5. Installation Instructions

Safety First: Always disconnect the vehicle's battery before performing any electrical work. Ensure the vehicle is securely supported on jack stands. If you are unsure about any step, consult a qualified mechanic.

1. Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and block the wheels. Raise the vehicle and support it with jack stands.
2. Locate the Old Sensor: Identify the existing ABS wheel speed sensor on the rear left or right axle, typically near the brake rotor or wheel hub.
3. Disconnect Electrical Connector: Carefully disconnect the electrical connector from the old sensor. Observe the locking tab mechanism.

5. Remove Old Sensor: Gently pull the old sensor out of its mounting bore. It may require some wiggling due to dirt or corrosion.
6. Clean Mounting Area: Clean the sensor mounting bore and surrounding area to ensure a proper fit for the new sensor.
7. Install New Sensor: Insert the new DNA MOTORING OEM-SS-012 sensor into the mounting bore. Ensure it seats correctly.

8. Secure Mounting Bolt: Reinstall and tighten the mounting bolt to the manufacturer's specified torque. Do not overtighten.
9. Connect Electrical Connector: Connect the new sensor's electrical connector, ensuring it clicks securely into place.
10. Route Wiring: Route the sensor wiring along the original path, securing it with any clips or ties to prevent contact with moving parts.
11. Test System: Reconnect the vehicle's battery. Start the engine and check for any ABS warning lights. Drive the vehicle briefly to allow the system to self-test. If the ABS light remains on, refer to the Troubleshooting section.

6. Operation

Once correctly installed, the DNA MOTORING OEM-SS-012 ABS Wheel Speed Sensor continuously monitors the rotational speed of the wheel. This data is transmitted to the ABS control module. During braking, if the module detects a wheel locking up, it rapidly modulates brake pressure to prevent skidding, maintaining steering control. The sensor operates automatically and requires no user intervention during normal driving.

7. Maintenance

The ABS wheel speed sensor is generally a maintenance-free component. However, periodic inspection during routine vehicle service is recommended:

• Visual Inspection: Check the sensor and its wiring for any signs of physical damage, corrosion, or loose connections.
• Cleaning: If accessible, gently clean any accumulated dirt or debris from the sensor head, ensuring not to damage the sensor.
• Wiring Integrity: Ensure the wiring harness is securely routed and free from chafing or cuts.

8. Troubleshooting

If you experience issues after installing the ABS wheel speed sensor, consider the following:

• ABS Warning Light Remains On:
  • Check Connections: Ensure all electrical connectors are fully seated and secure.
  • Inspect Wiring: Verify that the sensor wiring is not damaged, pinched, or improperly routed.
  • Scan for Codes: Use an OBD-II scanner to retrieve diagnostic trouble codes (DTCs) from the ABS system. This can pinpoint the exact issue. Common codes related to wheel speed sensors include C0031-C0035 (for specific wheel sensor faults).
  • Sensor Installation: Confirm the sensor is correctly seated in its bore and the mounting bolt is tightened.
• Incorrect Speed Readings: While rare, if speed readings are erratic, re-check the sensor's seating and wiring. Ensure the sensor head is not obstructed by debris.
• Intermittent ABS Activation: This could indicate an intermittent signal loss. Inspect connections and wiring thoroughly.

If troubleshooting steps do not resolve the issue, professional diagnosis by a qualified mechanic is recommended.
