    Hello everyone, I hope you're all doing well I'm new here, I recently bought a 2010 Prius 3 with 240,000 km,

    The car is very comfortable, but after a month of use, I ran into a problem two days ago ,I got a “Check PCS”

    And “Check Hybrid Battery” warning light. I drove home, but the car didn’t have much power.

    I searched online, and someone suggested disconnecting a white cable for 20 minutes. I did that, then

    Reconnected the cable in its fuse box slot next to the engine. Since then, the warning lights for “Check Hybrid

    Battery” and “Warning” have disappeared, and the car drives fine again — but sometimes it feels like the

    Accelerator cuts off briefly.

    Do you think the issue might be with the hybrid battery, or could it be the inverter?

    Also, I noticed that my inverter’s part number is G9200-47190. From what I’ve found online, it seems that this

    Inverter is from a Toyota Auris, not a Prius. I can’t find any 47190 inverters in France, only 47140 ones. Are

    Those the same?

    Thank you very much for your help![​IMG]

    But it's been working fine with this inverter that's installed I believe they're the same . If it swaps and plugs up and wire colors look same as connected etc . It should be a go it was working fine all this time . So I'd think it's ok or was.

    it's worth checking the battery before you run into more serious issues. you will need a scanner like doctor prius: details

    Whenever you get a warning light on the dash, you need to use a scanner to read the trouble codes. Do not clear the trouble codes by disconnecting the 12v battery until you have written down all the trouble codes. The trouble codes will lead you in the right direction to fix the problem.
