Separate names with a comma.
If I recall correctly, you can change the "A/C on with defrost" behavior in the "customize" menu in Techstream. .
Here's a diagram. The relay should close whenever the ignition is "on" or in "ready" mode.[ATTACH] .
Somewhere on the outer CV joint, there's a pinhole leak in the boot. As the wheel spins, grease gets flung all around. Posted via the PriusChat...
So, my understanding of an "all keys lost" scenario is that you need an "OE level" scantool. You go through the procedure as prompted by the tool....
As others have mentioned, measure the voltage drop across each fuse. You need a multimeter that can read down to 0.1mV in the millivolt range. I...
What is the car doing that leads you to replacing the MAF? They do fail but that's pretty rare for Toyota. I want to check power, ground, and...
It comes down to an individual's risk tolerance and circumstances. If you have a brand that works for you, then great. As a shop technician, I...
If you have a capable scantool like Techstream, then use it to check all systems for codes. Some systems will keep "history" codes in memory for...
Some people have reported instances where the aftermarket pump they used worked fine, - until it didn't. Specifically the pump would...
So for your 2009, did replacing the p-con fuse fix all of its problems? Someone is leaving out details somewhere, as I have never seen a fault...
In whatever ECM data that the app can display. There are two values - short term fuel trim (STFT - it's a direct response to the Air-Fuel sensor....
AFAIK, those codes are "internal" to snap-on's programming (hey, I lost comm here) and not really much use for diagnostics. What system are you...
Because it is most likely that the noise is not coming from the inverter pump. When you "start the car" (go to ready), the ECM runs the Coolant...
That code involves one of two signal circuits between the hybrid control ecu and the controller inside the inverter assembly. Having a capable...
Per Chapman's post, point A is the 12V battery (13.2V with your charger). Point B is the transmission control ecu (which showed around 7.4V in...
It could also be something like leaves and dirt blocking the bottom 1/4 of the radiator. The code just indicates that the inverter got "too warm",...
I might want to look at the switch that lets the Body control ecu know that you have opened the door. .
That is the "main" 12V cable that connects the battery to the car. So when you want to power up the car all 12V for everything has to go through...
You need a more capable scantool to check the 15-16 systems on a Gen2 Prius. Here is a thread that reviews several options. The synopsis is post...
I hope you were able to figure out what was going on. FYI, the more capable apps (such as Autel and ThinkDiag) will only work with their own...
