Separate names with a comma.
It looks like the logic for the PWM is negative going, such that +5V at S is the off state, and 0V is the on state. That would make sense of your...
Have you cleaned the battery cooling fan? That would be the first thing to check. Make sure there is plenty of air flow through the system. What...
Given that the video linked above shows the tech using a logic pulser to detect the PWM waveform, and is thus voltage driven rather than current...
That white wire "S" on pin 2 of the controller is the pulse width signal. It will be a square wave of varying duty cycle. So your DVM will measure...
IMHO the spec for the tension is rather high, which could lead to excessive pump bearing wear. I backed mine way off with no problem. The pump...
And throws battery temperature as well into the mix, if I am not mistaken.
The "replace wiring harness" recommendation is what dealerships say when they don't know where a problem is, much less how to fix it, and they...
The mini VCI will give you the internal resistances of all the modules directly. You might want to have someone drive a bit while you watch the...
Also, since your VSC light is on, there should be a code set which can be obtained by getting the blink codes: Traction Control Alarm Malfunction...
As always here on PC, the first step is to check the state of your 12V battery. Entering Maintenance Mode (aka 12V Battery Check) without...
Clearly, fuel is still much too cheap where you are.
No, the definition of a series connection is that all modules get exactly the same current flow. Now it is true that the modules in the center of...
The symptoms of charge level rapidly increasing and decreasing, battery hot, and the codes you report all point to HV battery failure. All the...
The fact that the cabin heat is delayed sounds like the system may not be properly purged of air. This is notoriously difficult to do with the...
What happens when you come to a complete stop? Does the ICE shut off promptly? It happens that shops will discharge the 12V battery by leaving...
A shorted cell in the 12V battery can cause your issues. If the battery is not able to reach full charge, then the little converter portion of the...
A little practice with 40+ psi in the tires, and you will get better than 44 mpg.
It may be possible to just lift the inverter out of the way: Spring maintenance Not sure, but a time saver if so.
I understand about the safety issue. In the Prius, there are three modes for the brakes to work. There is first regeneration, then the assisted...
