Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely parked.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Check and Replace ABS Sensors

Sub-steps:
1. Locate the ABS sensors at each wheel hub.
2. Disconnect the wiring harness from the sensors.
3. Remove the bolts securing the sensors using a socket set.
4. Inspect the sensors for physical damage; replace if necessary.
5. Install new ABS sensors by reversing the removal steps and torque bolts to manufacturer specifications.

3. Inspect VSA Module Wiring

Sub-steps:
1. Locate the VSA module, typically found under the dashboard or in the engine compartment.
