2014-2019 Nissan Versa Note ABS Module: Programming, Failure Codes & Replacement

Symptoms of a Failing ABS Module

When the ABS module in a 2014-2019 Versa Note fails, it typically disables the anti-lock braking and related safety systems. While your standard hydraulic brakes will still function, the crucial safety net provided by ABS is lost. Watch for these specific signs:

• ABS Warning Light: The most common symptom is a constantly illuminated ABS warning light on your dashboard. This indicates the onboard computer has logged a fault in the system.
• Traction or Stability Control Light: Because the ABS module manages these systems, you may also see the Vehicle Dynamic Control (VDC) or traction control warning light turn on.
• Wheels Locking Up: The entire purpose of ABS is to prevent wheels from locking and skidding. If your wheels lock up during a hard stop, it's a clear sign the system is inactive.
• Unusual Brake Pedal Feel: In some instances, a failing module can cause the brake pedal to feel unusually hard, spongy, or unresponsive.
• ABS Pump Motor Runs Constantly: You might hear a humming or buzzing noise from the engine bay that doesn't stop, even after the car is turned off. This can be the ABS pump motor running continuously due to a faulty module, which can drain the battery.

Common Diagnostic Trouble Codes (DTCs)

To properly diagnose the issue, a technician will use a scan tool capable of reading ABS codes. Codes that frequently point to a failed module include:

• C1110, C1111: These codes often indicate an internal failure, performance issue, or power supply problem within the ABS controller or pump motor circuit.

• U1000, U0121: "U" codes signify a communication failure. These mean the ABS module is not communicating correctly with the vehicle's other computers, a strong indicator of module failure.

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

While searches did not reveal any major safety recalls specifically for ABS module failure on the 2014-2019 Versa Note, it's important to be aware of related information.

• Recalls: The 2014 Versa Note was subject to recalls for issues like incorrect rear seat latch bolts and missing lower body sill bolts, but none directly implicated the ABS control module. Another recall for 2014-2015 models involved a console trim panel that could interfere with braking, but this was not a fault of the ABS system itself.
• Technical Service Bulletins (TSBs): Nissan has issued TSBs that are relevant to diagnosing ABS issues. For example, TSB NTB10-145B provides guidance for diagnosing CAN communication issues when a U1000 code is present, advising against replacing the ABS unit without a full diagnosis. Another TSB, NTB18-058e, addresses CVT issues on the Versa Note and involves reprogramming the Transmission Control Module (TCM), highlighting how module software is critical in these vehicles.

Programming and Calibration: The Most Critical Step

Yes, a replacement ABS control module must be programmed to your vehicle. This is the most important part of the replacement process. The module's software is tied to the vehicle's unique Vehicle Identification Number (VIN) and its specific options (like trim level and tire size).

Installing a module without programming it will result in it not working. The ABS, traction control, and stability control systems will remain disabled, and the warning lights will stay on.

Who Can Program the Module?

• Nissan Dealerships: A dealer can always perform the programming.
• Independent Repair Shops: Many independent shops have the advanced, dealer-level scan tools (like Nissan's CONSULT tool) or high-end aftermarket equivalents required for programming.
• Mobile Programmers: In many areas, mobile automotive technicians specialize in module programming and can come to your home or repair shop to perform the service.

After the module is installed and programmed, the brake system must be bled. This requires the scan tool to cycle the ABS pump and valves to purge all air from the new hydraulic unit. A standard brake bleed is not sufficient.

Buying a Used ABS Control Module

A used OEM module is an excellent, cost-effective alternative to a brand-new unit. However, you must be diligent to ensure you get the right part.

1. Match the Part Number EXACTLY: This is the most crucial step. Locate the part number on your original module and ensure the replacement has the identical number. The provided OEM numbers are 47660-3WC0B, 47660-3WC1B, and 47660-9MD1B. Part number 47660-3WC1B is listed as a replacement for 47660-9MD1B. Also, match any 'Ident' (identification) numbers or letters on the label if present.
2. Physical Inspection: When you receive the used part, inspect it carefully. Look for corrosion on the aluminum block, damage to the plastic electrical connector, and bent or broken pins. Do not install a part that shows signs of physical damage or heavy corrosion.
3. Source from a Reputable Seller: Purchase from an auto recycler that offers a warranty. This protects you in case the part is faulty, as even a visually perfect used electronic part can have internal failures.
4. Why Used OEM is a Smart Choice: A new OEM module from a Nissan dealer can be extremely expensive. Aftermarket options may have questionable reliability or software compatibility issues. A quality-inspected, warrantied used OEM module provides the same factory performance and fitment for a fraction of the price of a new one.
