  • Traction/stability control disabled
  • False activation of ABS
  • Speedometer erratic on some models

Causas típicas

  • Failed right rear wheel speed sensor
  • Damaged tone ring or exciter ring
  • Wiring in wheel well harness
  • Corrosion at sensor connector

¿Qué escáner necesita?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Use datos en vivo y freeze frame antes de cambiar piezas. Códigos ABS, SRS y U suelen requerir un escáner de todos los sistemas.

Consejos de diagnóstico

  • Registre el freeze frame cuando se active el código
  • Borre el código solo tras corregir la causa
  • Revise códigos pendientes relacionados
  • Verifique que la batería esté por encima de 12,4 V antes de sospechar sensores
