OK, it seems like you have interpreted the offset incorrectly. Let's relook at your real data:

	Bit offset	0	8	10	18	20	28	30	38	40	48
1	Byte no.	1	2	3	4	5	6	7	8	9	10
2	First	07	EA	[/COLOR]10	11	61	92	3B	64	08	3C
3	Consecutive	07	EA	21	08	0D	0E	00	00	00	00

block minimum voltage 7EA 10 11 61 92 (3b) (64) 08 3C
$3B64 = 15204
15204 * 7999 / 65535 = 1855 => divide by 100 = 18.55 V

block number with minimum voltage 7EA 10 11 61 92 3B 64 (08) 3C
$08 = 8 => is any no. from 1 to 14

block maximum voltage HB 7EA 10 11 61 92 3B 64 08 (3C)
$3C = 60
60 * 7999 / 256 = 1874 => divide by 100 = 18.74 V

block maximum voltage LB 7EA 21 (08) 0D 0E 00 00 00 00
$08 = 8
8 * 7999 / 65535 = 0.98 => divide by 100 = 0.0098 V

block maximum voltage = block maximum voltage HB + block maximum voltage LB = 18.74 + 0.0098 = 18.75 V

Number with maximum voltage 7EA 21 08 (0D) 0E 00 00 00 00
$0D = 13 => is any no. from 1 to 14

Number of battery blocks 7EA 21 08 0D (0E) 00 00 00 00
$0E = 14 => is the total no. of battery blocks

Ok, ok, offset error, but then

block maximum voltage LB 07E22192 010702EA0321 2008 1F3FFFFF0000 Vhi divide by 100 to get volts
block number with maximum voltage 07E22192 010702EA0321 2808 100010000 bhi Any of block number 1 to 14

must be 18 and 20...

Thanks.

 

Vincent and Adrian,

After a couple of weeks of monitoring two of the above PID's at a time I just want to post my observations here:

MG1 Inverter Shutdown
MG1 Inverter Fail
MG2 Inverter Shutdown
MG2 Inverter Fail
Converter Shutdown
Converter Fail

All of these reported OFF. These will be useful when troubleshooting an actual problem.

DC/DC Converter Duty Pulse - Changes between power ups but is mostly fixed while driving.

Water Pump Run Control Duty - Only saw around 3.9% and very little change if any. This is with fairly wide temp swings between cold mornings and moderately warm afternoons.

Battery Block Minimum and Maximum Voltage - Updates continuously and difficult to determine difference, especially with HB and LB for max. Would need to trend to be able to get an average difference reading.

Block number with max voltage - always 14
Block number with min voltage - varies between 1 to 13

According to Service Manual the DC + cable to the Converter/Inverter is connected to Block 14 and the DC - cable connects to the Block 1. This may explain why Block 14 is always max voltage.

Number of Battery Blocks - O (Should be 14)

Delta SOC - ranged from 55 to 65%
SOC Max - ranged from 50 to 60%
SOC Min - always 0

Delta SOC is always greater than SOC Max. These values change mainly only on power up. Must be values from last power on sequence. Even though the Delta and Max values are reasonable they do not appear to be labeled correctly. With the min being 0 I would expect the Delta to be equal to or less than Max.

If there is anything else you would like to test or try with these PID's, let me know.

Thanks for the continued assistance and guidance,

Dwight

 

Thanks Dwight!

As pointed out by motoleon, I've the offset wrong for these 2. It is easier to spot the error if I've the real data, sorry!

I agree those values aren't correct, most likely cause by the wrong offsets as well. It seems there is 1 byte offset as above.

Ok, thanks to you for your work.

Salu2.

 

Vincent,

I tried the above offsets and it looks like 3 out of the 4 are now working correctly.

SOC Max
SOC Min
SOC after IGN-ON

The SOC IGN-ON gives what it says the value of SOC when you power up. SOC Max and Min will follow the max and min SOC value and increase or decrease each time you exceed the previous max or min. I did an extended EV run and then after the SOC recovered to 60% I did several hard regen stops. The min fell to about 50% and the max rose to about 70%. The max and min followed these values each step of the way.

Delta SOC = 0.0 This value never changed. It looks like we have some more work on this. Any ideas?

I will start testing the new offsets for the battery voltages next.

Thanks,

Dwight

 

Thanks Dwight.

The screen capture from The Critic also shows 0.0. I think it should be correct.



My Gen 1 is showing 20% all the time. My guess is Toyota may have changed the default display value for later Generations, that value may only change when there is big SOC difference between the battery blocks.

Vincent

 

Vincent,

I looked up the Delta SOC parameter in the 2010 Service Manual and found this description:

Tester Display - Delta SOC

Measurement Item/Range - Difference between maximum and minimum values of SOC /
Min.: 0%, Max.: 127.5%
Suspected Vehicle Status When Malfunctions Occurrs - SOC variance ​

That makes it sound like it should be the difference between SOC max and min does it not? Maybe it has to exceed a certain value before it is considered a malfunction and displays something other than 0.0 as you said?​

Thanks,​

Dwight​

 

Vincent,

I retried these above with the new offsets. They all are working fine now.

Battery block with maximum voltage LB
Battery block number with maximum voltage
Number of battery blocks = 14

The battery block with maximum and minimum voltage seemed a lot more stable to compare now, especially at a steady state such as highway driving with cruise control. Much easier to read and compare max and min. Battery block with max voltage now varies between 0 to 13 much like the one with min voltage.

Have you come up with any more PID's to try?

Thanks again for your support and assistance,

Dwight

 

Thanks Dwight

Vincent,

I will work on the new PID's this week and let you know how they work.

Take a look at my post #469 below about Delta SOC and let me know what you think.

Thanks,

Dwight

 

It does sound like but I don't think it is clear. It does not tell you whether it is the SOC difference of the whole Bty Pack, the individual Bty Blocks or something else. You have observed the SOC Max. & SOC Min., does the difference equal to zero? No, right?

The Service Manual also states:
READY indicator on, engine stopped and no electrical load: 0 to 60%

0% is a valid response. If the range were to be 20% to 60%, then you should suspect something is wrong.

Vincent

 

Vincent,

The SOC Max and Min are only equal to zero when you first power up. After that they separate as the SOC varies. In normal driving there is at least 10% difference.

I have been in Ready mode with engine stopped many times at stop lights, etc. Not sure about no electrical load. Only electrical load would be radio, heater controls and interior electronics. I have never seen anything other than 0.0. I will have to try it with everything off and see if anything else is displayed.

I would expect it to read the difference between SOC Max and Min but evidently not. If it were to go above say 20% then trigger a DTC.

Maybe someone will help us figure this out.

Thanks,

Dwight

 

Vincent,

I tried the MG1 PID's and they all worked fine. The MG1 temp one, M1c, matches the one in Adrian Black's spreadsheet. This apparrently the same value with different parameters.

I then tried the Water Pump Running, this gives me OFF and have not seen it go to ON with engine running and pressing accelerator in Park. I need to try this some more while driving.

The Inverter Water Pump RPM showed between 750-850 RPM so seems to be working fine.

The Auxilary Battery Voltage gave me 44.4V. I checked the parameters and they are correct as given. You may want to check the scaling on this one.

I will try some of the rest tomorrow.

Thanks,

Dwight

 

Adrian Black only uses MG1 temp. max.

I'll check that again.

It seems low, RM states 1375 to 5500 RPM in READY. Might need to adjust the scaling.

Vincent

 

Vincent,

I tried the new scaling for the Aux Battery and it returned 14.4V and was about 0.2V below the SGII VLT. When I tested the voltage at the jump point the VLT displayed 12.8V and the vlt still displayed 14.4V with the DVM displaying 12.8V. I am not sure what this is actually reading. The VLT moved up and down a little while driving while the vlt remained constant.

I tried the VB signal and it compares to Adrian's VB+ signal. So this one looks good.

I also tried the VMF signal and it returned 0.0 and remained there. Of course it is in the 40's today so probably does not need the fan to run.

Thanks,

Dwight

 

Vincent,

I tried the two Cooling Fan PID's the other day. The Relay Status was always on and the % was usually 0.0. After driving in town yesterday with a lot of stop/starts the Cooling Fan came up to the 40-50% range. I need to go back and monitor the VMF signal again after driving around town again and compare the voltage signal against the % speed signal.

I also tried the Inverter signals this morning. The OAT was 63F this morning and the IGN-ON value was reported at 116F and when I started driving it went up to the 130-140F range. I compared this against Adrian's signal which reported 73F on startup. Adrian's signal appears to be more reasonable. Adrian's signal ranged from 73-103F while driving and the three signals above ranged from 116-146F. I think you need to check your scaling on these values.

Check below for my post on the Aux Battery signal. This appears to either be a scaling issue or this is reporting the DC/DC Converter charging voltage and not battery voltage. When I turned off the car this voltage remained in the 14.4V range.

Thanks,

Dwight

 

When you power off the car, SGII will wait for about 12 secs. when it detects no more CAN signals. Once it is timeout, SGII will save what were displayed to Flash memory before it goes into sleep mode. On your next power up, SGII will restore what were displayed the last time before it went to sleep. Once there are responses received by SGII, the restored values will be quickly updated by the new values.

However, if you don't power up the car but press HOME to wake up SGII, the display will only show the restored values but there will be no updates because the ECUs are off. That is why you saw 14.4V. You need to re-select the gauges so that it will refresh the value. After refresh, most probably you will get blank display since the ECUs are off.

The VLT is not read from ECU but from SGII's internal ADC circuit. vlt is reported by ECU and the update intervals may not be as frequently as VLT.

Vincent

 

Vincent,

That makes sense about the ECU being off and not reporting vlt. I will try this again and use ACC mode which should keep the ECU energized. The vlt signal did show about 0.2V higher than the VLT signal while driving. The VLT signal appears to be correct per the DVM.

Thanks,

Dwight
