B = Body code

0 = Generic (SAE standard)

How to Fix B00CA

Follow these diagnostic steps to identify and resolve the issue. Always start with the simplest checks before moving to more involved repairs.

  1. Check for objects jammed in the seat track mechanism.
  2. Test the seat control switch — listen for motor relay clicks.
  3. Apply 12V directly to the seat motor to test it independently.
  4. Inspect wiring under the seat for damage, especially from items stored underneath.
  5. Check fuses and circuit breakers for the power seat circuit.
  6. Replace the seat motor or control module as needed.
  7. Clear codes and test all directions of seat movement.

Note: These are general diagnostic guidelines. Some vehicles may have model-specific procedures. Always consult your vehicle's service manual for exact specifications and torque values. If you are not comfortable performing these steps, visit a qualified mechanic.

Frequently Asked Questions

Is B00CA serious?

The severity depends on the underlying cause. Some triggers for B00CA are minor (like a loose gas cap), while others may indicate a more significant problem. We recommend having the code diagnosed with a proper scan tool to determine the exact cause before deciding on urgency.

Can I clear B00CA myself?

You can clear any OBD-II code with a code scanner or by disconnecting the battery for 15-30 minutes. However, clearing the code without fixing the underlying problem will cause it to return — usually within one or two drive cycles. If the code triggered the check engine light, the light will come back on. Fix the root cause first, then clear the code.

How much does it cost to fix B00CA?

Repair costs vary widely depending on the root cause. Some fixes are free (like tightening a gas cap) while others can cost several hundred dollars (like replacing a catalytic converter or oxygen sensor). A proper diagnosis with a professional scan tool — not just reading the code — is the first step to getting an accurate repair estimate. Many auto parts stores offer free code reading, but a thorough diagnosis usually requires a mechanic.
