I now must use the key to open the door but the car operates fine otherwise, except dash shows that the boot is open since the accident. .. which of course it isn't. How could I repair that?

Please tell me what the black bolt in the middle of the cover ecu? air flow or what this....

I found an exploded capacitor in mine. At this point, I have to guess it was one of two used as smoothing capacitors, mabe even a backup. Someone had replaced two of them and reversed polarity on one. It was a low voltage cap. As it didnt affect anything, my guess is it might be for OBD2 power supply or something none critical.

i do have a question, when you are simulating cam and crank signals, i know that before the pcm will work the injectors and ignition, it will be looking for specific patterns of the crank and cam, and how they are synced. how are you accomplishing this/ THANK YOU.

@saudautomation

Жыл бұрын

Hi, Your point is very valid and correct, in fact what I think in this type of simulation the ECU hardware and program is just reacting to the input signal and not genarating timed output, it keeps trying to adjust the output all the time , this semulation signal is at low RPM and the ECU is not fully functioning and in fact this helping us just to get the output and check the ECU respond, not only that but we can get the injector and ignition output only by providing the crank signal alone without cam signal and also it is giving the output eventhogh the immobilizer is not disabled, I know if you use a semulation device like MST 9000 the ECU generates more timed output signal.

You are very welcome, There is different ways to deal with this, but first step don't forget to try start by spare key if you have. 1-Try to reset the ECU, by erasing the eeprom data you will need at least some eeprom programmer to do this, then after that you need to register the key again by following key registration procedures you can serch for the procedure forms the web based on your car modle. 2-If you suspect the ECU is defictive, then you can try to clone the eeprom on new ECU, just by removing the eeprom (this is ic with 8 pins) from faulty ECU and use it to replace the same eeprom at new ECU. 3- try to do immobilizer off or delete but you will need programmer and some computer application to do this. All the best

Hi, Depending on the failure mode and fault different troubleshooting approach and technique can be flawed, I for example the complete unit is dead and not responding then I can start to check the supply voltage and the healthness of main microcontroller, but if two or three outputs are not working then I check what is the common component meeting them and replace if required, If one output is no working I start tracing from that output pin going down I keep checking all the components on the way until I get the faulty one. Some test I need to keep the unit off powered and sometime it should be powered on depending.

Hi, Thanks for the good point. The inputs provided in the diagram was example of basic parameters to ECU as simplified schetch only. Indeed you are right immobilizer system is one of inputs to ECU this can be external transponder ECU in some designs or integrated in the ECU, if non authorized key used then received security code will mismatch to the one saved in ECU eeprom and engine won't start. In fact there is other inputs also like status of gear if neutral or park, brake padle pressed status, IGF for ignition feedback in some cases.

I put it in today, and it ran pretty well (they both use inline Fuel Injection pumps, so I don't have to worry about 6 vs 4 cylinders). The boards and pinout are the same, but with the replacement ECM in, it runs at about twice the speed it should at idle (I think the gear that the speed sensor senses is a different size). I don't have Schematics, but I do have all the pinout and the functions of each connector pin. Could I correspond with you to see if I could find a way to solve my problem? Perhaps by email?

Hi, Good and important question, In fact most ECU circuit implement diode protection at power input, this with different arengment, sometimes the diode is just connected in reverse so anode to ground therfore if battery power was reversed heavy current pass across the diode and fuse blow. Sometimes the diode is connected forward direction to just block the reverse power also some circuits implements 2 back to back diodes, you can see sometimes mosfet is used to block the reverse power. Anyway if the fuse was slow to blow the reverse power will negtivly afect the ECU circuit, diodes and electric capacitors plus regulator might fail but if the reverse voltage spike reaches the microcontroller or other IC's then for sure microcontroller chip cannot tolerate that most of time and just fail.

Depending on the failure , is it the ECU not responding and failed totally, at least are you hearing the fuel pump starting after ignition on this can be one indication of ECU status , are you getting the 12 volt reaching the ECU normal after the power reversing, is it blowing the fuse, the protection diode will be close to the 12 B+ input pin.
