    hello I have a question about drivers in peugotach. and exactly I have a peugot 207 1.4 driver in it j34p valeo guest tried to remove immo in it but burned the pcb board reseystorki next to the memory 95160 lost because he desoldered before that the car normally burned only a stone from the immobilajzer got lost and I did not have the second keys with me and I was far from home and I already have an immo key. but the driver is damaged, I found the second driver at the auction, the same numbers sw and hw, I have access to the pp2000 interface, just insert the driver and use pp2000 to check if you need to do some memory, thanks for the information, best regards

    Solder the old EEPROM (95160) to the new controller. Rather, it's the fastest way.
    You will not code the key on pp2000 alone, you must have the PIN code of the new controller and an uncoded key (transponder).

    I did it, now it is spinning, but the car does not start the error ecu p0602 popped out or I have to somehow rip the ecu with bsi .. About immo in any subassembly there are no errors, i.e. good memory from immo otherwise it would have crashed some errors. There is nothing to do in bsi now THANKS for the info

    You need to have the pin code from the car and re-encode the immo with the key and the ecu using pp2000.

    I have already pulled the code from bsi because I did not have and this coding is difficult //?

    The coding itself is not difficult. There's a corresponding button in pp2000 in the "encoding" program window or something like that, I don't remember exactly. After entering it, it will ask you for a PIN and you continue the procedure.

    Hello and so far, I still have error p0602, I tried pp2000 to install a new driver, but pp2000 says that the driver is not on the list, it is not possible to instruct the code from immo d9bry because the key programming is successful I do not know what to do next, do you have?

    Hello
    Nobody here will lead you by the hand.
    You can solder the Eeprom, read the batch and use "calca" to extract the PIN.
    And the PP2000 when connected tells you what's wrong with the system. Make a set. diagnostics of all modules, in particular BSI.

    Well, I have the basics of electronics, but when it comes to diagnostics and car coding, it is very thin for me, so I ask on the forum where to look for what to check today I will check THANKS for guidance, best regards

    OK, but something's wrong here, why did you delete immo?
    After all, it is better and cheaper to add the key, now you have to add the key and calculator and clean the BSI. Rather no chance, as usual, as the repair started from the d .... side.

    For this BSI encoding and if you do not have data, it will be fragile. Half won't work and then you start asking? Why does the air conditioning not work, and the wipers worked.
    If you already have a PIN, put in the immo eeprom and code.

    I would buy a starter kit with what you have.

Topic summary

✨ The discussion revolves around the challenges faced in replacing the J34P Valeo driver in a Peugeot 207 1.4 after PCB damage caused by an attempted immobilizer removal. The user successfully soldered the EEPROM (95160) from the old controller to a new one but encountered an ECU error (P0602) and issues with key programming using the PP2000 interface. Participants advised on the necessity of having the PIN code for the new controller and re-encoding the immobilizer with the key. They also highlighted the importance of performing diagnostics on the BSI module and suggested that the user should have added a key instead of attempting to remove the immobilizer. The conversation emphasizes the complexity of car coding and the need for proper diagnostics to resolve the issues.

FAQ

TL;DR: For a Peugeot 207 1.4 with J34P, you need 1 PIN code and PP2000 to re-code; “The coding itself is not difficult.” [Elektroda, adamus202, post #16947944]

Why it matters: This FAQ helps DIYers fix no-starts and P0602 after ECU/PCB damage using PP2000 and the 95160 EEPROM.

Quick Facts

How do I replace a J34P Valeo ECU after PCB damage?

Use a matching J34P unit, then transfer the original 95160 EEPROM to it. This preserves immobilizer data and speeds recovery. If you skip the EEPROM transfer, you must re-pair ECU, key, and BSI via PP2000 with the correct PIN. [Elektroda, adamus202, post #16937230]

What does DTC P0602 mean after an ECU swap on a 207 1.4?

In this context, P0602 shows up when the replacement ECU isn’t fully configured. The starter will spin, but the engine won’t start. Finish immobilizer pairing and module coding in PP2000 to clear the condition. [Elektroda, piotremilianczyk, post #16947417]

Can I program a new key with PP2000 alone?

No. You need the vehicle’s PIN and an uncoded transponder. Without both, PP2000 won’t complete key programming or immobilizer pairing. “Solder the old EEPROM to the new controller” remains the fastest workaround if you have it. [Elektroda, adamus202, post #16937230]

How do I retrieve the PIN code needed by PP2000?

Read the ECU/BSI EEPROM dump and extract the PIN with a calculator tool (“calca”). After that, use PP2000 to perform immobilizer coding across ECU, BSI, and key. [Elektroda, CAR pass, post #16950885]

Is PP2000 immobilizer coding difficult?

It’s straightforward once you have the PIN. In PP2000, open the coding/encoding screen, enter the PIN, and follow prompts. “The coding itself is not difficult.” [Elektroda, adamus202, post #16947944]

Do I need to pair the ECU with the BSI on a J34P swap?

Yes. Obtain the car’s PIN, then re-encode the immobilizer to link the ECU, BSI, and keys using PP2000. Skipping this step causes no-start conditions. [Elektroda, adamus202, post #16947515]

PP2000 says the driver isn’t on the list—what should I do?

This happens with certain replacement ECUs. Verify the exact ECU family selection and complete coding. If PP2000 still can’t list it, return to EEPROM transfer and immobilizer pairing. [Elektroda, piotremilianczyk, post #16950066]

Where should I start diagnostics before coding?

Run a complete vehicle scan and pay special attention to BSI fault lists. Fix underlying module errors first, then proceed to key and ECU coding. [Elektroda, CAR pass, post #16950885]

What is the 95160 EEPROM and why is it important here?

It’s a serial EEPROM that stores immobilizer data used by the ECU/BSI. Moving the original 95160 to the donor ECU preserves pairing and speeds the fix. [Elektroda, CAR pass, post #16952004]

Quick 3-step: how do I perform the immobilizer recode in PP2000?

  1. Open PP2000 coding and select immobilizer/encoding.
  2. Enter the vehicle PIN when prompted.
  3. Follow prompts to pair ECU, BSI, and key, then cycle ignition. This 3-step sequence resolves many P0602 no-starts. [Elektroda, adamus202, post #16947944]

What’s the risk of coding BSI without complete data?

Incorrect BSI configuration can break features like A/C or wipers. Always back up configuration and code with verified parameters to avoid functional loss. [Elektroda, CAR pass, post #16952004]

I lost the original 95160—what now?

You must retrieve the PIN from BSI or available dumps, then code a new or uncoded key and pair the ECU with PP2000. Without the EEPROM, expect extra steps. [Elektroda, piotremilianczyk, post #16937044]

Do keys need to be uncoded for successful pairing?

Yes. PP2000 expects an uncoded transponder when adding a key with the vehicle PIN. Using a pre-coded key blocks the procedure. [Elektroda, adamus202, post #16937230]

Any red flags while troubleshooting a no-start with P0602?

If the engine cranks yet never fires and P0602 persists, return to immobilizer coding. Confirm correct module selection and PIN entry in PP2000. [Elektroda, piotremilianczyk, post #16947417]
