Daewoo Espero immo problem

[hjulet]

hello. I have problem with Daewoo Espero 1997, 1.5 16v . Engine not start, i read fault: 53- ECM (problem with immo) Please help me , where is a problem? I check wiring, supply is ok in immo box, coil resistance is 14,5ohm, -whether the correct value??? please help me. Thanks

Does car have spark ? If not , unplug 4 pin plug on distributor. Do you now have spark ? If yes use this file

[hjulet]

So the car has spark. Car does not have control of the injectors.

I measured the voltage on the cable that goes from immo box to the ECU, and when the key is in ACC position for a while showing a 0.7-0.8 V disappears in a moment, but I do not know on what basis this immo works and what should give a signal to ECU ..(?)


Voltage at Immo box on one cable on the second 12v when the ignition key to acc position appears 12V, Ground, it is, so what could be the problem ??????????

It appears your vehilce has been immobilized, do you have a spare key? try that if its doesn't work then i suggest replace or reflash the immo.

What immo coil resistance correct?? I read that it may be defective coil. What do you think?

[Zaveruha]

I think you have good coil. You could do diag for immobox.

[hjulet]

And how can you do? I read out the fault : 53, the ALDL jumper pins A & B.

You need diagnostic device. Also you may do immooff.

[hjulet]

whether it is a Motorolla immo HC11F1?

[Zaveruha]

whether it is a Motorolla immo HC11F1?

No, it should be HC05b.

[hjulet]

Do you have a clean dump?

[Zaveruha]

What are you mean? Are you want immooff?

[hjulet]

Yes, I have Immo off :)

nr ecu : 16199550 TR

[Zaveruha]

For immooff you could read and then UV erase 27c256. And then write dump without immo. I have some dumps but i dont remember which is right. What is the letters on your 27c256 chip?

[ecufix]

Immo off only needed if no spark .If 4 pin plug on distributor unplugged and then spark yes need immo off . If 4 pin plug connected and spark and no injector sig check wiring or injector driver in ecu.

The spark is all the time. The problem is this-when trying tostart the the engine - control fades Injectors - I did the LED test and mryga for 4 seconds and goes out :( enginebehaves adequately or fires for 3 seconds and goes out .... already checked the cables and even the second set :ECU , immobox with key and coil and the effect is the same, and extinguishes fires. ... help please

You have problem with immo. Post type of your ECU(writed on 27c256 chip)

[hjulet]

but why the second set) and immobox ECU and key and coil), is the same problem? and efficient set from another car ...

May be you have problem with ECU to immo box conections or some suplly voltage.

[hjulet]

connections ECU to immobox, immobox to coil is OK, supllz voltage is OK,

I have a suspicion CKP Crankshaft position sensor but resistance is ok - 700ohms

What do you say about this?

[hjulet]

sukcess success success!! turned out that the cable connecting the coil were immo box, sometimes not connected. turned out to be also the principle of operation Immo: immo gives 4.95V to ECU: D: D: D
