PEUGEOT 308 T9 1.5HDI 2019 NO OBD CONNECTION HELP

[edge77]

Hey guys!

i wonder if someone came across a similar issue!

After flashing dpf off, car did not start, but would crank and do diagnostics.

Returned back to original backup, car started and everything was ok.

My file source send me new file, tried again, car started twice, no errors, all seemed ok, but at 3rd try no more starting, but would crank.

Returned back to original, everything ok again.

3rd files comes up, developer said change bit, flashed to car, no start or crank...damn...

Then i tried Diagbox, can even see vin, or connect to any module...not good.

Flashed back original like before, the result was the same, no start, no connection to any module...

Noticed that car doesnt lock doors anymore, only folds mirrors when pressing key fob

Tried to check evey fuse, bsm, bsi, all good.

Ecu on bench works ok, read and writes perfect.

Car switches on ignition, esp and abs light, battery light, and engine error on screen.

Please help!

Thanks to all.

You should connect with other modules....

car is keyless? do you have second key to try?

[edge77]

Nope, not keyless bro, and no other key i guess
Thanks for reply

[Panathaole]

some official diagnostic tools, connect to others module thru ecu, try to diagnosis the car with other diagnostic tool....

Yes, i tried with autocom, lexia, autel and some others...i have no resistance on can lines or power, just 12v...can lines are dead...ecu can be diagnosed on bench...my guess would be immo active..

[edge77]

Friends. help me out here, is it possible BSI is locked?

[Panathaole]

You should connect with other ecus.....

If you remove the engine ecu, you still can't connect with any other module?

Have you check the obd?

[edge77]

Yes, no can L or can H, just 12v, also no resistance. Ecu reads and diagnoses without problems on bench.

Gonna read BSI and maybe make it virgin?

[chacarita]

The Red Can has 60 ohms of resistance between the pins with ECU and BSI connected, if when you disconnect the computer or the BSI you have to measure 120, because they are connected in series, when both are connected it measures 60 ohm, if you don't have anything I would check the insulation of the cables between themselves, to ground and to + with all the network computers disconnected

Yes, i know, but no, nothing. OBD plug connects directly to BSI.

No ohms between pins, can l or can h. only 12v on OBD Plug

Car was reprogrammmed for DPF OFF as i mentioned, after that no more start or OBD comms.

Dont know what else i can do...i guess BSI locked itself because of immo.

Nobody had similar issues b4?

[chacarita]

giveme the vin number, but you need find why you dont have resistance, letme check wiring with vin number

[edge77]

I've checked pinout, obd plug goes directly to BSI.
BSI and OBD plug get 12v, but no CAN L or CAN H
To remember that's this happened after engine ECU flash for DPF off.
Car doesn't lock doors since this happened, only closes mirrors when pressing key fob.
Before all was working fine with no issues.
I tried to flash engine ECU, eeprom and flash with original backup which made no difference.
I'm guessing Engine ECU IMMO locked BSI for some reason.
Engine ECU works fine on Bench, can read eeprom, read flash, and also diagnose with can lines connected to breakout box.

when you connect with lexia/pp2000 how do bsi and ecu identify?

shud be unlocked, paired (or learned) if you see locked or unpaired you have alot to do.
If you have only locked but bsi has ecu learned try immo off, shud work.

Hey guys!

Car is in eco mode, no crank no start, hence no OBD connection?

How to make car go out of eco mode being and non starter?

I had OBD connection, flashed one MOD file for DPF OFF that did not work, made with swiftec.

So i went back to original, car worked fine, but with DPF errors.

Then i flashed 2nd mod file, car started twice with no errors, but 3rd try no more crank or start.

Flashed back original file again, this time no luck at all, no crank no start, car in eco mode as soon i turn key on, no doors locking, only folding mirrors.

Tried to flash original back again, with BITBOX, with Kess Original, nothing works.

Maybe all the DTCS in ECU that i cant erase, doing this...im lost.

Im able to scan and diagnose ECU on Bench with can lines connected to breakout box, to see a bunch or errors, that i cant erase because is not connected to car.

Reading and writing ECU eeprom and flash also works fine without issues.
