2006 Infiniti M45 ABS Module: Fire Risk Recall, Failures, and Replacement Guide
This guide covers the critical safety recall, common failure symptoms, specific fitment details, and programming requirements for the 2006 M45 ABS pump and module assembly.
- A critical safety recall exists for a leaking ABS module that can cause a fire. If your ABS light is on, park the car outside immediately and have it inspected.
- Compatibility is crucial. Part number 47660EH104 is for RWD models with the Sport Package and without adaptive cruise control.
- Replacement is not plug-and-play. The module must be programmed to the vehicle's VIN and the brake system requires a special bleeding procedure with a scan tool.
- Common failure symptoms include the ABS, VDC, and SLIP lights illuminating on the dash and a loss of anti-lock braking function.
Symptoms of a Failing ABS Module
When the ABS module in a 2006 Infiniti M45 begins to fail, it typically provides clear warnings on the dashboard. Ignoring these signs can compromise the vehicle's safety systems.
- ABS, VDC, and SLIP Lights On: The most common symptom is having the "ABS," "VDC OFF," and "SLIP" warning lights all illuminate on the instrument cluster and stay on. This indicates the computer has detected a fault and has disabled these safety features.
- Brakes Lock Up: With the ABS system disabled, the anti-lock function will not work. In a panic stop, especially on wet or loose surfaces, the wheels can lock completely, causing the vehicle to skid and lose steering control.
- Unusual Brake Pedal Feel: The brake pedal may feel unusually hard to press, or it might feel soft and "spongy." This happens when the module can no longer correctly regulate the hydraulic pressure in the brake lines.
- Pump Motor Runs Constantly: You may hear a humming or buzzing sound from the engine bay, which is the ABS pump motor running continuously, even after the car is turned off. This can drain the battery and indicates a severe internal module failure.
- Inaccurate Speedometer: In some cases, a failing ABS module can cause the speedometer to read incorrectly or stop working altogether, as it relies on data from the wheel speed sensors processed by the module.
Common diagnostic trouble codes (DTCs) associated with ABS module failure include:
- C1142: ABS Pressure Sensor Circuit Fault. This sensor is typically internal to the ABS actuator, requiring the replacement of the entire unit.
- C1109: Often indicates a battery voltage issue or a communication problem between the ABS module and other vehicle systems.
Pro Tip: Before assuming the ABS module is bad, check the brake fluid level. If the fluid is low, it can trigger the VDC and SLIP lights. Topping off the fluid may resolve the issue. If the fluid is low, you likely have worn brake pads or a leak that needs to be addressed.
Critical Safety Recall: Fire Risk
Warning: Many Infiniti vehicles, including some 2006-2007 M35/M45 models, are under a major safety recall for the ABS actuator. The pump seal can leak brake fluid onto the internal electronic circuit board. This can cause an electrical short, which in rare instances, may lead to a fire.
If your ABS warning light comes on and stays illuminated, Infiniti advises you to stop driving the vehicle, park it outdoors away from buildings and other cars, and have it towed to a dealer for inspection. You can check if your specific vehicle is affected by entering your VIN on the NHTSA recall website.
Confirming Compatibility for the 2006 M45
Finding the correct ABS module for the 2006 M45 is critical, as there are several variations. The part number is the most reliable way to ensure a match. The information provided by online parts catalogs can be confusing.
- Part Number 47660EH104: This module fits 2006 M45 models equipped with the Sport Package (which includes 19-inch wheels) and without Adaptive Cruise Control. It is for Rear-Wheel Drive (RWD) models only.
- Part Number 47660-EH64B: This module fits 2006 M45 models without the Sport Package (18-inch wheels) but with Adaptive Cruise Control.
Some parts catalogs mention a production date cutoff of "To 2/05" for a 2006 model year vehicle. This is almost certainly a typo and likely means for vehicles produced up to February 2006. Do not rely on this date; always match the physical part number from your original unit to the replacement.
Buying a Used ABS Control Module
Given the high cost of a new OEM module, a used unit from a reputable recycler is a smart financial choice. However, there are important factors to consider.
- Verify the Part Number: Before purchasing, physically check the part number on your car's existing ABS module. It is located on the electronic portion of the assembly. Ensure it matches the used part exactly.
- Inspect for Damage: Check the electrical connector pins for any signs of corrosion, which could indicate water or brake fluid intrusion. The aluminum hydraulic block should be free of cracks or severe damage.
- Choose OEM Over Aftermarket: For a complex electronic part like this, a used Original Equipment Manufacturer (OEM) unit is often more reliable than a new, cheap aftermarket part. Used OEM modules are designed to integrate perfectly with your vehicle's systems, whereas aftermarket units can have communication and software issues.
- Factor in Programming Costs: Remember that a used module is not a plug-and-play part. It will require professional installation and programming, so factor this cost into your budget.
Installation and Programming Requirements
Replacing the ABS module assembly is a job for an experienced DIYer or a professional shop due to the need for special tools and procedures.
- Brake System Bleeding: The replacement process involves disconnecting hydraulic brake lines. Afterward, the entire brake system must be thoroughly bled to remove all air.
- Scan Tool Required: A professional-grade scan tool (like the dealer's CONSULT tool or a high-end Autel scanner) is necessary to perform an "automated bleed" or "actuator bleed." This procedure cycles the internal solenoids in the ABS pump to purge trapped air that cannot be removed with a standard manual bleed.
- Programming/Initialization: A replacement module (new or used) must be programmed or initialized to the vehicle's VIN. This ensures it can communicate correctly with the engine computer, transmission computer, and other systems. An independent shop with the right equipment can perform this; a dealer visit is not always required.
Replacement Cost Comparison
Prices can vary based on your location and the supplier. The following are estimates to help you understand the value of different options.
| Part Type | Estimated Cost |
|---|---|
| New OEM | $1600 - $1900 |
| Remanufactured | $300 - $500 |
| Used OEM | $90 - $200 |
| Shop Labor | $160 - $250 (for installation and bleeding) |
| Programming/Calibration | $100 - $200 |
Frequently Asked Questions (FAQ)
Can I drive my M45 with a bad ABS module?
You can, but it is not recommended. Your normal hydraulic brakes will still work, but you will not have anti-lock brakes, traction control, or stability control. This significantly reduces safety, especially in emergency situations or bad weather. If the ABS light is on due to the recall, you should park the vehicle immediately due to the fire risk.
Does a used ABS module need to be programmed?
Yes. Any replacement ABS module, whether new or used, must be electronically configured to your car's specific VIN and options. This is not a plug-and-play part. Be wary of sellers claiming to offer "pre-programmed" modules, as this is generally not possible without having the module installed in the vehicle.
Can an independent mechanic replace and program the ABS module?
Yes, a well-equipped independent shop can perform this repair. They must have a professional-grade bidirectional scan tool capable of performing the ABS actuator bleed procedure and the VIN programming/initialization for Nissan/Infiniti vehicles.
What is the difference between the ABS module and the ABS pump?
The ABS module is the black electronic computer box, while the pump (or actuator) is the metal hydraulic block with the brake line connections. For the 2006 M45, they are sold and replaced as a single unit called the ABS actuator assembly.
