2022-2023 Acura TLX Infotainment Module: Blank Screens, Reboots, and Type S Compatibility

Symptoms of a Failing or Glitching Infotainment System

Problems with the infotainment system in the 2022-2023 Acura TLX are common, but they don't always mean the control module has failed. Many issues are software-related and can be temporarily fixed with a system reboot.

• Blank or Black Screen: The screen fails to turn on at startup or goes black intermittently while driving. In some cases, audio may still play. This is one of the most frequently reported issues.
• System Freezing or Unresponsive: The display is stuck on a single screen, and inputs from the touchpad do not register.
• Constant Rebooting: The system continuously restarts on its own, often showing the Acura logo repeatedly.
• Apple CarPlay / Android Auto Issues: The system fails to recognize a connected phone, frequently disconnects, or freezes when using CarPlay or Android Auto.
• Popping or Crackling from Speakers: Audio is distorted by popping or crackling sounds, which may occur alongside the screen going blank.
• System Won't Turn Off: The screen's backlight remains on even after the car is turned off and locked, potentially draining the battery.

First Step: Try a System Reboot

Before assuming the hardware is bad, a system reboot can often resolve temporary software glitches. There are two main ways to do this:

1. Soft Reboot (While Driving): Press and hold the three buttons at the top of the touchpad (Back, Home, and Card) simultaneously for a few seconds. This will bring up a dealer diagnostic screen. Select 'Detail Information & Setting', then 'Hardware Auto Detect'. Without changing any settings, press 'Apply' and confirm the restart. This reboots the system without clearing your settings.
2. Hard Reboot: The simplest way to perform a hard reboot is to turn the car off, open and close the driver's door, and then restart the car. For a more thorough reset, you can disconnect the negative terminal of the vehicle's battery for about 10 minutes. This will force a complete power cycle of all vehicle electronics.

Known Issues, TSBs, and Warranty Extensions

Acura has acknowledged several issues related to the infotainment system and its components through Technical Service Bulletins (TSBs) and warranty extensions.

TSB 23-030 / Warranty Extension 24-046: Popping/Crackling Speakers and Blank Display

Acura initially released TSB 23-030 to address complaints of popping/crackling audio and the display going blank on 2021-2023 TLX models. This bulletin was later superseded by Warranty Extension 24-046, which extends the warranty coverage for this specific issue. The problem is often traced to faulty FAKRA service cables connecting the components. If your vehicle exhibits these exact symptoms, contact an Acura dealer to check for eligibility under this warranty extension, as the repair may be covered at no cost.

Buying a Used 2022-2023 TLX Infotainment Module

If a system reboot or TSB-related repair doesn't solve your problem, you may need to replace the control module. Buying a used OEM unit can offer significant savings over a new part from the dealer.

• Verify the Part Number: The only verified OEM part number for the 2022-2023 TLX Type S is 39540-TGZ-A23 (or 39540TGZA23). Do not purchase a module with a different part number, as it will not be compatible.
• Heed the Compatibility Warning: Double-check that the donor vehicle was a Type S model and did not have the High Performance Tire Option. This is a specific and critical compatibility requirement. The reason for this is likely due to different software needed to support features bundled with that option.
• Physical Inspection: When buying a used module, inspect it for any signs of physical damage, especially to the connectors. Ensure all connector pins are straight and free of corrosion.
• Source from a Reputable Seller: Purchase from a dismantler or seller who offers a warranty and can provide information about the donor vehicle. A 1-year warranty is a good sign of a quality part.

Programming and Installation Requirements

Replacing electronic modules in modern vehicles is rarely a simple plug-and-play process.

A dealer visit or a visit to a specialized shop is almost certainly required after installing a used infotainment module. While new Honda/Acura modules often come pre-programmed, a used unit is programmed to the VIN and option list of its original vehicle. To function correctly in a new vehicle, it needs to be initialized and configured using Acura's diagnostic software (the i-HDS). This procedure ensures that features like navigation, the correct trim-level splash screen, and integration with other vehicle systems work properly. An independent shop with an up-to-date J2534 pass-thru device and a subscription to Acura's software may be able to perform the programming, but you should confirm this with them beforehand.
