Partner Tepee 1.6 HDI 2010 - ABS / STOP / Handbrake indicator after firing

I warmly welcome

After starting the engine, the ABS / STOP / Handbrake indicators light up, and ABS / Braking System Faulty appears on the center console display. When connecting to the diagnoscope, an error is displayed (I do not remember the number) - A momentary lack of power to the ABS pump (description from the memory), according to the mechanic, it could be a dirty plug. I treated the plugin WD40. The lights are still on after starting the engine.

I would add that the car stood under the cloud for about 3-4 months, with the battery running out, after removing and charging the lights came on after the first start.

Check all fuses and masses carefully. Then check the correctness of the ABS supply.

I will check, do you know the pinout of the plug coming to the pump and the exact fuse distribution? Carefully I checked all in the box under the hood, they are functional. I haven't checked the wheel yet.

All fuses under the steering wheel and in the engine compartment (box next to the accumulator) checked and working.

The weight is checked and seems OK. How can you check the ABS power supply? Removing the plug from the pump means that even the ignition cannot be turned on, and the LCD displays a message about the braking system failure and, interestingly, about the "depollution system" failure.

After thoroughly cleaning the ABS pump's power plug, the problem resolved, thanks for the help.
