Experiencingdashboard lights like ABS, Electronic Steering, TPMS, and skid control illuminating all at once in your Honda Accord can be unsettling. Often, these simultaneous warnings point towards a failure in your Anti-lock Braking System (ABS) module, specifically the electronic component. While a complete ABS module replacement can be costly and involve bleeding all four brakes, there’s often a more straightforward solution: replacing just the electronic module. This approach not only saves time and potential mess but can be a more budget-friendly fix. And for accurate diagnosis and ensuring the issue is resolved, a reliable Rewritable Car Scanner can be an invaluable tool in your garage.
Spotting the Signs of Electronic ABS Module Failure
How do you know if it’s the electronic module causing the trouble? Certain error codes are strong indicators. If your car scanner – ideally a rewritable car scanner capable of reading detailed ABS codes – is showing codes like:
- 83-11 – ABS ECU/ISU Failure
- 61-11 – ABS Power Source Failure for ECU (Low voltage)
- 85-01 – Electronic power steering VSA signal failure
- 38-11 – ABS Solenoid valve malfunction
These codes, especially when appearing together with the aforementioned warning lights, strongly suggest an electronic malfunction within the ABS module. These systems are interconnected, so a failure in the ABS module’s electronics can cascade into issues with steering, tire pressure monitoring, and vehicle stability assist.
The Simpler Solution: Electronic Module Swap
The good news is that the electronic module is often detachable from the hydraulic valve/pump body and pump motor of the ABS module. This clever design allows you to replace just the electronics, leaving the hydraulic components undisturbed. The advantage here is significant: you avoid the need to bleed the entire brake system, a process that can be time-consuming and require specialized tools. Furthermore, you minimize brake fluid spillage, keeping your garage cleaner.
While the physical removal and replacement of the electronic module isn’t overly complex, it does require some patience and dexterity. Aligning the pump connectors with the electronics module as you reassemble it through the valve body can be a bit tricky, especially if the valve body remains connected to the brake lines in the car. For visual guidance, numerous online resources, including YouTube videos, offer step-by-step tutorials on this process. These videos can be incredibly helpful in navigating the nuances of the replacement.

Decoding the Part Number Puzzle
Finding a replacement electronic module can be where things get a bit complicated. ABS modules, and their electronic components, are not universally interchangeable. Part numbers vary depending on the trim level and year of your Honda Accord. To further complicate matters, the module itself usually only displays a partial part number.
For 9th generation Honda Accords (like the 2013-2017 models), the generic VSA modulator part number typically starts with 57110-T2F-xxx, where “xxx” represents a specific letter and two-number combination. The red numbers printed on the actual module are often the only visible identifier and your best clue when searching for a compatible part from used sources or online marketplaces.
To illustrate part number variations, for a 2016-2017 Honda Accord with a K24 4-cylinder engine, the following module codes have been identified:
- T2F-X0: LX trim only
- T2F-X1: EX trim only
- T2F-X2: Sport trim (compatible)
- T2F-X3: LX trim only
- T2F-X4: EX trim only
- T2F-X5: Sport trim (compatible)
It appears there was a mid-year update in part numbers, but according to Honda parts information, the later, higher-numbered modules are compatible with the earlier ones within the same trim. Therefore, for a 2016 Sport model, either a T2F-X2 or T2F-X5 marked VSA modulator electronic module should be compatible.
Keep in mind that modules for other model years are different. You’ll need to do some detective work using online Honda parts websites, or consult with a Honda parts specialist to determine the correct part number for your specific vehicle. For instance, a 2013 Accord LX requires a T2F-A0 modulator. Double-check compatibility before ordering to avoid wasting time and money on an incompatible part. An incorrect module will not resolve the issue, and the error codes will persist, even if you use a rewritable car scanner to attempt to clear them.
Navigating the Used Parts Market
Online marketplaces like eBay can be a source for used ABS modules, but proceed with caution. Many listings are poorly documented, making it difficult to ascertain the exact part number and compatibility. Do not solely rely on eBay’s built-in “fitment” tool, as it may incorrectly suggest universal compatibility across all 2016 Accord trims, for example. Carefully examine listing photos for the partial part number on the module itself and cross-reference it with reliable Honda parts information.
Next Steps and Investigating the Failed Module
After ordering and installing your replacement electronic module, using a rewritable car scanner to clear any stored error codes is a crucial step. This will ensure the warning lights are extinguished and the system is functioning correctly.
Furthermore, consider disassembling your old electronic module. Common culprits for failure in these modules include cracked wires and solder joints. If you possess soldering skills, repairing these issues might be a straightforward DIY fix, potentially giving you a spare module or helping you understand the failure mechanism.
By understanding the nuances of ABS electronic module replacement and utilizing tools like rewritable car scanners for diagnostics and code clearing, you can tackle this repair effectively and potentially save significant costs.
