VCS light on dash. VCS is the only light on. Code C1234 won’t clear. Already tried replacing ECU skid control.

ABS light came on once when going through drive through. Car was in drive, foot on brake, ABS came on very briefly, has never come back on.

Hi,

The code is related to the YAW rate sensor. The sensor is located under the rear seat. Since the ECU was replaced, chances are it the sensor I mentioned is either bad or the wiring to it has a weak connection.

I attached the directions for checking it. Additionally, the last two pics are the directions for replacing it.

Let me know what you find.

Take care,

Joe
