my Honda Accord 10th Generation (2018-2022) has traction control issues, what should I check?

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery to prevent electrical shorts while working on the vehicle.
• Ensure the vehicle is on a level surface and use wheel chocks for safety.

2. Inspect and Replace Wheel Speed Sensors

• Tools Required: Socket set, multimeter, torque wrench
• Using a socket set, remove the wheel assembly to access the wheel speed sensors.
• Disconnect the wheel speed sensor wiring harness.
• Use a multimeter to check the resistance of the wheel speed sensor; it should typically be around 1,000 ohms.
• If the sensor is faulty, replace it with a new one, ensuring it is properly seated and connected.
• Reassemble the wheel assembly and torque the lug nuts to the manufacturer’s specifications (typically around 80 lb-ft).

3. Check and Refill Brake Fluid

• Tools Required: Brake fluid, funnel
• Locate the brake fluid reservoir and check the fluid level. If low, clean the area around the reservoir cap to prevent contamination.
• Use a funnel to add the appropriate type of brake fluid (usually DOT 3 or DOT 4) until it reaches the maximum fill line.
• Re-secure the cap tightly.

4. Inspect ABS Module and Wiring

• Tools Required: Visual inspection tools (flashlight), multimeter
• Visually inspect the ABS module and wiring for physical damage or corrosion.
• If any wires are damaged, repair or replace them as necessary.
• If the ABS module is suspected to be faulty, consider testing or replacing it based on manufacturer guidelines.

5. Battery Voltage Test

• Tools Required: Multimeter
• With the vehicle off, use a multimeter to check the battery voltage; it should read around 12.6 volts.
• If the voltage is low, charge or replace the battery before proceeding.
