Renault wont start after clicking pressure regulation adaptives

Unread post by Renault2025 »

Hi I'm wondering if anyone can help, long story short, clicked pressure regulation adaptives on a topdon artidiag pro scanner and car won't start. I have error code 00871c rail pressure,voltage outside tolerance limits.
Is there any way to fix this with the topdon tool? Tried disconnecting battery for a couple days, tried touching the battery negative and positive wires together in hopes of ECU resetting but no luck.

Try these with your Topdon Artidiag Pro

Fuel system relearn/reset – Look for rail pressure reset in adaptations.
Prime the fuel pump – Cycle ignition or use the scanner.
Clear DTCs – Then try starting the car.
Check wiring – Ensure fuel pressure sensor connections are secure.
If still no start, dealer-level re-adaptation may be needed.
