Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during the repair.

2. Inspect and Repair Wheel Speed Sensors

Tools Required: Socket set, multimeter, wire brush, dielectric grease.
Inspect each wheel speed sensor:
- Remove the wheel to gain access to the wheel speed sensor.
- Clean the sensor and mounting area with a wire brush.
- Apply dielectric grease to the connector to prevent corrosion.
Check sensor wiring:
- Inspect the wiring for frays or cuts.
- Repair any damaged wiring with electrical tape or replace if necessary.

3. Test and Replace ABS Control Module (if necessary)

Tools Required: Socket set, OBD-II scanner.
If the wheel speed sensors are functional, test the ABS control module:
- Reconnect the battery and use the OBD-II scanner to monitor ABS module status.
- If the module shows faults, replace it according to the following steps:
  - Disconnect the battery.
  - Remove the module mounting bolts and disconnect the wiring harness.
  - Install the new ABS control module by reversing the removal steps and ensure all connections are secure.

4. Clear Codes and Test Drive

Tools Required: OBD-II scanner.
Use the scanner to clear the C1000 code from the vehicle's computer.
Test drive the vehicle to ensure that the Check Engine light and ABS warning light do not reappear.
