After you get that new meter, check the 12V battery too. There are threads on this forum on testing modes and thresholds. A small drop in mpg is...
See if any auto parts stores in your area will read the codes for free (assuming that the check engine light (looks like an engine in profile) is...
You can use a wiring diagram (there's one in the Library section of this forum) to test the button unit you bought. It's a resistor matrix, only...
Have you tried opening the hatch with the charger connected? The charger might support the voltage enough for that to happen. Do you own a...
If product warranty is any indication of expected service life, I'd say six years on a lead acid car battery is pretty much it. If you need...
If you start seeing rapid and wide swings in the charge, coupled with the cooling fan running (vent in the rear seat), it's time to start...
This is my guess. You say the noise was happening as you approached the car, and before you turned it on? Normally this pump turns on every...
Those sound like normal readings. When the car is in "ready" mode, the inverter is charging the battery at up to 14 Volts. Your DMM might be...
12.2 V is not so great, less than 50% SOC for an AGM battery. 12.8 V is 100%, 11.8 V is 0%. Was that with no load (push start button once)?...
Agreed, find out if the mechanic can read the Prius ABS diagnostic codes. It may take a specific scanner. And working on the hydraulic system...
I could not read actual block voltage or resistance values in the spreadsheet, just formulas with variables. All Toyota will do is use Techstream...
There are some good internet resource on glass repair, with illustrations. Google it. Chips are usually okay to leave, but cracks need to get...
Presumably you took the car to the mechanic to fix something. What was it, and did it get fixed?
It sounds like it's braking-related, since you said you feel a pulse in the pedal and the noise only happens when braking. I don't know how that...
How long does it make the noise? The CHRS pump always runs when the car is powered off, for 10 seconds or so. (It also runs at every cold...
The "warranty enhancement" you refer to is actually still in effect for some. It's good for nine years from in-service date. Some '09 models are...
It's not very hard to remove the dash panels around the steering column. Google that. With components exposed, it would be easier to identify...
Not all new 12V batteries are perfect. Have you checked the voltage? It should be easy enough to rule out the SKS (smart key) by just turning it...
You're due for plugs, transaxle oil, and coolant if you haven't done that. Change the PCV valve when you do the plugs, it's cheap and it's right...
Is the morning noise continuous? How long does it last? No warning lights on the dash? How many miles on the car? What kind of maintenance?...
