Mg1/mg2 renamed?

I've heard nothing of an official change.
Based on how the respective M/G are used most of the time. I'd same M/G1 is the generator, and M/G2 the motor.

 

Pretty sure they still both do the same thing. They've been redesigned and moved around is all.

 

I was thinking the software vendor did not know the Prius MG1 & MG2 terminology.

 

The parameter names in the app, with “Generator” or “Motor” rather than “MG1” or “MG2,” appear to be the same as those used in Toyota’s Techstream diagnostic software. For example, “Generator Inverter Calculated Temperature just after IG ON,” from @Yippeekyaa's second screen shot, appears in the Hybrid Control Data List in Techstream with exactly the same spelling and capitalization.

Toyota’s Repair Manual and New Car Features books still refer to the two※ synchronous machines in the fourth-generation Prius as the “Motor Generator No. 1 (MG1),” “Generator (MG1),” or “MG1” and “Motor Generator No. 2 (MG2),” “Motor (MG2),” or “MG2.”

※ Except Prius with E-Four (ZVW55; Japan only), which also has “MGR (Motor Generator Rear).”

 

What is the app name? Inquiring minds want to know...
Does it just display data or can you set things like the reverse alert?

 

@Tideland Prius may want to add this information to the PC Glossary. Perhaps Toyota is moving away from the MG1 / MG2 naming.

 

So, if we have a Generator, how long until somebody wants to "upgrade" from a Generator to an Alternator?
I see discussions like that on older tractor forums.

 

With their powers combined, they become MG3!

 

I guess then we have motor + generator just to confuse things further.

 

Toyota’s Repair Manual explains each parameter in the Data List/Active Test section for the relevant system.

No, the boost converter is part of the inverter with converter assembly in the hybrid system. As Toyota’s New Car Features book explains, it “Boosts the HV battery nominal voltage of DC 201.6 V / DC 207.2 V up to a maximum voltage of DC 600 V and vice versa (steps down DC 600 V to DC 201.6 V / DC 207.2 V).”

From the New Car Features book: “The leak detection circuit constantly monitors that the insulation resistance between high-voltage circuits and body ground is maintained. [...] The leak detection circuit has an AC source and causes a small amount of AC to flow to the high-voltage circuit (positive and negative). The more insulation resistance decreases, the more voltage steps down at the detection resistor and the lower the waves of AC. The insulation resistance value is detected based on the amplitude of AC waves.”

In the parameter names, “short wave” refers to the AC source in the leak detection circuit; “MG Inv,” motor and generator inverter; “A/C Inv,” air conditioning inverter; and “SMR,” system main relays.

The Repair Manual section for DTC P0AA649, “Hybrid/EV Battery Voltage System Insulation Resistance Decreased,” and its unsavory associates, P1C7C49, P1C7D49, P1C7E49, and P1C7F49, has more about this.

MG1 and MG2 are three-phase machines, and Toyota uses the letters U, V, and W to identify the three phases.

 

I purchased that app already, but I am having troubles finding the right PID for the backup beeps. I was wondering if you had any resources to point me in the right direction. I learned Charista has it built in, but that's another 20 bucks. I'll spend it if I have to, but since I already have another, seemingly capable app, I'd like to just figure that out.
I found another page using Torque, but I think that's specifically using Android (which I don't have). But that one was cool because you can send different terminal instructions to do things like change the beep to One beep instead of continuous, or turn it off completely.
I'd love some help if you could.

 

If you're about to buy a Gen 4, insist on the dealer removing the backup beeps before delivery - they should do it for free.

 

No, I bought a used 2011. I already used the ODB Fusion app, so I was just trying to figure out how to get the PID for it.
