Try disconnecting the battery for 5 min.

[ahgurbuz]

we disconnected the battery about 7, 8 min. It is same, not solved. I've done a lot of work reading and writing to the EEPROM from this srs ecu, and they didn't have this problem. any advice? best regards

[smart-prog]

And how did you conclude that the problem is in the SRS? Maybe you have a full diagnostics of the car?

[ahgurbuz]

The customer said that the mileage display started flashing after the work done on the airbag control unit. ok, i will do full dagnostics. And also i will do from the same srs ecu tomorrow.I will inform you about the developments.

I would be very grateful if you could also respond to my posts on this topic( Ford Focus-4 2021 PV4T-14B321-AB - CarProTool ). I really need help with that, but I haven't received a reply yet. best regards

hello again,
I deleted the collision record from the same ecu again, and there were no problems. I spoke to the customer again; they're probably misremembering. The odometer should have been flashing before. They had previously changed the radio, which is probably why the odometer is flashing. It should be fixed if proxy alignment is done via the BCM module with a diagnostic tool. best regards
