Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Remove the wheel corresponding to the faulty sensor indicated by the C0001 code.
3. Disconnect the ABS wheel speed sensor connector.
4. Remove the wheel speed sensor from its mounting location.
5. Install the new wheel speed sensor by reversing the removal steps.
6. Reconnect the ABS connector ensuring a secure fit.

3. Check ABS Module Connections

Sub-steps:
1. Locate the ABS module, typically near the master cylinder.
2. Disconnect the electrical connector from the ABS module.
