2016 C450 engine code:B23AC64???
Parking Brake (P) light stays on and "BRAKE" light flashes on/off. Hooked up to ECU and code "B23AC64" comes up. Says "electronic parking brake switch implausible signal."
Any help would be appreciated....is this the switch itself or the sensor?? We were able to manually engage the Parking brake through the ecu so its working,

Since your car is still under warranty, I'd take it to the dealer.

Good Luck!

Sorry for bumping old thread. But I have the same fault on mine. Did you get to the bottom with this issue?
