Today, I fitted a second rebuilt ABS module that I had purchased. I’m at battle with my ABS module right now. I had hoped this would be the last chapter because the seller has been fantastic in resolving a number of problems. The gods of modules are not, however, smiling upon me once more. I therefore need some advice.
attempted to read the data streams in order to see the wheel sensor and brake pressure, two issues I had been battling. Strangely, the reader refused to show them. Okay, I told myself; programming is required for the module.
plugged in my handy cable and started NCS expert ( as I have done before because it is light years faster than DIS SSSProgram). I navigated the menus to load the VIN and related information, but when I tried to execute the programming, I received a three-part notice saying that I couldn’t communicate with the module. I tried to read but got the same result.
Launch SSSProgram and wait for the VM to start up for the program to prepare before waiting some more. went through the options, and when the list of modules to program eventually appeared, the DSC was grayed out (unselectable). I tried a number of various ways to get around this, but to no avail.
So I’m having a beer and scratching my head. Would appreciate a suggestion or two.
You might, but not always, need to decipher the codes. A steering angle sensor calibration is also necessary before any module swap.
You code the module with this if it is a previously used module that has been coded.
After more review, I used NCS Expert to go through everything again with the new module. No joy; unable to contact module. I inserted the old module again, using NCS expert, and performed a read; everything is in order. Again, I have a problematic module. Sigh.
Ensure that your cable’s OBD pins 7 and 8 are connected. Check the ohms scale with a DMM. If they are connected, the resistance should be 0.
NCSExpert cannot calibrate the steering angle sensor or the code if you are unable to interface with the module.

Bummer. To ensure that your connection is in excellent condition and the module is communicating, it is ALWAYS a good idea to perform the basic INPA “check codes” first while coding (and to see what errors might be there and to clear them). Once there is good communication between you and the module and any mistakes are understood, you may start coding.
It appears that your module provider is a clown show. Sorry. Remain for the wine, BBA.
The connections and cable are both nice. Putting the old module back in proved that I could read/code it at will. In the hopes that the steering angle sensor was the source of the warning lights, I replaced the original module. Since the defective SA sensor had worn-out brushes, I really replaced it.

Hey guys, I had my automobile checked according to an Indianapolis technician. My abs/dsc module might be broken, he suggested. My issue is that it appears to engage my rear brakes without applying braking pressure. Therefore, as I am driving, the rears begin to stick or brake erratically. The issue is solved after removing the entire module. To fix the issue and keep my car drivable, I had to pull the module fuse.
Now that I’ve purchased an entire ABS/DSC pump and module from another 335 on eBay sans M Sport brakes, more research indicates that I might need to code the new module to my specific vehicle.
So, I want to know if anyone can offer any advice or assistance on how to code a new module for the car.
For E-Sys:
Hello, Murd0x I’m having the same same issue right now and am unsure which fuse to pull to turn off the module and make the car driveable. Many thanks!!

Guys I’ve discovered some helpful do-it-yourself guidelines for coding a pre-owned or brand-new ABS module, but I’m not entirely sure what I need in terms of hardware and software. I downloaded a user’s manual for NCP Expert. However, I’d like to know what I need to connect to my 2000 E39 528i securely. My laptop has a USB port instead of a serial port and Windows 7. But I also have an earlier model with WinXP that just has a USB port and no serial port. Furthermore, do I need to utilize the pacman port or the OBDII port under the hood?
Is coding only possible on a PC? Is it possible to use any kind of diagnostic tool for it? I would probably be utilizing a rebuilt or used unit. Additionally, I’m interested in tips, success stories, and experiences. I sincerely appreciate any assistance.
I want to do this since in Toronto whenever I trusted a technician with my car, they either made a mistake or weren’t trustworthy. The thiefship demanded $500 from me for only the re-coding and a full day’s use of the automobile. Everyone on the forum claims it can be completed in 20 to 30 minutes. Why do they require the car for the entire day?
An ABS module is what?
A vehicle’s antilock braking system’s control module, or ABS, is a microprocessor that performs diagnostic tests and analyzes data from wheel-speed sensors and the hydraulic braking system to decide when to release braking pressure at a wheel that is ready to lock up and begin sliding. Since electronic stability control has been required since 2012, antilock brakes, which have been on the market since the 1980s, are a standard feature on all vehicles built after that year. Stability control intervenes to stop skids even when the brakes are not applied, and antilock systems prevent skids when using the brakes. Every time a car is started, an ABS warning light is designed to illuminate for a short period of time. If the light illuminates while the car is in motion, however, something has gone wrong with the control module, a wheel sensor, or another component. When the warning light is on, the brakes should still function normally on many cars, but the antilock feature won’t. On some vehicles, however, if the antilock system fails, the ability to brake will be decreased, and stability control and traction control (on vehicles that have those features) may also be turned off. To assist mechanics in identifying the issue, an ABS warning light typically generates a trouble code that can be read using a diagnostic equipment.
Is it possible to reprogram a used ABS module?
Following discussion, we believe a used ABS control unit would work with your vehicle and wouldn’t require any programming. Actually, because it can only be programmed once, it will always be set to the original vehicle. However, given that they are comparable cars, it won’t matter. It must be coded, which is a minor problem.
Does programming of ABS control modules need to be done?
In reality, an ABS module is made up of three parts: a brake line block, an electrical module with electrical solenoids, and a pump motor that generates pressure in the brake lines for usage during ABS braking circumstances.
It might be a difficult process to replace an ABS module. This module has caution signs written all over it and has an ominous appearance. If you find that you need to remove the brake lines, do so with caution because they contain high pressures.
- Not all ABS units necessitate removing the brake lines. The automaker of the vehicle you are working on will determine this. The steps for changing an ABS module are essentially the same, with the exception of the removal of the brake lines.
Once all of the components are in place, the ABS module needs to be programmed. The manufacturer will also have a big impact on how this process varies.
- Advice: To identify the precise programming technique for this stage of the ABS module replacement operation, consult the manufacturer’s instructions.
The solenoid block and module may need to be replaced together on occasion, or they may not. This depends on the layout and design of the ABS unit, which is determined by the manufacturer’s design, construction decisions, and marketing strategies for the replacement module.
How much does programming an ABS module cost?
A few weeks ago, my ABS warning light began to illuminate, but I have been delaying repairs until I have the money. What will the cost be to repair my car’s anti-lock brakes?
In less than two minutes, find out if your auto insurance is being overcharged.
I regret to inform you that the ABS control module system is broken. Depending on the price of the control module and how hard it is to obtain, the total cost of materials and labor to replace an ABS control module can range from $320 to $1,000.
Even though it will be expensive, you should change your car’s ABS control module if:
- Even when you are driving normally, the brakes lock up.
- Your brake pedals don’t work.
- Your car’s speedometer quits working.
If you choose to continue driving without an ABS control module, you run the risk of losing steering control if your tires lock up or having a complete brake failure. Cutting corners on necessary auto maintenance might lead to a costly auto accident that will cost more to repair than the original problem.

How much does a BMW ABS repair cost?
Best in Automotive Repair Replacement ABS control modules for BMW 328i models typically cost between $1,638 and $1,710. While materials are priced at $1,359, labor costs are predicted to range from $279 to $352. Taxes and levies are not included in this range, nor are your particular model year or special location taken into account.
What leads to ABS module failure?
If there is an issue with the ABS system, a warning light on the vehicle’s control module is intended to alert the driver. An issue with the module or ABS itself happens infrequently. One or more sensors, or the connections to the sensors, are frequently to blame. The majority of ABS issues arise when metal shavings or other particles contaminate sensors.
When sensor wiring is harmed, malfunctions also happen and there is sporadic or no continuity. The hydraulic control unit can stop working when brake fluid becomes polluted due to more corrosive circumstances or serious braking system neglect.
Physically inspect the wiring and the brake sensors first if the ABS is acting up. Look for metal shavings and other debris that could give the electronic ABS controller misleading feedback when inspecting the brake sensors. False feedback makes the ABS perform improperly or trigger when it should not.
Any good repair shop will have an ABS scan tool, even if you don’t have one at home. If you can’t identify a physical cause for your ABS problems, the scan tool is invaluable. You can start your ABS troubleshooting after the scan tool generates a fault code. Any issue may be fixed considerably more easily once a fault has been found.
