    Is a automated process ? As I'm looking at the techstream software but cannot see such setting in the menus.

    Yes ,not servicing at Toyota anymore , nearly 200k on the clock , trying to find what can give error code p0a7f but Toyota got no idea what can be ,they suggested to check HV fan and told me they can only do the health check after about 400 miles from when the error as been cleared ,the error keeps popping up just when I want to take to Toyota for the check ,so if I can do it myself would help if is a automated test. 1485195506512.jpg 1485195512620.jpg

    Have you cleaned that fan and you're still getting the code?

    Even though that fan is kinda ugh, definitely needs a cleaning, it's better than the Luscious Garage horror story pic's. Run a duster wand through all the ductwork too. Then compressed air everything.

    we don't have the health check here, so idk what's involved. i don't think there is an automated program in tech stream. the most i recall reading about is putting a load on the battery and looking at the variance in cell voltages.

    The Toyota guy showed me a health check print out that failed the test because the errors codes that were cleared previously did still showing and it needed to drive about 400 miles without showing any errors so that the health check could complete the test .....
    This is the third time I asked....I got the same answer...,so I believe there must be a software or a setting on techstream that will run the test and then make a print out of the outcome.! Got to look for this printout between my papers ...I had one done on last time I serviced the car at Toyota
