Check that the pins of the new CAN lines are correctly inserted in the connectors.
Check that the pins are not damaged.
Check that the two wires are not damaged at any point.

Use a multimeter.

Most of the faults diagnosed on the Autoscan are due to a lack of communication with the IC (J285).

If these CAN line wires were installed for the BCM 7H0 on the Ibiza FR they should work on your Ibiza 6J1.

The wiring harnesses with fuse box, etc., that you have shown in the image come from the same Ibiza as the BCM 7H0?

Yes, the cyclo bundle of cables with fuses is from Ibiza every 7H0937090, I'm going to check the passage on the wires with the meter, I'm not sure if the good connectors are fastened on the cables because the electrician was not sure about the connectors

There is a possibility that the electrician has installed the CAN lines in the BLACK connector of the BCM, when it should be in the WHITE connector of the BCM.

T73b/54 = B connector (white)
T73b/57 = B connector (white)

Cyclo, I put the cables to the bcm / IC, for sure to B / white, I will remove the connectors and put on new ones on Friday and check again, tomorrow around 12 I will post a post regarding the electrical transition

Okay. I know you made some changes to the light switch wires. On the other hand, when we are able to get your BCM Max working properly, I will show you some diagrams from the Ibiza 6P headlights, since the BCM Max PQ25 can and should manage the 6P headlight DRLs.


I am updating the post with the steps that you must follow scrupulously so that it is later available to anyone who reads this thread.

Ajjj Cyclo Cyclo, MQS 000979009E connectors do not match , I have to order 000979009 I will get the package on Tuesday and I will be working immediately and I will throw info on 31.08

Either of the two references you indicate is appropriate for MQS terminals.

Here is a link that will be very useful for you. viewtopic.php?p=466570#p466570

Remember, before working with wires in the car, disconnect the negative terminal of the battery.
I repeat it again, before working with wires in the car, .......... ... ........ ........ .. ... ........

I bought the cables immediately crimped, my crimping tool tightens the insulation badly and does not fit into the T73 ankle, on Tuesday I will be posting info
