What the C0283 code means

The ABS module (EBCM) controls the anti-lock brakes and, on most modern vehicles, traction control and stability control too. When it detects a fault, it disables those functions and turns on the ABS and stability warning lights. The normal brakes keep working.

The module reads the traction control button. If the signal stays stuck, is impossible or is shorted, it stores the C0283 code and may leave the traction control disabled.

The cause is usually the button itself, liquid spilled in the console, or a loose connector.

Important: many C and B codes are not generic. The definition on this page is the most widespread one, used by General Motors and most generic scan tools, but on other makes the same number can mean something else. Always confirm the code text with a scan tool that reads the right module (ABS, body or airbag).

C0283 code symptoms

  • Traction control warning light on.
  • The traction control does not turn on or does not turn off.

Likely causes of the C0283 code

  1. Failed traction control button. Confirm it with the tests in the diagnosis section.
  2. Liquid spilled in the console. Confirm it with the tests in the diagnosis section.
  3. Connector or wiring. Check the lock, the pins and any moisture or corrosion.

How to diagnose the C0283 code step by step

  1. Read the button state in live data while you press it.
  2. Inspect the button connector.
  3. Measure the continuity of the button.

How to fix the C0283 code

  • Replace the button.
  • Repair the connector or the wiring.
  • Clear the C0283 code and confirm the warning light goes out.

Technical reference data

  • The button is usually a momentary pushbutton to ground.
  • These values are approximate. Check the manufacturer data for your vehicle.

Brand-specific notes

If the console has been wet, dry it and clean the contacts before you buy a new button. Sticky residue from spilled drinks is a common reason for a button to stay stuck.
