What changes
Module 09: object 0D1D, byte 0, bit 0 = 1. When reverse is engaged the front fog lights come on.
Details
Lights up the area in front of the car while reversing — with the fog lights. Only with front fog lights. Object 0D1D exists on both module generations with a different layout (bit 0 on the module without coding, bit 1 on the coded module) — Odyx checks that long coding 09 is empty and refuses otherwise before writing. The bit is not yet confirmed by a write on a Q3 F3. Access code 31347; the module accepts changes only with the bonnet open. Rollback: write the object backup from the history.
