In detail: DIY peugeot 307 abs block repair from a real master for the site my.housecope.com.
It turned out to be much sadder (((((, I opened this block, bought during disassembly, it turned out that there on the mikruh such thin hairs are attached to the plug on one side, and on the other go to the mains, so 5 of them were cut off, I soldered, the car began to start, but as soon as I press the brake, then errors on the abs and on the internal combustion engine pop up, they disappear a little, I decided to rewire this mikruhu from my old block to the one that was disassembled, it all worked, there are no errors, but errors appeared on the p0350 engine, a malfunction of the primary secondary circuit of the ignition coil, and if it is not reset after a day, a whole tragedy begins, errors come out on the rear oxygen sensor, then on the injectors, as a result, the adsorber valve stops working and the tank sucks in such a way that the gasoline arrow starts from scratch half rises, in short, this fawn gave me up, decided to change the ignition coil, I have 4 of them, one from a Citroen, one old, one bought a month ago, and bought one a week ago, ITO D: what kind of reel do not put the error after starting the car in 3 seconds it comes out, I'm in a dead end, I think! Can the ABS unit influence this, maybe I messed up with contacts, or it has other malfunctions, although there are no abs errors and it works properly.
Basically, if you have a mechanic, I can rewrite the numbers from my block. I have the same year, motor, etc. Somehow I also tried to choose an ABS unit for myself, it's not a rewarding business. They had 6 varieties per year, which are not replaced by each other. And yet, there was a block that I bought during disassembly, I will give it for inexpensive)

ABS unit numbers to be repaired (if your block number is not among the numbers presented below, it does not mean that its repair is impossible - call!) :
Cars on which the above-mentioned ABS control units were installed:
PEUGEOT 406 1997 - 2002 model year
PEUGEOT 605 1997 - 2002 model year
To diagnose the above malfunction of the Peugeot car (Peugeot), you can drive up to our car service. The equipment used by us in the diagnostics is dealer and allows the most complete and accurate identification of the vehicle malfunction.
Automakers strive to make their products as safe as possible for consumers. For this, almost every vehicle receives a set of all new electronics and other automation units. The presence of ABS in the design of the car can hardly surprise anyone. However, with an increase in the number of nodes in a car, the likelihood of failures also increases. You have to learn how to repair the ABS unit.
Some drivers simply "swing" the contacts away from this node, but this solution reduces the level of driving safety. This is especially important when driving in the off-season and on slippery roads.
ABS's job is to keep the machine moving in a straight line in critical situations. When the vehicle is braked sharply, this unit does not allow the wheels to be completely blocked. Thus, the vehicle does not skid. This feature is often helpful when maneuvering on slippery roads.
The anti-lock braking system includes the following components:
several sensors located on the wheels;
electronic control unit responsible for turning on / off individual elements;
an indicator light installed on the dashboard by the car manufacturer.
Electronics also monitors the health of the entire complex and the resulting defects during operation. If they occur, a warning light appears on the dashboard, notifying of the problem. After that, you will need to do ABS repairs with your own hands or contact a service station for help. The second option will be more expensive. Most often, they offer to completely replace the block, and not bother with figuring out the exact place of an open circuit or an inoperative element.
When the driver turns the key in the ignition lock, the computer system diagnoses the operability of the main components through the sensor system. It is considered normal that the indicator with the inscription "ABS" after turning the key is on for about 3 seconds. Further, it should go out in confirmation of the unit's serviceability.
When fading does not occur or the light comes on while driving, then you must perform the following actions:
We park the vehicle in the nearest permitted area.
Using a multimeter, we diagnose the voltage on the battery, which should not be less than 10.5 V.
We check visually and by disconnecting / connecting the contacts on the battery.
We inspect the wires from the ABS sensors for integrity or breakage.
If it did not work out with simple diagnostic methods, then you will need to contact the station for more accurate computer diagnostics. The equipment will determine the error code, decoding which will reveal the malfunction. Further, the defect will only need to be eliminated. In this case, there are two ways: independent or with the help of bus station workers.
Various reasons can cause the indicator light to come on. There are serious problems that cannot be ignored. And it happens that it is enough to clean off the dirt deposit from the sensor, and we can assume that the repair of the ABS sensor with your own hands is practically completed. In any case, a visual assessment of the condition of the sensor must be carried out.
To do this, you need to jack up the wheel. Next, we unscrew the bolts and remove it from the hub. After that, we turn the steering wheel in the opposite direction from the diagnosed wheel. Unscrew the bolts that block access to the sensors.
Clean the sensors from plaque with a clean cloth. It is advisable not to use aggressive chemicals. You can moisten a cloth in a mild soapy solution and then remove the moisture with a dry cloth. Repair with sensors is usually not carried out, and if they have obvious mechanical defects or damage, then such parts must be replaced.
After cleaning, we return everything to its place in the reverse order of disassembly. We check the information from the indicator light on the dashboard. If the issue is resolved, then "ABS" will go out, and if not resolved, then it is necessary to identify problems in the electrical unit.
The main problem associated with the inoperability of the ABS electronic unit is the lack of contacts between the elements. This can arise from mechanical (shock or violent vibration), chemical (corrosion) or electrical problems (overvoltage burned out).
For repairs, you will need to turn off the problem node and take it to the workbench for convenient repair. We carefully open the case with a construction knife. Typically, parts of the plastic housing are glued to seal. We do not run the knife deeply so as not to damage the wiring or other elements.
We identify the place of breakage or other malfunction. Using a pulse soldering iron, we re-solder the damaged wires. A Weller soldering station is also suitable for soldering. The ceramic base must not be overheated, otherwise all work will lead to complete breakdown of the entire board. All that remains is to throw it away.
We collect the block after repair. Then we install it in its place and check for a signal on the dashboard. If the indicator stops constantly on, then the problem is solved.
When an ABS malfunction signal appears on the dashboard, it is worthwhile to check its condition as soon as possible, at least visually. If mechanical cleaning of the sensors did not bring a positive result, then you will need to repair the ABS unit yourself or with the help of specialists. It is not worth delaying the repair, as this system increases driving safety. It is allowed to drive without ABS for some time, but it is better to do it in dry weather, at low speed and on a good road.
Most modern cars are equipped with a set of systems aimed at driving safety. To prevent wheel blocking during heavy braking or on a slippery road, the anti-lock braking system ABS (ABS) is used. Fully locked wheels are known to increase the stopping distance of a car, and if only a few wheels are locked, the car is more likely to skid.
The ABS includes several systems - the anti-lock braking system itself, the stability control system and emergency braking. The whole complex is controlled by an electronic control unit, and the final device is the hydraulic system of the vehicle.
The signals for the operation of the ABS systems come from a sensor installed on each of the wheels and monitoring the rotation of the wheel at each moment of movement. Based on the speed of the vehicle, the speed of rotation of the wheel, the condition of the road surface or the angle of inclination of the road, signals for the control valves of hydraulic systems are generated at the output of the electronic unit.
The ABS system is very important for the safe driving of a car, therefore, before undertaking repairs with your own hands, you need to carefully weigh everything. Diagnostics and repair of blocks of the ABS system in a car service, even if it will cost a little more than with your own hands, will give a guarantee that failures will not occur at the most inopportune time.
This is especially true for those who are accustomed to using the ABS and rely on its performance.
Like most electronic systems, the ABS has primary self-diagnostics that operate when the key is turned.Diagnostics usually takes a few seconds. If after this time no system malfunctions are noticed, the alarm on the dashboard will go out. When the car is moving, the ABS diagnostics works continuously, and when the parameters of the sensors or terminal devices are not included in the tolerance zone, a malfunction alarm is triggered. When signaling a malfunction, it is necessary with special care to find a convenient place to inspect the car or get to the nearest car service, especially in cold weather, when the roads are slippery. Sometimes it happens that a malfunction can be eliminated with your own hands in a couple of tens of minutes.
To repair blocks of the ABS system with your own hands, you must first measure the voltage of the battery. If the voltage is less than 10.5 V, the ABS control unit will not turn on, so that there are no errors in operation. At normal voltage, you will have to continue troubleshooting. Most of them are due to the wiring of the sensors. Moisture, getting into the connectors, causes oxidation of the contacts, therefore, first of all, you need to assess the condition of the contacts of each sensor of the ABS systems.
Very often, breakdowns of ABS systems are caused by a malfunction of the control unit sensors. To operate the ABS sensor, a gear wheel is attached to the hubs, and the sensor itself is an inductor located at a distance of 0.2–1.5 mm from the teeth. If all the teeth are in place, then it is necessary to measure the gaps between them and the sensors, if necessary, readjust the mounting of the sensors. Dirt accumulated on the teeth and surfaces of the sensors can adversely affect the operation of the ABS.
The coils themselves are checked with an ohmmeter. The device should show a resistance of 1-3 kOhm, depending on the type of sensor. The main thing is that they are all the same on one car. If the ABS sensor coil shows an open or short circuit or is very different from the rest, then it needs to be replaced or repaired. One can only advise to check the place of entry of the connecting conductors into the device. Perhaps the wires are broken, and, having removed a little insulation from the sensor, you can try to solder the break or short. Many devices can be disassembled by heating them with an assembly hair dryer and removing the plastic cover at the wire entry point. It is under this cover that breaks occur most often. In this case, do-it-yourself ABS repairs will not be very serious. Considering the cost of the sensor, such a technique may have a right to exist.
