P2583

What it means

General fault on the radar/lidar/camera distance-range sensor used by adaptive cruise control. On systems with a single sensor or three sensors with a center unit, this code refers to the central sensor — without it, ACC distance control is disabled and the system falls back to plain cruise.

Is it safe to drive?

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.

Most likely causes

• Dirty sensor surface (radar emblem / camera lens)

  high

  One of the most commonly reported causes for this code — check this first.

• Sensor misaligned after a frontal impact

  medium

  A plausible cause — test and verify before replacing parts.

• Failed sensor module

  low

  Less common, but worth ruling out after the more likely causes.
