Banky

Hello pretigious members :D I took plugs off with the assistance of a friend. No spark was notice. Put the car back on Lexia and bingo! I discovered the same thing saw by the dealer about the ECU. The LEXIA RESULTS were written as follow: Status of the ECU: ECU locked Engine immobiliser programming status: Matched ECU (Lexia parameter explanation: engine immobiliser is functioning) Problem detected during transmission of unlocking code: Impossible to read engine immobiliser programming status Parameter detail for "Impossible to read engine immobiliser programming status" = The engine management ECU cannot read the engine immobiliser programmings status. Replace the engine management ECU. I was told the ECU can be reflashed to unlock state. Not guaranteed anyway. I am thinking of changing BSI, Engine ECU, key transponder and see if it will work since the cost is about have of changing only the ECU. However, I am concern about the following: 1.Is it going to work at all? 2. Higher mileage transfer to the car. 3. Transponder code (dealer)to program the key to the bsi. 4. Condition of the ECU. (although I have saved the configuration of my BSI and ECU) Please has anybody done this before. Any advice is welcome.

Thanks kfk. Your advice has been so wonderful. I was thinking there is no way the the ignition coil coould ignite since it has to be taken out before removing the plug. I will try as u have said to remove the plugs when I am back home again this weekend. Every other things work in this car. All the window, central lock, lights work fine. When the key is in ignition position, all light come up as stated in the manual. The battery flashes continuously and steady after some minutes. The engine management light that shown on the dashboard suggests that the ECU of the engine is ok as stated in the manual. However, the manual commented that car could enter standby mode if there is a spark and it will not start. The centre control of the car is the BSI and it can only lock the car. That is why I am I wanted to use my Lexia to reconfigure the BSI. I saw one code under my engine ECU, it is printed in small paper The code is "WB-02-4". It did not work with the BSI so I though it may be for the ECU. This saga will continue again.........Anyway there is a big lesson to learn in all these. Thanks for every contributions.

The ignition coils is directly fitted on the plug in this model. I can hear the spark when someone helped to start the car. I see no need to take off the plug anymore. By the way, I fitted another multifunction display,the car still did not work. It looks as if the information is still stored in the bsi. However, while troubleshooting with Lexia, I saw engine ecu locked to bsi. I don't know if this is normal. In the BSI parameter, it shows economode = active. I try to reconfigure the bsi to reset this to inactive but could not. It is asking of 5 digit code. Any idea how to get this?

Thanks. I will do just that and report back

Youmean I need to get spanner and take off all the plugs os some of them?

Thanks for the advice KFK. I unplogged both the radio and the multifunction display and the car still refused to start. However, I discovered that the number on the display unit is the same number picked up by the Lexia as faulty ECU. Even when I try to check up the engine ECU on the Lexia, it shows that it has no fautlt but the fault is in another ECU (ECU ECRAN). It might worth changing it and see if the car will start. I got the same match (number and model) on ebay. It is a used part taken out of c4. I don't know if there would be need for reprogramming. Any help will be appreciated.

It shows no fault in the immobiliser and engine ECU when I check. I am able to check the ECU parameters. However, it shows below (yellow) that "problem cause by another ECU". IS there any ECU that control the "Multifunction display" where the fault is reported because of non communication with radio. My radio is working but though the radio seems to have been changed by previous owner. But the car works with it.

HI everybody. I connected the lexia 3 to the car. Good software (Lexia 347). It is just amazing the kind of things the software can do. this is the result: BSI -------Dialoque yes, No fault Instrument panel-------Dialoque yes, No fault Radio ------- - - (but the radio is working) Switch module under the steering wheel............Dialoque yes, No fault Airbag............Dialoque yes, No fault Multifunction display..........Dialoque NO, Fault YES I read the multifunction error and it displace: Permanent fault, No communication with radio The ECU ECRAN not communicated. I guess it is the multifunction display ECU. Car still refused to start and ECU mode still display. Apart from that everything still works fine after the diagnosis. The tool is very good. Bought from ebay but proved its usefulness. Any help on the next line of action?

Sorry, an omission. I think the car is driving me nut. she is 2002 model. Petrol engine, manual 1.4cc engine.

Yes. The engine did turn over. It makes a small noise (uuuuuuuu) at the end but never start. Battery removal and waiting on lexia. thanks all.

I left the new battery in the car overnight, although the car did not start but there is no sigh of any drain unlike the old battery. Perhaps, my problem is compounded by bad battery. Still awaiting the Lexia.

A quick update. Fixed a new battery from HAlford today. Car still refused to start. I hope to receive the LEXIA next week and see if I can update the BSI software without virginisation. or at worst clear all fault codes and see if that can removes the bridge between the ECU, BSI and immobiliser. 'Will post any update later.

Hi All, Thanks for the help. I fixed the BSI back this afternoon. Then, battery is down and have to be recharged again. Then I performed BSI resetting procedures. I heard the clicks as the BSI seems to be resetting itself . I check the starter motors cables, there is current (using the light bulb) but I am not sure of the voltage if it is up to 12v since I don't have a Voltmeter. Then, I tried to start the car, there is a cracking sound from the motor and It appeared the engine turned but the car did not start. Then two attempts like this drew down the battery to a halt. Everything on the car work (central locking, lights, radio, etc). The trouble maker 12V and cigarette sockets worked perfectly as if nothing happened. I feel like pulling the damn thing out and throw it out of the car window. I just could not believe little thing like that could cause untold hardship. A great punishment. If I am lucky to get out of this, I will have them permanently refused or cellotaped. I will be going out right now to see if I can get a new battery since it seems the battery is bad. I don't know precise time the battery was bought but I have used the car now for over a year after buying it. I will keep the forum informed of the update.

Ok. I will check that later today and get back to this forum. Thanks.

Yes KFK that was what happen. Exactly the way you described it. Everything just went wonky as if a high voltage was drawn. The starter motor never turn the engine. Thanks
