kpro v3 flashing red Led, can't upload/erase, doesnt show ignition on

Post by solosaniok »

Hi
I have an issue with kpro v3 that was perfectly working till yesterday when I tried to upload some calibration updates.

Acura RSX type s 2006
Board kpro v3 Serial Nr 14102
Latest Kmanager 4.5 1.0 build 2419
ECU 37820-PRB-A04 serial 2068-302782 0H22
Car is stock beside some intake/exhaust bolt on bits.
The ecu was bought from a friend that got it oficially with installed kpro board.

Issue: the ecu was working fine for a long time in this car, while uploading some updates to the calibration in the ecu an error occured, unfortunately can't remeber what exactly it was.
I tried re-uploading the calibration and I couldn't because the upload option is not active, only the information tab (screenshot bellow) which shows that some hardware tests failed.
Only the D1 led is flashing red when I connect the usb cable, the kmanager states that the board is online but Ignition is reported as offline even if I switch it on.
The ecu/board doesn look to have any burned elements, everything looks clean. The car wont prime the fuel pump even if starter is spinning it.
I tried the car's stock ecu and the engine started imediatelly.

Please help to diagnose the issue, the car and board is located in europe so shipping the board/ecu for diagnostics is an issue, but can find a good electronics service for any diagnotics needed.

Is the Adapter harness installed and plugged in completely?

Unplug the USB from the ECU, and unplug the ECU from the vehicle, then plug it back in and see if it will allow you to erase the ECU from the online Tools menu.

Yes, the adapter is plugged completly.

Tried connecting the ECU unplugged from the harness and all the Tools options are all gray and I can't select any of them to erase the ECU.

You have to plug everything back in and have the ignition on before trying to erase.

Before starting the topic I tried switching the ignition on before connecting the usb to the board and same was there, I also unplugged the ECU from harness and plugged it in back.
Tools were inactive and ignition as off even if it was on.

Just wondering if this issue ever got solved and if it did what was the outcome? I've got pretty much exactly the same issue.

It was not.
It was trashed since shipping it out from Europe to USA and back + reapairs etc, was easier to buy another one localy.
