ScanGaugeII work on 2010?

Yes, the Block voltages vary with SOC and VB+ so it depends on when I program each block voltage. I would have to have all 14 ready to display to determine the different voltages and the correct scaling. If you get the correct scaling let me know.

OK Thanks

You are exactly right. I did not pick up the 1 being shifted to the left. Let me try that one again.

Why are 6 and 13 treated differently than the other 12 voltages ?

 

I just got back from trying again with the 1 moved to the left for multiply by 256. V06 returned a 1536 which when added to v06 is in line with the other voltages. So, all of the voltages and resistances work as you configured.

 

Each Consecutive frame can only take max. 8 bytes and 1 byte is being used for PCI so only 7 bytes left for data. Each Block Voltage need 2 bytes so there will be cases whereby the Block Voltage will be split into 2 Frames; one at the end of the Frame and the other at the start of the next Frame. 6 and 13 happen to be at the split.

Do you remember I told you that you can make use of the Data List? Under the Measurement Item / Range, there are Min. & Max. value. For e.g. the ZVW35 has Min. 0V & Max. 79.99V. Since 2 bytes range from 0000h ~ FFFFh,

FFFFh / 79.99 = 819.29 is the scaling factor.

Vincent

 

Thanks for explanation.

 

Good deal. Where did you find this in the Data List?

How do you convert the above scaling factor to MTH parameters?

Pretty close to the 820 we came up with. I watched V01 and V08 this morning coming to work. 60 mph on fairly level ground the SOC holds right at 60% and BV+ settles out around 225V. V01 and V08 both settled out at 16.55V with our current scaling factor of 8. This shows about 3% high when multiplied by 14.

I plan to change to V02 and V09 this afternoon on the trip home.

 

In the ZVW35 Repair Manual.

	Column 1	Column 2	Column 3
0	RXF	MTH	Notes
1	02EA85610681	000120010000	XX.X V
2	02EA45610681	1F3FFFFF0000	XX.X V

It looks like both ZVW30 & ZVW35 are using the same scaling.

I thought I had drilled way down in the ZVW30 Repair Manual and could not find the battery module pair voltages nor the resistances. After reading your response I went back and drilled down even further and sure enough found both the battery module pair voltage ranges and resistance ranges. Sorry about that.

I will try these new scaling factors in the morning drive to work.

Thanks again,

Dwight

 

Oops, I'm sorry about the error. It should be multiplied by 10 but I divided by 10.

Vincent

 

Yes, I tried it this morning and received a 0.1. I was going to say that we needed to multiply to move the decimal point.

The other one where you multiplied by 7999 and divided by 65535 worked fine. I watched V03 and V10 this morning and they were both right around the BV+ value when multiplied by 14. So, we definitely have the scaling correct now.

I will try the corrected one above this afternoon and watch two more module voltages this afternoon.

Thanks,

Dwight

 

Your corrected one worked fine this afternoon. Thanks for giving two different ways to configure the RXF and MTH parameters to get the scaling factors correct.

I tried two more of the module pairs this afternoon. I am surprised at how well the different module pairs remain balanced. I have been doing like 1 and 8, 2 and 9, 3 and 10, etc. to get pairs on either end of the battery string. Even then the numbers move up and down with BV+ but never more that 0.1V from one another and then settle out to the same voltage when BV+ settles out on fairly level ground.

Thanks,

Dwight

 

Vincent,

If I want to use the bottom format for the correct scaling for V6 and V13, I also need to multiply by 256. So, 7999 + 256 = 8255 = 203Fh. So I would use 203F in place of 1F3F for the multiply, correct?

Dwight

 

MTH = 1F3Fh / FFFFh * 256
= 7999 / 65535 * 256
= 7999 / (65535 / 256) ; 7999 * 256 will cause overflow
= 7999 / 255.996
= 1F3Fh / 0100h

Vincent

 

Duh, thanks for setting me straight on that !!

 

Vincent,

I tried your scaling values for V06 this morning and they worked fine. (V06 + vo6) *14 = BV+.

V06 has roughly 98% of the total voltage value with v06 only about 2%. For example, V06 = 15.25V and v06 = 0.25V. v06 seemed to move between 0.0 to 0.30V. Almost like an overflow from V06. You could monitor V06 only and have a close reading of the total value. In case of an issue, you could also monitor the vo6 value.

I am going to check V13 and v13 this afternoon. Should be the same.

Thanks,

Dwight

 

I need a "Prius for Dummies "Book if there is such a thing.. i have a New 2011 Prius lll with Solar roof and Nav.. And just bought a ScanGuage.. BUT have no idea where its to be plugged in.. Been reading the manual's that came with it ..No info there.!!!!!HELP

 

It plugs in to the OBD-II port under the steering wheel column right about where your right knee rests. I just brought my cable up the steering column. If you pull your steering wheel as far forward as possible there is plenty of room to push the cable up the steering column and reach it with your other hand and pull out by the steering wheel.

Once plugged in just follow the ScanGauge instruction manual to configure it to fit your car. The standard gauges will work immediately. Then you can learn how to program the XGauges. If you will go to their Linear Logics website you can find a copy of the Gen III XGauge spreadsheet developed here on PC.

Come back here for any questions.

 

This is right -- I could never get the SGII to be able to send the right frames to use the Main body gateway properly. If we could, we could create a XGAUGE that would turn on the headlights (without turning on any other lights on the car -- kind of a daytime running light for people who don't live in countries that mandate it.

 

If this has not been found I can work on this over Thanksgiving weekend.

 

Yep, that's right. From what I can tell there is a sensor on the engine itself for this PID versus a sensor in the coolant output. Not sure it's really that important to read it, though, as coolant temp is a better average temp.
