Daewoo Car ABS Light On with Fault Code 4040: What Does It Mean?

Model: daewoo Fault Code: P4040 Posted: 2014-09-19 12:36

My Daewoo vehicle shows a persistent ABS light and diagnostic testing reveals fault code 4040. Can anyone explain what this error code means and how to resolve it? I'm looking for specific guidance on troubleshooting the issue related to the anti-lock braking system.

Could you please provide your Daewoo model, year, and engine size for more accurate diagnosis?

I have a 2001 Daewoo Lanos with a 1.4-liter engine. The ABS light has been on for several weeks.

Double-check the fault code — it's possible you may be confusing P0440 (Evaporative Emission System Large Leak) with code 4040. Code 4040 is typically associated with ABS system issues, but confirm the exact diagnostic reading from your OBD2 scanner.
