    Hi Everyone,

    I was facing low millage problem since Mar-18 with my Toyota AQUA G 2014 so decided to check the battery status on Techstream software with VCX -Nano. Below is the Image of its ECU Menu

    and Health Check Completion Results

    2 Questions
    1. The Device did not detect any HV Battery. It is showing the Hybrid Control but no any Battery Blocks?
    Please Help in this regard how can I see the HV Battery to check its Status and Life.
    2. Hybrid Control is Showing a DTC does this need to be resolved or leave it as it is?

    Regards.

    Some questions:

    • What issues were you having with your Prius?
    • Did you investigate your Prius when the car was in “ready”, “ig-on” or “acc” mode?
    • Did the hybrid control screen show any data?
    Keep us posted .

    Thanks for the reply below are the answers to your Queries

    Ans to Q # 1:- My Toyota Aqua started giving 18~19km/l since March-18. It was giving 21~23km/l before. Below are some precautions I always take while driving Hybrid
    1. Oil - 0W-20 (Only 4000 Km run till yet)
    2.a. Tyre - 175/65R15
    2.b. Tyre Pressure - 33 Front 31 Rear

    3. Altron X Petrol (RON-95~97)

    4. car do convert on EV and Hybrid battery do charge. In my Area the Speed restriction is of 45Km/h, so mostly have to be light foot and on Battery in any case.

    5. Air Filter lastly was cleaned with air pressure on 20th March 2018 (Only 600 Km run till then). Planning to change with Oil after 6000~6500 Km running.

    Ans to Q # 2: - I investigated the car in Ready Mode

    Ans to Q # 3:- Today found the tab to check the HV Battery Below is the data it has collected
    HV Battery.png

    I am concerned for the Battery charging and discharging

    Any help will be Appreciated.

    Thanks

    Dr Hybrid (Formerly Dr Prius) is a handy Android App for checking the HV battery. Simple to use and very inexpensive. Just needs a bluetooth OBD2 adapter...

    Based on the Techstream screen shot, the blocks looked well balanced:).

    The P3000 is a generic code and there would be a sub code ;).

    Some additional questions:
    • Have you looked at the hv battery fan and is it clean?
    • Any history of water entering the Prius?
    • Any rodent issues?
    Since you’ve it t chatream up and running, I’d look a little deeper into the P3000 code ;).

    Keep us posted (y).

    Thanks for the support.
    The P3000 was removed and there was no any other sub code. Below are the answers

    1. Battery fan is Clean, was checked with last service on 20th March 2018 (Only 800 Km run till then)
    2 & 3. As I bought this car 2nd hand so not sure if there were any problems with last Owner,

    can you suggest any good App that can run with VCX nano via Wifi.

    No suggestions on a WiFi enabled setup:(.

    I run a J2534 Mini vci setup paired to a seasoned 20 year old laptop. Running Techstream is its only purpose in life anymore :).

    Are you experiencing any drive ability issues and have any codes returned?

    Best way to ensure the battery stays healthy is to keep it cool (park in the shade, use the AC, etc);).

    Keep us posted (y).

    No I am not facing any other issues, just low millage, which it self is a big issue.

    Thinking to get oil and filters get changed earlier then, to see the impact

    Thanks for the support.

    How many miles on your Prius?

    Have you considered a Prolong setup from Hybrid Automotive? If concerned about your hv battery, that’s one way to maintain it;).

    I have one that I share out here with another member and loan it out to those in need once they install a harness:).

    Good luck and keep us posted (y).

    What I am asking for is actual miles driven, not the fuel consumption ;).

    The Prolong equipment is something Hybrid Automotive sells as a way to preventatively maintain your hybrid battery :).

    I have a harness installed on our 2010 and perform this every smorning often;).

    Keep us posted (y).

    If the mileage is the only issue; I suggest that you start using RON 91 petrol.
    Atkin cycle engine dont need high octane.

    Secondly pls share if you use the air conditioner full time or partially.

    The petrol in Pakistan is not of that quality. I use to get my car fill up from PSO Altron X, till April.

    In May I got it filled from Hasco High Octane.

    I have noticed that the car when runs in peak hot timing reduces the mileage rapidly,

    I keep the A/C on all the time but the temperature is maintained between 26~27C.

    So what exactly is the issue you are facing.
    As regards to milage it will variate as the ambient temperature climbs. Getting stuck in traffic also effects the milage.
    Try driving carefree and keep speed around 50 ~70 km/hr.

    Which brand of Air & Oil filters are you using.

    There are no codes. So all is good

    Got it,
    Understood the higher the outside temperature the lower the battery performance.
    This is the issue I was facing.
    My daily travel is 50~60 Km, but the route is full of traffic, and when I have to travel in hot peak timing the mileage reduces.

    Thanks for the help.

    The same will happen when the weather is cold, too.

    Understand that as well.

    the weather in Karachi is mostly hot, it does not get that cold, so my average in Winter was about 23
