Solution

1. Preparation

Gather all necessary tools and equipment.
Disconnect the negative battery terminal to ensure safety.
Raise the vehicle and securely support it on jack stands.

2. Inspect the Left Rear Wheel Speed Sensor

Tools Required: Socket set, multimeter
Remove the left rear wheel to access the wheel speed sensor.
Inspect the sensor for any physical damage or debris that could obstruct its function.
Check the wiring harness for frays or disconnections. Repair or replace any damaged wiring.

3. Test the Wheel Speed Sensor

Tools Required: Multimeter
With the multimeter set to the resistance setting, disconnect the sensor's electrical connector.
Measure the resistance across the sensor terminals. The typical reading should be between 1,000 to 2,500 ohms. If the reading is outside this range, replace the sensor.

4. Check ABS Module Connections

Ensure that the ABS control module connectors are secure and free from corrosion.
Clean the connectors with electrical contact cleaner if needed.

5. Reassemble and Reconnect Battery

Reinstall the left rear wheel and lower the vehicle.
Reconnect the negative battery terminal.

6. Clear Error Codes and Test

Use the OBD-II scanner to clear any existing codes.
Take the vehicle for a test drive, monitoring for the reappearance of the C1232 code.
