Hello again. Trying to fix this cruise control issue. ECU is 022906032DP me7.1.1, ori cruise control is controlled via HW pins with 4-way buttons on the turn signal stalk. I've had success enabling a 6-way separate CCS stalk via CAN bus by changing CW_GRABH to 3 (set bit 0 and 1) on my previous ME7.5, but this time it doesn't work. When CCS main switch is OFF, there are no errors, but immediately when i turn it ON, it spits out this "Cruise control switch - implausible signal" fault and, obviously, CCS doesn't work. Last two bits of CCS status get set and don't reset until i clear faults. All CCS buttons are being seen correctly by the ecu (master on/off, accel decel etc.).

Any ideas ?

Solved. My fault, wrong HW connection for CCS ON.
