Frequently Asked Questions
Why would I want to turn off stability control?
Some situations where drivers disable ESC include driving in deep snow or sand where wheel spin is needed for traction, performance driving on a track, or rocking a stuck vehicle back and forth.
Does ESC turn back on after restarting the vehicle?
On most vehicles, yes. Stability control automatically re-enables each time you start the vehicle. You must manually disable it again each time you want it off.
Is the C0238 code a problem?
Not if you intentionally pressed the ESC off button. The code is simply a record that the system was disabled. If the code sets without you pressing the button, the switch or its wiring may be faulty.
