BMW fault code 65B7
Active cruise control
LDM interface (yaw rate) signal implausible
Module version: Active cruise control (FRR_70)
Reading and clearing it
Fault code 65B7 is a BMW code, stored in the car's active cruise control, not a generic OBD2 code (P0xxx): a generic OBD2 reader only reaches the engine's emissions faults, so it won't show it. AutoLingo for BMW reads it with BMW's own diagnostic protocols, in plain English, with the details the module stored about it, and clears it after a repair. If a fault comes right back after it's cleared, the problem is still there.
The active cruise control is on: 5 Series (E60), 5 Series (E61), 6 Series (E63), 6 Series (E64), 7 Series (E65), 7 Series (E66), 7 Series (E67), X5 (E70), X6 (E71), X6 (E72), Z4 (E85), 1 Series (E87), Z4 (E89), 3 Series (E90), 3 Series (E91), 3 Series (E92), 3 Series (E93)
