Solution

1. Tire Inspection

Check Tread Depth: Use a depth gauge to measure tread depth. Replace tires if tread is below 3/32 inches.
Inspect Sidewalls: Look for cuts, bulges, or other damage. Replace damaged tires.
Verify Tire Type: Ensure tires are designed for wet conditions (e.g., all-season or performance tires).

2. Tire Pressure Adjustment

Check Pressure: Use a tire pressure gauge to measure each tire's pressure.
Inflate Tires: Inflate tires to the recommended PSI found in the owner’s manual or on the driver’s door jamb.
Recheck Pressure: After driving a short distance, recheck the pressure to ensure it remains stable.

3. Traction Control System Check

Scan for Codes: Use an OBD-II scanner to retrieve any error codes related to the traction control system.
Clear Codes: If any codes are present, document and clear them to see if they return.
Inspect Sensors: Visually check wheel speed sensors and wiring for damage or corrosion.

4. ABS Functionality Test

Activate ABS: Conduct a slow-speed stop on a wet surface to ensure the ABS activates as intended.
Listen for Activation: You should hear a pulsing noise if the ABS is functioning correctly.

5. Suspension Inspection

Visual Check: Inspect control arms, bushings, and struts for any signs of wear or damage.
Test Components: Push down on each corner of the vehicle to check for proper shock absorption and rebound.
