Today we would like to talk about the problems of ABS pumps in Fords.
The material will be divided into two parts, where we will discuss the hydraulic part, i.e. the hydroaggregate block, and the second part, where we will discuss problems with the controller.
The hydroagregator block is a part that has many channels inside where brake fluid flows under high pressure. It is blocked by valves to prevent the wheels from skidding. In versions with ESP, it also has a pressure sensor.
Let's start with the symptoms. Customers often call and say they have a problem with the brake pedal being soft or slipping, or having a problem with the wheel locking up for a few seconds after releasing it. The car pulls to the right or left or brakes erratically. In the worst case, the wheel locks or does not brake at all. Most often, these are two wheels crosswise, for example, left front and right rear, or vice versa. We also once had a case where the customer replaced a set of brake discs and they came off very quickly, which may also be a symptom of faulty hydraulics.
The cause of these symptoms may be the brake fluid not being replaced, the brake system not being cleaned or having air in it. Of course, there may be problems with the calipers, brake lines, brake master cylinder or servo, but if they have already been checked, it is very likely that the hydro generator pump is broken. Our current record holder is the ATE MK100 pump, which seized up after just 33,000 kilometers.
What can we do about this problem? There are two options. First - replacing the hydraulics with another one. Unfortunately, this is not always a good option, because some models have a pressure sensor that is assigned to the controller. The second option is to repair such hydraulics with us, which is simpler and cheaper due to the decreasing availability of parts.
If we have already discussed the hydroaggregate pump, we can move on to the second part of the material, more precisely to the ABS pump controller, i.e. the electronic part. If the ABS light comes on in your car, the first thing you need to do is go to a mechanic for car diagnostics. You should read the error codes from the ABS controller and the numbers of this controller.
Once we have this information, you can call us for a consultation whether the fault can be repaired. Unfortunately, electronic problems are much worse than hydraulic ones because some of them cannot be repaired. Nevertheless, most things can be done.
Now let's move on to discussing the types of pumps. Unfortunately, a lot of them have been installed in Fords over the years.
The first pumps were ATE MK20 and MK25.
These are pumps from the 1990s and early 2000s. There were mainly two problems with these pumps:
- C1095 - Motor relay
- B1342 - Control module failure
These are errors that can easily be fixed.
The next ABS pump is the ATE MK60. They occurred from 2002 to 2008.
Here we see a larger number of faults that could occur in the controller. To be precise:
- C1288 - Pressure sensor - circuit damaged
- C1267 - Control unit internal error
- C1095 - Motor relay
- C0044 - Brake pressure sensor circuit damaged
After 2008, the next generation of MK60 pumps came and this is the so-called MK61 or MK60.1 pump
Error problems were common in these pump models
- U3000 - Internal driver error and
- C0020 - ABS pump motor (damaged circuit)
Another proATE's product was the ABS MK100, which has been available since 2013 until now.
Here, electronic problems are very rare and, if they do occur, they are currently beyond repair. The main problem here is with hydraulics, which was discussed at the beginning of the material.
Bosch 5.3 or 5.4 pumps were also installed in Fords, which, among other things, broke down due to wheel sensor errors and lack of communication with the module.
When it comes to the Bosch 8.0 pump, the most common faults are:
- 5D8D - Return pump
- 5B02 / 1B02 - Pump motor / motor relay damaged - this error could result in the engine running all the time.
There were also occasional problems with lack of communication with the ABS controller.
We will end with this pump, because there were other ABS pumps, but in smaller quantities. A good example is the TRW pump, which, similarly to the MK100, had problems mainly with hydraulics.
The symptoms, faults and error codes described here are the most common. So if you have any other error or problem with your ABS pump, please contact us, but before you call, remember these two important things. Write down the number of the ABS controller or pump and read the error codes if the ABS light on the dashboard is on.
