FIAT BRAVA 182 Fiat Bravo 1.4 Airbag Problem

I have a problem with my airbag The red light (for airbag) doesnt want to turn off after i turn the car on. I went to a fiat car service and they said that the main plate for airbag is dead...I am not so sure it can be only the problem with some bad connection at connectors (like in Renault clios case where the connectors are under the seat). Namely my light has started to lit after i have washed and

FIAT BRAVA 182 Would love somebody who can solve the problems with my brava

I have two hot issues One problem Ive had it for 4 years now and nobody can solve it for me so I would love your help before I have to buy a new ECU like Ive been advised. Each morning I drive off with my brava with no probs but if I stop and drive off after an hour (and generally this does not happen after 3 hours) the injector lights come on and only 2 injectors work. The injectors are ok and I feel

Nothing has been changed as each time I took it to fiat garage they tell me that they did not detect anything on the computer I have tried but now I have found a mechanic who works on fiats and he told me that it needs repairing - he thinks it is the ECU and told me that probably I need to change it - but besides it is expensive I want to try other cheaper possibilities which might work. Thanks for your interest.

not sparking are due to coil failure - they generally work in pairs. Dont know about injectors though... About the oil light you say if you brake and stop it comes on - do you mean if you stop and the engine idles then it comes on And if you just rev the engine without driving off does it go out If so then it could be a worn bottom end of the engine or a faulty oil pump. Or the switch. So the brava

My car is very temperamental when it is cold its fine but as soon as she warms there are times where she struggles to pull of and she has a flat spotuntil about 3500 rpm and then she will start pulling like crazy there are other times where even after she has warmed up she is perfect there is nothing wrong with her tis problem is very intermittent any suggestions as to what this might be i have already

Hi Ben Now im no expert on fiats but am used to other makes of car and am quite logical... Sounds to me like the cold start system isnt working. I assume that once warmed up the car re-starts ok Normally my first point of call would be a CTS sensor (Coolant Temperature Sensor) This sensor registers how cold the car is and sends the signal to the ECU (computer) this then applies more fuel and less

FIAT BRAVA 182 Engine upgrade to gasoline on Bravo.... problem

Hi there I have fiat Bravo 1.6 16v from 12.96. Everything was fine. Because I make about 20-30 kkm during year I decided to upgrade my Bravo on BRC gasoline.

FIAT BRAVA 182 Fuel Injection Light Intermittant Starting & Power Problems

Hi everyone Just joined this forum in the hope that someone can give me some ideas what is going on with my fiat Bravo Trofeo (W-reg). Im no mechanic Im afraid so my descriptions are bound to be limited Id noticed a few days ago that the power to accelerate would disappear when driving (scary at junctions roundabouts etc). Seemed to happen more often from cold than when the car had warmed up. No warning

Hi Jug Yes all pretty scary at the time... the airbag warning light had come on just prior to the car needing a service (and before we were planning to go on holiday to Ireland) so I had specifically told the fiat garage to look into it when I put it in. I was then told that they hadnt had time but that it is was OK they see this type of thing quite often and it was safe. I was told to get it booked

FIAT BRAVA 182 Help Immobilizer problem after battery change

A rainy saturday sees me driving through the countryside when the keycode light comes on. [I now understand thats a diagnostic indicator]. Anyway as many of you will have already guessed the battery had died so after a jump start I had a new battery installed and car started fine at the garage. But I get home - and no restarting. Code light comes on and stays on and starting is lots of turning over

I think its all been said really. Though if you turn on ignition and code light comes on it means the keyimmoECU are not communicating and it only needs about 4 wires to accomplish this task. The fiat dealers are going to say computer says immo fault no red key so cant change immo alone therefore you need ECU immo lock and keyset. What ECU you have I might have one here.

FIAT BRAVA 182 Injector Problem

I have a T reg brava 1.6 100 HSX and recently the injector light came on prior to it coming on it came on intermittantly but not for long and this lasted about a week. it sounds like it is only firing on 3 cylinders and I was thinking that in could be a damaged spark plug or dirty plugs or maybe some dirt in the injectors themselves. i am going to be giving the car a full service soon and for the time

i agree engines were a lot easier to work on in the old days. id still prefer a twin carb. these days its more like fixing a computer than a car. sensors everywhere ecu controlled everything. its a nightmare unless you have a diagnostics computer.

FIAT BRAVA 182 Starting Problems

Hi im finally back after getting my mobo rmad.The car(brava 1.6 16v 1996) is now running fine but has developed a new fault . When its been run and stopped it can be hard to restart it. It acts as though the battery is flat (Its fine) and its unable to turn the engine over. If put in gear and the handbrake is released so that she rolls to a halt against the engine as it were 7 times out of 10 shell start....Briskly. Just cant understand it any ideas anyone

FIAT BRAVA 182 Same problem.....

different forum member I brought a second hand brava a few weeks ago and the problems have already started with the ECU . My friend has taken it back and when the diagnostics machine was plugged in it said that we needed 2 blue keys to be reprogrammed (we were only reprogramming one). So she spoke to fiat got another key sent through took it to a local key cutter and went to reprogram the key. Keys

When you go to a good key cutter they have a machine to read and transfer codes. All that the ecu does is learn the codes it doesnt transfer the codes into the key. ECU is a computer whose codes sequence keeps on changing (its all complex electronics). All that the red key does is that opens the programming circuit of the ecu to make the ecu learn the new codes in the blue key. I am not sure but just

FIAT BRAVA 182 Intermittent power loss on 1.6 petrol engine

My 1999 brava suffers from power loss. Sometimes the power is normal sometimes weakened regardless of weather or engine temperature. Spark plugs and lambda sensor have been replaced recently. I took the car to an authorized fiat service center they said computer shows bad knock sensor but they didnt have a replacement on stock so I took the car home. The knock sensor seems well fastened. I disconnected

part of ecu . On the picture only 2 rows of pins are shown. There is obviously something wrong here because my ecu has 4 rows of pins as you can see on attached picture. And the wires from knock sensor are attached to the other ecu compartment (the small one) I just cant tell to which pins. Could anybody with a Haynes manual look this up for me please Attached Thumbnails   __________________ fiat

Misfiring in a modern ECU equipped engine is almost always ignition or fuel injection failure due to bad sensor(s). So you have to be a computerfreak to read the ECU or you have to go to the dealer to have it done. I did the last took less than 10 minutes and was free of charge Did you go to a fiat dealer already with your misfiring problem If you didnt I suggest you do have your ECU read by the fiat Factory Examinizer computer its the easiest way to solve the problem

can anyone help ive just purchase a brava14 12v on a r reg bring it homeit cut out and would not restart so got it towed home once it cooled down it started ok until it got warm then cut out again and this has happen since once it cooled down it will start for about 10 minutes HELP ANYONE PLEASE

As mentioned you cant replace the ECU although it does sound like a problem with the engine management system. Also as mentioned you can go through the system replacing sensors until you resolve the issue starting with the crank sensor. Alternatively you can pay fiat to plug a computer into your car and do a diagnostic so you know exactly what part to replace. There is a third way if you have basic

FIAT PUNTO brava engine into punto

i have a 1.2 sporting punto 16 valve i want to replace the 1.2 engine with a 1.6 16valve brava engine.. i was wondering if anyone can help.. how do i go about changing the wiring loom do i need to change anything else aswel as the loom any info appreciated

First check with the insurance to see what they demand. You will need as much as possible from the brava - Engine box driveshafts hubs and brakes ECU body computer dash panel (speedo etc) wiring loom. It will probably always have an ABS problem as systems wont be compatible. If you dont have the fully running brava dont bother. If you do why bother to do the swap. Sell them both and get an HGT Punto.

Hi Because of some alternator problem of my car the battery was left disconnected for weeks. The alternator has been changed recently.

This is all quite normal. The injector light is lit by the ECU whenever a sensor is not providing a signal within the correct range or not providing a signal at all (i.e. wire broke off).
