Lost Communication With Steering-Angle Sensor Module

Understand U0136, common causes, and the right FOXWELL scanner to diagnose it.

Steering angle sensor module offline — stability control and lane assist need SAS input.

Vanliga symptom

  • ESC light on
  • Lane keep unavailable
  • Stability control disabled

Typiska orsaker

  • Failed SAS in clock spring
  • CAN wiring in steering column
  • Clock spring damage after airbag service

Vilken scanner behöver du?

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

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer

Vanliga frågor

Can I diagnose U0136 with a basic code reader?
U0136 may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Is it safe to drive with U0136?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
