why does my Toyota Camry Eighth Generation (2018-present) stability control light stay on

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.
• Allow the vehicle to cool down if it has been running.

2. Scan and Clear Codes

• Use an OBD-II scanner to scan for error codes.
• Note any codes related to the stability control system.
• Clear the codes and check if the light returns.

3. Inspect and Replace Wheel Speed Sensors

• Tools Required: Socket set, multimeter
• Locate the wheel speed sensors on each wheel.
• Disconnect the sensor harness and remove the sensor using a socket.
• Inspect the sensor for damage and check resistance with a multimeter (should be within specifications).
• If faulty, replace with a new sensor and reconnect.

4. Check Brake Fluid Level

• Locate the brake fluid reservoir under the hood.
• Inspect the fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
• If the fluid level is low due to a leak, inspect brake lines and connections.

5. Inspect ABS Module

• Tools Required: Socket set, multimeter
• Locate the ABS module and check for any visible damage or corrosion.
• Inspect the wiring harness for frayed wires or poor connections.
• If necessary, replace the ABS module according to the manufacturer's specifications.

6. Test Stability Control Switch

• Locate the stability control switch on the dashboard.
• Test the switch for proper operation using a multimeter.
• If it is faulty, replace the switch.
