Skoda Rapid BCM Max Adaptation. 6R093708P upgrade 7h0937090d BUT!

[omerkartal]

Hello friend, there is no lamp other than the original. If you want, you can share the BCM max coding now.

[ciclo]

Taking as a reference the BCM 087 coding of the autoscan hosted on Google Drive, you can use this provisional BCM coding for testing and know what needs to be corrected.

BCM Max coding:
7A980B2000C32C00010806B07ECB1EC00E80600F608E2041020000024000

New report.
-Visual inspection of the operation of the lights, remember that they must be activated so that the faults can be observed in the autoscan (R Fog, reverse, plate lights, etc.).
-New autoscan.

Hello friend Ciclo, the headlight sensor and rain worked with the BCM max coding you sent a short while ago. The daytime running lights are on even if the ignition is off when the headlight switch is in position 0. The second problem is that the signals are not reflected on the display screen. I added the video and the BCM auto scan logs to Google Drive. Thanks to you, we have made great progress. I am looking into the logs and waiting for your return.

Have you installed WL1? I'm afraid not. These are the new CAN communication lines between the instrument panel and the BCM Max. It is mandatory.
For your information, they are present in the BCM Max Adaptation guides I made.



Do exactly the same as the picture above. It is important to individually isolate the wires of the CAN lines that you remove on the instrument panel, it is the powertrain CAN line that is still live for other units.

Yes, I missed that. You showed your genius again We took a break until Tuesday. We'll try it on Tuesday.

probably the daytime running lights are still connected in the old way. bcm is not connected either. we will check that on tuesday.

[ciclo]

I guess being the Creator and source of information on all this PQ25 automatic lights, etc, etc, etc... and many years of experience allow me to identify any problem at a glance, there is no genius in this.
I appreciate your comments/praise towards me, although they are not necessary. I am more pleased to know the enthusiasm, interest and will that you are putting into this.

As described in the BCM Max adaptation a new wiring harness for the DRLs must be installed. The old/factory DRL wiring harness which goes through the SB17 (7.5A) fuse must not be connected to the new auto lights wiring harness with the new T10 connector for the new AUTO light switch as it could be damaged.

DRLs with BCM Max and with 'Auto lights' must be under BCM control to function correctly at all times.

Good morning Fernando. I noticed it yesterday when I stopped by the car. When I want to turn the high beams on steadily, they don't come on. When I pull the signal lever forward, it stays on for a long time, when I let it go, it goes off. When I push it back, it doesn't stay on steadily.

Good morning, omerkartal.

You must first clarify what is the status of the wiring installation for the BCM Max Adaptation... Please post an autoscan every time you want to know what is happening, or if you find faults or malfunctions.

The new wires for BCM Max 090 are useless if you temporarily install the factory BCM High 087 because for example you did not finish the installation.
Once the electrical installation for BCM Max adaptation has been completed, the BCM Max must be installed, any other circumstance/status is meaningless.

Hello Fernando, which pin do we connect to the BCM Max for the DRL lamp?

[ciclo]

According to the installation guide I altruistically made:

---


DRL (TFL).

- Remove/isolate original T17/3.
- New wire 0.5mm2 from new T10/9 connector to T73b/29.
- New wire 0.5mm2 from T73b/3 to T10a/4 of left headlight connector. Remove/Isolate original T10a/4.
- New wire 0.5mm2 from T73a/5 to T10b/4 of right headlight connector. Remove/Isolate original T10b/4.

Try to do the diagnostic sessions with a power source feeding the Battery... or at least do the Autoscan and clear the faults with the vehicle started.

New GW coding (with BCM Max installed).

Following the installation guides usually gives good results...

Hello again Fernando
All the operations in the car are finished today.
I just took a video as a problem I observed. When I want to turn the high lights on constantly, it does not react and does not give an error. I uploaded the Auto Scan scan and the video to Googledrive.

Thank you very much for your support so far.

[ciclo]

Do the following and upload the log to google drive so that I can see it.
https://drive.google.com/drive/folders/ ... sp=sharing

Do a new Autoscan with the following new BCM coding.
7A980B2000C32C00010807B07ECB1EC00F80600F608E2041020000004000
With this new BCM coding you must check the operation of the high beams with all positions of the light switch and engine on.
Upload the new Autoscan to google drive without clear the DTCs/faults.

Pending the results above, I'm afraid that something is wrong with the Headlights Relay in the automatic lights wiring you've made, either the relay itself or with one of the 4 wires that go to the relay adapter.
It's also possible that there are problems with the new wire you spliced to fuse 36a that goes to T73a/62 (fuse 36 is logically fine).
These are just guesses, let's wait to see the logs to continue...

I will do as you said tomorrow. I noticed it when I got out of the car in the evening. Coming Home is on but it doesn't work, but Leaving Home works.

[ciclo]

Coming Home function is semi-automatic on the PQ25:
Light switch in AUTO position, ignition switch OFF, pull the HB flash lever once, open the driver's door, and the lights will come on.
