    Hello!

    Bought my 2010 Prius with some issues, most of which are now fixed.

    The remaining issue is the mentioned A/C error code: B1498 A/C Communication malfunction (A/C inverter local)

    Does anyone know what part this is, and the OEM part number? Where is it located in the car?

    Previous owner claimed it was some error with the A/C Control unit.

    Thanks for all the help

    Regards
    Nicholas

    Here are the possible issues causing B1498. If you are serious about resolving this issue I suggest you subscribe to the Toyota Europe techinfo site:

    You will also need Mini VCI and a digital multimeter.
    1. Harness or connector between power management control ECU, compressor with motor assembly and body ground
    2. Power management control ECU
    3. Compressor with motor assembly
    4. No. 2 engine wire (harness or connector between compressor with motor assembly and inverter with converter assembly)
    5. Electric vehicle fuse
    6. CAN communication system
    7. Hybrid control system

    I know this thread is old but were you ever able to resolve your issue? I had my engine replaced recently and I'm getting this code now.
