Your conclusion may well be correct. Now there's a chance: The car that gave up the ECM box, which is now a replacement, the BeCM and lock and key are available from that car. Then they would possibly be compatible with each other...

I read that the success of the ECM tutorial can fail due to a small deviation. I noticed that Nanocom had changed the Vin number of the replacement ECM to the same as the old ECM box. Is this the small error, should this field be reset?

Screenshot: This is again Google's fault, I've taken a screenshot of what you posted, I haven't posted a screenshot. I'm sorry again.

Ok, I went to test. First: both boxes are ERR-6645. Old Ecu tune ID: 9605 Replacement tune ID: 9625. The old one has Security mode YES, the replacement one has NO. I did the suggested lesson 5 times, always the result was NO

Thanks Again, I took a screenshot of the instruction and printed it out. Go check it out. I think it had a "tuneup" and a four-digit number, as well as other readings. I can pick them up from both.

I have looked at the wiring diagrams. My eyes caught the ECM connector, (C507, red 36 pin) pin 26, black wire, BeCM, Engine Immobilization input. The color black would indicate grounding. Could it be as simple as that, does the BeCM connect or disconnect this line to block the start???

That's what I think too, there are stickers on that ECM, if you open it, the warranty ends. Well, it's over anyway (10 years). Tell me if that code p0605 is dangerous, (Nanocom told a couple of answers above).

I have tried three times to teach the new ECM as instructed. Failed, Failed to Start. When I put the old ECM in place, and do nothing else, the car starts fine. When I look at its information, the field for the vin number is empty, there is no other initial information either...

Immobilization code 65535, EKA---, FOB---, Eka Disabled, Alarm Enabled, Immobilizer enabled. Learn mode has been activated. I received such information. Spins but won't start.

Ok, I'll give it a try. I will return to the channel. Thank you!!!

I feel very stupid, does that code I'm looking for in BeCm mode have to be written somewhere, or will the new ECM pick it up from there?

Can I ask again, I haven't done this before. So: Take off the battery shoes. Remove the ECM. Install a replacement ECM. Ability battery terminals. Plug in the Nanocom, and let's turn on the ignition switch. Do not start. Let's select learning mode from Nanocom's menu and accept it. Turn off the...

Hi again! Now I have tested with Nanocom, and got the values: Fault code P0605 Internal control module read only me (ROM) error. Loop status Cl. Use 02. Pre cat o2 sensor (V) 0.05 to 5.85. Fuel trim long term (%) -160.00. Fuel trim short term. - 12.65 - 16.25. Fuel Temp - 255.00. Fuel...

Yes, if only I could understand this with Google Translate. So the readings come from the OBD tester Icarsoft LR V2.0. So I haven't gotten them anywhere else. I used a Fluke 365 to measure the resistance of the sensor wires, for which I performed 8 different measurements, whereby each pin of the...

Could you just measure those A or B banks, eg C507, pins 33 and 32, is there positive or negative voltage if you measure the Plus or ground terminal with a Fluke 365. I also have a UNI-T UT81B scope if needed. You cannot connect the meter to all pins, you have to be careful.

If you mean the volts given by Bank A and B, I haven't tried to measure those volts in any way. I think that these wild volts should be interpreted as a destroyed part inside some bigger microcircuit, and then you get an incorrect reading. I am even more convinced, the ECM declares itself thus...

So, those volts are not really there, I suspect that the ECM has failed and is running some maximum values for some reason, which I am not the right person to answer. This is so utopian, but I get these values now, every time. The obd tester doesn't see such volts, apparently it just tells what...

My multimeter for car use is the Fluke 365, true rms clamp meter. I measured again with obd scanner, Icar, Ox sensors disconnected. Results: Bank A Ox 316.25V varies. Bank B 229.90V varies. Ox heater 15.06 Ox sensor heater 46592%. Ox sensor configuration, No Sure. Idle reference speed 48130. Ox...

Yes, I feel the same way about the abilities of that Icar tester. Another thought is that the ECM is damaged, which the home p0605 has already determined, and this, along with the outdated O2 sensors, is possibly running something of a loop not knowing what to do with the readings. If so, Icar...

Thanks for the answers! I'm testing without O2 sensors. To clarify or confuse, the O2 values when testing before wandered recklessly, changing from one reading to another within a second, between 1.5 and 320.52V. The wires are fine from the ECM to the O2 connectors, resistance values 0.1ohm...
