2015-2023 Acura TLX Forward Camera: ADAS Errors, Calibration, and Part Number Matching

Symptoms of a Failing Acura TLX Camera

When the forward-facing camera on an Acura TLX begins to fail, it typically won't cause the car to stop running, but it will disable important safety features. The symptoms are almost always electronic and will appear on your dashboard.

• Dashboard Warning Lights: The most common symptom is the illumination of multiple warning lights on the instrument panel. You may see messages like "Collision Mitigation Braking System Problem," "Lane Keeping Assist System Problem," or "Adaptive Cruise Control (ACC) Problem." These messages indicate that the systems relying on the camera have been disabled due to faulty or nonexistent data.
• ADAS Features Stop Working: Functionally, you'll notice that features like Lane Keeping Assist (LKAS) no longer provide steering input, and Adaptive Cruise Control (ACC) will not maintain distance from the car ahead. The car may revert to standard cruise control, or the feature may be entirely unavailable.
• False or Erratic Alerts: A misaligned or failing camera can cause the system to generate false warnings. For example, the Collision Mitigation Braking System (CMBS) might flash a "BRAKE" warning for no reason, or the Lane Departure Warning might vibrate the steering wheel even when you are centered in the lane. In some cases, this can even lead to phantom braking, where the car brakes unexpectedly.
• Inability to Activate Systems: You may find that you are unable to turn on the LKAS or ACC systems using the steering wheel controls. The system may show an error message immediately upon trying to activate it.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While there are no widespread recalls specifically for the forward camera itself on the 2015-2023 Acura TLX, the ADAS system it belongs to is complex and has been the subject of service bulletins.

• NHTSA Recalls: As of early 2026, searches of the National Highway Traffic Safety Administration (NHTSA) database do not show any recalls directly targeting the forward-facing camera for failure. However, other recalls exist for the TLX, so it is always wise to check your specific VIN.
• TSB 15-027: Acura released this Technical Service Bulletin for 2015-2016 TLX models (among other Acuras) addressing a symptom where the "LKAS Does Not Keep Vehicle in Detected Lane." The bulletin notes that the cause can be an improperly secured wiring harness for the camera unit, which allows the camera to shift out of its correct position. The fix involves properly securing the harness and performing the static and dynamic camera aiming procedure.

Buying a Used Acura TLX Camera: What to Check

Purchasing a used OEM camera is a cost-effective way to restore your TLX's safety features. However, due to the electronic complexity and variations between trims, careful selection is critical.

1. Match the Part Number EXACTLY

This is the most important rule. Acura used many different cameras across the TLX model years and trim levels (Base, Tech, A-Spec, Advance). The part number is specific to the features your car has. Using the wrong camera will result in it not working, even after calibration.

• Locate the part number on your original camera. It will be printed on a sticker on the housing.
• Provide the seller with your vehicle's VIN to help them cross-reference and confirm fitment.
• Do not purchase a camera based only on the model year and vehicle name. A camera from a 2018 TLX with the Advance package may not work on a 2018 TLX with the Technology package.

2. Physical Inspection

Before purchasing, inspect the used camera for any signs of damage:

• Lens: Check for any scratches, chips, or haziness on the lens itself.
• Housing: Look for cracks or damage to the plastic body, especially around the mounting points.
• Connector: Ensure the electrical connector and its pins are clean, straight, and free of corrosion.

3. Why Used OEM is a Smart Choice

For a complex electronic component like an ADAS camera, a used original equipment (OEM) part is often a better choice than a new aftermarket one. The OEM part was designed and tested by Acura to integrate seamlessly with the vehicle's software. Aftermarket electronics can sometimes have compatibility or quality control issues. A used OEM camera, when correctly matched and calibrated, will function exactly as the original did.

Replacement and Calibration

The replacement process for the TLX forward camera is a two-stage job: physical installation and electronic calibration.

Physical Installation (Difficulty: 1/5)

Swapping the camera unit itself is relatively simple.

1. Disconnect the vehicle's battery.
2. Carefully remove the plastic covers behind the rearview mirror.
3. Disconnect the electrical connector from the camera.
4. Gently unclip the camera from its mounting bracket on the windshield.
5. Clip the replacement camera into the bracket, reconnect the electrical harness, and reinstall the covers.

Electronic Calibration (Professional Job)

This is not a DIY task. Calibration requires specialized equipment, including specific targets placed at precise distances from the vehicle and an Acura-compatible diagnostic scan tool (like the i-HDS). The procedure aims the camera so it knows exactly where the vehicle is positioned on the road. This must be done by a dealership or a qualified independent shop with ADAS service capabilities.
