Cruise Control Front Distance Range Sensor Left
General fault on the left-side front distance-range sensor used by adaptive cruise. Multi-sensor radar arrays use left/center/right sensors for wider field-of-view and lane discrimination — without left, ACC may degrade to single-target tracking.
Affected components
- Acc radar sensor left
Common causes
- High likelihood: Dirty sensor surface
- Medium likelihood: Sensor misaligned after a frontal impact
Diagnostic notes
- The malfunction indicator lamp may illuminate
