    Hello to all forum users. I would like to present the fault codes maybe someone had the same or similar problem. It is P1349 and p1351:

    P1349 - Permanent defect. Preheater relay circuit. Short to + or open
    P1351 - permanent defect. Preheat relay circuit. Relay activated. candles not powered.

    I will add that I connected another relay and there is the same error and the second ECU with the same numbers is also the same error.
    Thank you in advance.

    Check the power supply to the relay. And the candles themselves. Candle wire - relay.

    The candles were changed a year ago and everything Ok the power supply goes to the relay but it doesn't heat the candles. Probably somewhere the harness is frayed or some wire is broken. If I can fix it, I will try to describe what was wrong.

    I consider the topic closed. On a walking engine I screwed on these two separate wires, the cube was plugged in and the error disappeared for so. Thank you for your help, sir.
