⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems to prevent shorts or shocks.
•Work in a well-ventilated area when using cleaning solutions.

Symptoms

•Warning lights illuminated on the dashboard related to the collision avoidance system
•Audible alerts or beeping sound when no obstacles are present
•Inconsistent or delayed activation of braking when approaching an obstacle
•Malfunction indicator lamp (MIL) illuminated
•System failure message displayed on the infotainment screen

Diagnostic Steps

1
Scan the vehicle's onboard diagnostics (OBD-II) for any error codes related to the collision avoidance system.
2
Inspect the sensors (front, rear, and side) for any physical damage, dirt, or obstructions.
3
Check the wiring and connections leading to the collision avoidance system for corrosion or loose connections.
4
Ensure that the vehicle's battery is fully charged and connections are secure, as low voltage can affect system performance.
5
Perform a visual inspection of the vehicle's camera systems, if applicable, for cleanliness and proper alignment.
6
Test the operation of the collision avoidance system using a diagnostic tool to simulate conditions and observe system responses.

Solution
