    Can you do a reset/power the car on and off? If that doesn't work try checking the fuses and contact Tesla Service if you continue having trouble.

    Someone else here may also have additional advice that might help.

    Thanks! If you'd be able to take some pictures many thanks in advance too. I might be looking at a pump replacement myself as I discovered a small leakage @ the pump. Not bad, but it's there.

    Yes^^ Thanks in advance for taking pictures. Try to find out if the coolant heater is integral with the pump, or if it's a separate part. If it's separate, see if you can take some pics of that, too. Thanks:smile:

    The next isue is to lift roadster
    But with a jack and lift take of the rear wheels and lift in the front lifting points and under the coilovers

    IMGP6802.JPG
    IMGP6803.JPG

    I took of the bottom plate under the battry
    But there was no pumps

    After some look i fund the hoses and the goes up under the right side front part of the rear fender wall

    IMGP6804.JPG
    IMGP6805.JPG

    The pump is placed in serie and the heater is place after the pumps


    I disconect the sockets an check the voltage in the contact
    The volage was only 1V not 12V i test to put in the new pumps on the wires and they didn't start ether
    Can some help me with a electrical diagram were the supply come from?

    And last a photo of uncommon combination of cars

    IMGP6810.JPG

    I took a OHM meter and messure the restance of the new pump and was in Mohm class that count up and out and i flip the poles and the did the same

    I have check the signal out to the pumps and messure only 1V

    Are you measuring when the pump is supposed to be enabled?

    Otherwise the 1 Volt could be a signal from the PCM to search for the pump being connected, and it would never enable output to the DC-motor without sensing the appropriate resistance from the Pump itself.

    It should be a two pole connector, with one being the feed (12 Volts) and the other side grounded by the PCM when the car enables the pump.

    I got a coolant error message. The service center looked into it and they said the message was popping up because the pump was drawing less current than it was supposed to. This is either an indication that the coolant is very low (which it wasn't) or the internals of the pump are wearing out. Their quote to replace it was $684.56.

    PUMP-ESS COOLANT PCA12 (2004503) $373.73
    Labor $280
    Tax $30.83

    The pump price is a little outrageous if the pump is the bosch pump that I can buy on Amazon for less than $100.

    I talked to the technician about it. He said it was really easy to replace because it just involved two hoses, an electrical connector and had reasonable access.

    Here are some pics of the pump and heater. The first 3 are 2.0/2.5. The last 3 are from a 1.5 which only has one pump.

    Have you disconnected the 12v battery and pulled the ESS service disconnect, then plug it all back in?
