Renault / Master II / 2007 - no flashers, central locking, cab lighting, does no

Hello, in Master II from 2007 there were: flashers, emergency lights, cabin lighting (it's under the ceiling), central locking (does not react to the buttons on the key and the switch on the roof lining), the engine does not start, but the starter turns. As if it were an alarm block ... or an immobilizer.

How did it happen .. I started the car, turned on the lights, blower in 2nd gear, probably the radio, reverse and after 3 meters the alarm siren with the emergency lights started .. I was driving like this from 500 meters, the siren stopped howling every few signals, howling more and more quietly until it stopped ... I noticed that I did not have the turn signals, I drove from 1.5km and put out the car on the side of the road. From now on, the car does not start, no flashers, hazard lights, cabin lighting and central locking.
I will add that the low beam works, the blower works, the rear and brake light is on.

I changed the batteries in the key, checked the fuses in the cabin and under the hood, the "alarm spec" dismantled the alarm - no change, no improvement .. The alarm siren probably turned on due to lack of power, it went off for a while on its own batteries .. Probably somewhere there is a short circuit. .

Where to start in this case?

First, carefully check the ground connection to the clamp, body and engine

UCH module on the left side of the steering wheel. He is responsible for all the mess that has occurred with you. Check the power supply on it.

The weight of the clamp, body and engine is OK.

On the UCH module, the power supply is on several wires. I don't know how it should be, where it should be.

I noticed the lack of two fuses on the "+" clamp, originally there should probably be two 40A fuses, for me it is short on the plates.
It also seems to me that there is no original immobilizer, the red diode does not blink on the dashboard, but the key has a key ring that probably imitates the signal of the external immobilizer.



What to do next? What to check ??

I will add that a few days before the fault, an ABS error jumped out, it happened when I was sliding off the curb, the wheel probably turned faster, which caused an ABS error.

Gentlemen, thank you for your help, today I checked the plugs under the clocks, at the steering wheel and under the steering wheel, I checked the fuses again and the fuse from the immobilizer was suspected (under the steering wheel on the left), I replaced it and everything returned to normal, the car fires, the central locking is back, the hazard lights and flashers also come with cabin lighting in the ceiling.

I'll step under the topic.
Hello everyone and please help.

A month ago I bought a Renault master with a damaged engine. But before the engine got dead three months earlier, the timing belt had broken and the entire cylinder head was made. The car was done and it was driving Ok. And as I wrote after two months, suddenly while driving lost power, began to smoke and something began to look in the engine. The car was towed to the workshop that did the head renovation. The workshop refused to repair claiming that it has nothing to do with repairing it. I took the car and decided to check what happened. I removed the timing cover and everything became clear. The roller supporting the lever was cracked in two places (I attach the photo) one broken bolt and two loose. After watching the shar it turned out that they were ordinary ones from "Castorama" of low hardness. I bought the whole shaft with levers and original screws and replaced it. I twisted everything, I bled and ....... it doesn't fire. He smokes on PLAK. Help. I would add that before the replacement of the roller, the car even with a crack fired on the arrow but worked unevenly and after a while went out.
