C0562 — ABS Disabled by Control Module

Severity: medium Drive with care, to a shop

What C0562 means

C0562 means the ABS control module has turned off the antilock function, either on purpose or because it detected a fault. Normally the module watches wheel speed sensors and, when a wheel starts to lock, releases brake pressure through the hydraulic unit. This code often acts as a summary status and appears alongside other C-codes that point to the real cause.

Symptoms

  • ABS warning light on
  • Longer stopping distance in a panic stop
  • Wheels locking under hard braking
  • Traction or stability control light often on too
  • Other C-codes stored at the same time

Possible causes

  1. Faulty wheel speed sensor or its wiring
  2. Failed ABS pump or hydraulic unit
  3. Low system voltage or a weak battery
  4. Module detected unsafe ABS operation and shut it down
  5. Corroded connectors, damaged harness or poor ground
  6. Damaged or dirty tone ring or hub encoder
  7. Internal ABS module failure

How to diagnose

  1. Scan all modules and address any other C-codes first
  2. Test battery voltage and charging output, and check terminals and grounds
  3. Check the fuses and relays for the ABS module and pump
  4. Compare all four wheel speeds in live data on a test drive
  5. Inspect wheel speed sensors, wiring and connectors for damage, dirt and corrosion
  6. Inspect tone rings for cracks, rust and correct air gap
  7. Check brake fluid level
  8. Clear the code and see if it returns after a drive

Common fixes

  • Replace the faulty wheel speed sensor or repair its wiring
  • Charge or replace the battery and fix any charging problem
  • Clean or replace connectors and restore the ground
  • Replace the tone ring or the hub bearing with built-in encoder
  • Repair or replace the ABS hydraulic unit or module

Questions and answers

Can I drive with a C0562 code?

Yes, but carefully and not far. Normal brakes work, but ABS does not. Leave extra following distance and avoid hard braking, especially on slippery roads.

Why does C0562 show up with other codes?

It is a summary status. The module turned ABS off because of another fault, such as a wheel speed sensor or low voltage. Fix that root cause.

Can I just clear C0562?

You can, but if the cause is still there the code will come back. Find the related codes first and repair the underlying fault.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
