BRC Just Gas Installation: All LEDs Blink Simultaneously on Gas Level Indicator - Possible Causes

Question

Hello colleagues, I have a problem with my BRC installation, namely when I start the ignition, the LEDs that should normally indicate the gas level are blinking all together and so on. I checked the connection (probably the gas sensor in the cylinder) with the control unit and it's ok. You...

Connect an ohmmeter to the sensor leads. The sensor value should be between 0 - 90 ohms. Move the sensor pointer with the magnet.

sztywny13 · Answer

Break in the circuit, overfilling the tank or damaged indication sensor.

bodzio667 · Answer

When it comes to overfilling the reservoir, it is rare in our country; P.
So it's out. I would like to ask, then, where is the indication sensor? I have a round cylinder fitted in place of the spare wheel.
I understand that it is in the cylinder and that I have to take out all the gas to remove it, right?

sztywny13 · Answer

The sensor is located on the multivalve. Is it manometer 0-90ohm. You don't have to leave the gas. What does the poet mean? [MS]

MałyMaro · Answer

Do the LEDs flash even when you are low on gas? Perhaps it's just a matter of regulation.

bodzio667 · Answer

The LEDs flash constantly colleagues. Even when there is little or no gas or a lot of gas. :|

I have already cleaned some 2 cables from the tank, what go but I do not know what they are for ... It is only 2 wires.
stiff13 you say where is this pressure gauge? Because I do not see such a multivalve?

unless it's underneath the cylinder, I don't know. As I said, it is mounted in the place of the spare. A gas tube and a cable come out at the bottom of the cylinder. But I don't know what he's there for? Is it some kind of power supply to an induction valve to release gas from a cylinder? I think right?

sztywny13 · Answer

A multivalve is such a contraption with a coil under the tightness cover in the tank. There you will find a sensor (pressure gauge). If the sensor is ok, I would look under the chassis to see if there is any damage to the electric wires.

bodzio667 · Answer

How can I check this sensor ?? If a measure, what result should I get?

mariusa · Answer

Hello .
I have the same problem, maybe - circuit break ??? but how to embrace it? without diagram. at the solenoid valve, I have 4 wires plus and minus and some 2 other wires are polysolized, but during tests with different versions, closed, open does not give anything, the lights are still blinking together, I have half the gas tank the pointer shows so much in the cylinder, the car runs well only this blinking irritates , give me some advice, in addition to the website,

sztywny13 · Answer

I wrote above how to check the sensor.

don_viking · Answer

I also have the same problem, but a different effect sometimes shows well and, for example, two LEDs light up, and in a moment all of them start to blink and so it repeats itself from time to time. The pressure gauge is ok and has its resistance, the cables are good too, so can it cause this effect?

elektryku · Answer

You have a damaged harness.

don_viking · Answer

The problem is that it is good because I checked it. I would like to add that in winter these LEDs blinked practically rarely and showed me well and when it is warm, they still blink.

elektryku · Answer

Check that the cylinder has a good weight.

don_viking · Answer

I checked the weight of the cylinder and it is ok. The pressure gauge hoses are also good because I checked it, but it was not the cause of bad gas level indicator readings in the cylinder. The problem was with the pressure gauge because the tracks on the PCB with the smd elements were rubbed and the contacts sometimes did not connect. With slight shocks, the magnet in the pressure gauge moved vertically and the contacts did not connect. When measuring resistance, the meter read 150 ? over the entire range of the pressure gauge needle movement.

rafik225 · Answer

I have the same. Mianowice, when I turn on the gas, the lights blink 4 times and go out ... only the one that signals the work on PB or LPG, what do you say?

don_viking · Answer

You can probably have a cut wire somewhere under the car, I just hit the curb with the bottom of the car. If you had a broken pressure gauge, either one LED would blink, i.e. the resistance would be close to zero, or all four, i.e. the resistance would be greater than 90? In my case it was 150 ?.

rafik225 · Answer

exactly!! it got worse after my car got stuck on the door sills and my friend dragged me with the thresholds on the ground, maybe then the cable was damaged?

aerodeck71 · Answer

Hello. I have a similar situation as my colleague Bodzio667, but when the LEDs are normal, the car switches to gas, but sometimes the LEDs start flashing and automatically switch me to petrol. I have to stop then, switch off the engine, wait a while and everything returns to normal, although not every time.

don_viking · Answer

As when the fuel LEDs are flashing, the gas level LEDs are also flashing, it means that there may be a problem and if the first LED on the right is flashing, the catalyst probe is malfunctioning, the second from the right - bad connections of the solenoid valves, the third LED on the right - throttle position signal error , the first two on the right, error in the position of the stepper motor, three LEDs on the right, damage to the control unit. Therefore, if the diodes behave as described, I advise you to go to the gas generator and let it check after connecting to the computer what the problem is.

aerodeck71 · Answer

Don viking, I see you know the subject. My switchboard is of the BRC type, where the LEDs are vertical. For me, the situation looks like this: The first LED, which shows whether the engine is running on gas or petrol, flashes in 3 colors, red - yellow - green, alternately, and the LEDs indicating the gas level in the tank are flashing - the first and the last. It is enough for the engine to reach the optimal temperature. I will turn off the car and restart it in a moment, everything is OK. Sometimes it happens that I have to turn the key in the ignition several times so that the LEDs do not go crazy.

don_viking · Answer

It depends on what type of BRC installation you have. Take a look at the forum and ask colleagues because I have not encountered such a symptom.

Or you can check on this page all about the different installations.

aerodeck71 · Answer

I have a Just Heavy installation. Almost 10 years old. I noticed that this may be related to the temperature sensor, because when what I described happens, the engine temp indicator, when I step on the accelerator pedal, the pointer drops to zero. This happens until the engine reaches its optimal operating temperature. Let me just mention that I drive a Mitsubishi Galant.

oscar99 · Answer

Hello
I have the same problem as the aerodeck71, I start the engine on petrol and it's ok, the red diode is on until the engine warms up a bit, the diodes start blinking, the red diode changes to orange, they turn off some error and will not switch to gas. the engine is already well warmed up, I have to turn it off and restart it then everything works normally, the LEDs do not flash, the green LED is on and I can go on gas. again. What's the problem? I have a Ford Mondeo 1.8 installation Brc Just Heavy 10 years.

Hello, and I have a question, is it possible to fix this reserve indicator somehow or do you need to replace it with a new one?

Strumien swiadomosci swia · Answer

It is a level indicator with no reserve, screwed on with 2 screws.

robaczekp82 · Answer

Well, yes, but it can be repaired, it shows all the time 130 ohms and the new one is about PLN 90

Strumien swiadomosci swia · Answer

If, despite moving the hand, it shows 130om, it doesn't work. You can only insert a $ 17 reserve indicator.

robaczekp82 · Answer

oki but will it then show the gas level in the tank as before?
