thats from my wirework or from something else.

 

there is this coding setting, and as i previosly had 4, and now just 2 (fl and rl).
Does this mean it should be on? Or does it mean something else.

i am unable to test, it says coding out of range

 

I can’t remember which bit or byte, but if you browse through all the coding string, there should be a bit that says “receive info over CAN” or something like that. Uncheck that bit.

 

Yes, byte 1 bit 3, i changed that. When im checking live data, sensor are staying still. Maybe i wired something wrong?

 

Very possible. 3 wires per sensor (5v, ground, signal). Go over your wiring again

 

I just checked my coding, enable byte 2 bit 1. Also, what's your byte 1 coding?

 

This is when i try to turn byte 2 bit 1 on.

and this is byte 1 now:

it was ae because i had bit 2 on for testing.

 

No luck also on wires, all seems to be rightly connected according to alldata oe electrical diagrams.
And tested that they are closed connections.

I think its now to do with the byte 2 bit 1.

 

Fault code databus problem seems to be with light module (under radio) and pin 15. If i remember, there is nothing connected to it, and i believe it shouldnt be looking for any info on it. Could it be trying there because of the byte 2 bit 1 is off

 

The light module under the radio should have things connected to it, that’s where you should have wired your two sensors to.

did you enter a security code when changing coding?

 

Yes it does have and thats where i connected, just the pin 15 i dont remember connecting.

actually no, i didnt put in security code, vcds didnt tell me it. Where can i get it?

 

Pin 15 of the headlight control module J745 shouldn't have anything connected to it.

 

I went over wiring - okay, no problems.
Tried to code (55) byte 2 bit 1 to on with security access, no luck. It is trying to retrieve information from j745 pin 15. This would change if 55-byte 2, bit 1 was on. Anyone have the coding for 09 and 55 with xenons and no air suspension?
