B109171 symptoms

A diagnostic code identifies a detected condition; it does not by itself prove which component has failed. Symptoms can differ between vehicles. Record the exact warning message, any additional codes, and the operating condition when B109171 appeared.

Possible causes of B109171

Possible causes depend on the vehicle-specific definition and test results. Do not conclude that a named component has failed from B109171 alone; wiring, connections, control conditions and component tests should be evaluated using manufacturer procedures.

  2. Confirm the vehicle make, model, model year and powertrain before applying a reference definition.
  3. Prefer a verified manufacturer-specific report when one is available.
  4. Follow the manufacturer diagnostic procedure before replacing parts.

How to fix B109171
