4 Speed Auto Temp PID for pre-2011 facelift models

[ptommo59]

I started trying to help another member workout how to get the A340F 4 Speed Auto Trans Fluid Temp reading for his 2008 Hilux 1KD-FTV onto his Scangauge II and got stumped as I don't have access to a vehicle to directly capture the required data from the vehicle to assist with reverse engineering the required code. We tried several published CANSF/KWP/ISO scangauge codes but got a fixed 177 or no response from his scangauge and ended up giving up.

From my research the N70 2011 facelift models on were OBDII compliant and used CANSF as the communication protocol so the published ATF10 (Pan Temp) code on the Scangauge Aust website works (even though they say it only works with the A750F 5 Speed).

For the earlier N70 models the communication protocol varies between years and engine type (I only looked up those that were fitted with the 16 Pin OBDII style diagnostic connector):

* 1KD Diesel pre 2007/1GR V6 Petrol pre 2006 with the 16 PIN OBDII style connector used a custom Toyota protocol based on KWP2000 5 Baud Init but at 9600 Baud and M-OBD. (Scangauges don't support this hence why they won't work on most pre 06/07 models, but those with Torque Pro or other Apps can enter a custom init string to get it to work).

* 1KD Diesel 2007-11/1GR V6 Petrol 2006-11 was OBDII compliant but used KWP2000 Fast protocol (Scangauges work with these in ISO mode but we weren't able to get it to respond to any published X-gauge KWP/ISO codes).

Anyone else had a crack at this and able to provide more info on what KWP2000 headers the Hilux is using on the various years or what addresses it is using for the Engine (10/12/13?) / Trans (19?) ECUs and Test Equipment (F0 or F1) ?

Update:
As covered in the original post I have been trying to workout the Auto Trans Pan Temp code for the pre-facelift 4 speed Hilux that uses the ISO mode on a Scangauge 2/3 (07-11?).

The Scangauge Aust team have recently given me a code that has worked on other Toyota ISO models, can someone with a scangauge and Hilux using ISO mode setting give this a try and let me know if it works.

Hey ptommo59

How did you go with this?
The two you mentioned above show blank for me - 2009 Hilux 4 Spd Auto.

I have been trying for a while but getting nowhere

[ptommo59]

Located a thread on here that confirmed the 2007 - 10 Hiluxes are using KWP2000 Protocol so the two above x-gauges definitely wont work as predate that change.

Sent you a PM to try a few commands to see what comes back on the SG2 for the standard OBD parameters supported by your Hilux.

Will then potentially be able to work out a strategy to come up with a few extra x-gauge codes.

[ptommo59]

Can someone with a 07-10 Hilux and Scangauge try these codes and see if you get anything displayed (should be Engine RPM info from the Engine and then Trans Computers). Keen to know if we can access these so I can try to get the correct code for the Trans Pan Temp Sensor and whether its available from one or both computers.

An update for anyone following this topic...

A Neighbour just purchased a 2008 Hilux SR so I was able to connect a Techstream computer and SG2 to it to see what parameters it supported and checked a few SG codes to confirm they work.

His Hilux even though 2008 on the registration was reporting as a 2006 on the ECM data so info seems to be relevant from 2006 KWPF/ISO versions through to the MY11 facelift update to CANSF.

I was able to communicate with both the Engine ECM and transmission TCM via the SG2 using the Headers 8210F1 and 8219F1 as per first part of the TXD in previous post (so promising).

The ECM & TCM Live Data lists on Techstream had all the standard parameters on the facelift 4 Speed models, which again was promising that they can be accessed with an SG:

I confirmed both codes in the previous post worked and that the TCM appears to be using the same 21D9 code for the Trans Pan Temp and 21DA for the Current Gear and TC Lock status as both were supported.
I got a valid response from 21DA and could see the gear changes and TC lock status changes using this code:

TXD: 8219F121DA
RXF: 0319046105DA
RXD: 2808
MTH: 000100010000
Name: GEL

P/N/R/1st report a 1 then 2, 3, 4 on upshift with TC unlocked.
As I didn't separate the TCL, when it locked in 4th the gear nunber went to 20 (lock bit setting added 16 to gear number).

21D9 was not responding on the SG2, so my current assumption is that because it is longer than 7 bytes (in the facelift CANSF version) the SG firmware is not able to process or does it a different way, but I need to do a bit more experimenting when I can get to the Hilux again.

hope this is useful

Next Update:

I have confirmed with the Scangauge Engineers that the SG2 in ISO and KWPF Modes cannot process messages longer than 7 data bytes which is the SAE and CAN standard frame length.

The A340F 4 Speed Trans Pan Temp from the TCM is in 21D9 which has a 10 Byte Response so its a no go for the SG2 using current firmware unless Toyota replicate trans temp info on a different ECM message that is less than 8 bytes long (but not found as yet).

Good news is they are looking at potentially updating the SG3 firmware in a later release to solve this for the SG3. So keep an eye out for info on support for the 06-10 Hilux Trans Temp and others if you want to go down that path.

What should work now on both the SG2 and SG3 are the 06-10 Hilux A340F 4 Speed Current Gear and TC Lock Status using these X-gauges:

Current Gear

TXD: 8219F121DA
RXF: 0319046105DA
RXD: 2D03 (or 2C04 as same response)
MTH: 000100010000
Name: GER (P/N/R/1st is shown as 1)

Torque Converter Lock Status

TXD: 8219F121DA
RXF: 0319246105DA
RXD: 2B01
MTH: 000100010000
Name: TCL (OFF/ON)

For those with Torque Pro I am not certain if the same restrictions apply so probably worth a try of the Trans pan temp as well (These are for the N70 Hilux using ISO or KWPF Comms Mode. Should also work if you change OBD Headers to 07E1 for MY11+ Facelift CANSF comms models):

Mode/PID: 21DA
Long Name: Trans Current Gear
Short Name: GER
Minimum Value: 1
Maximum Value: 4
Scale factor: x1
Unit Type: Gear
Equation: BIT(A:0)*1 + BIT(A:1)*2 + BIT(A:2)*4
OBD Header: 8219F1

Torque Converter Lock Status

Mode/PID: 21DA
Long Name: Torque Converter Lock Status
Short Name: TCL
Minimum Value: 0
Maximum Value: 1
Scale factor: x1
Unit Type: Status
Equation: LOOKUP(BIT(A:4): :0='OFF':1='ON')
OBD Header: 8219F1

Mode/PID: 21D9
Long Name: Trans Pan Temp
Short Name: ATF
Minimum Value: -40
Maximum Value: 215
Scale factor: x1
Unit Type: °C
Equation: E-40
OBD Header: 8219F1

Hope this is useful

Please let me know here if any of the above don't work properly so I can try to correct/fix error.

Edit: If anyone tries above and gets no response when in ISO Mode try forcing the SG to KWPF comms mode.
Seems the Hilux in that era was able to use both ISO and KWPF comms but may only respond to the above x-gauges in KWPF mode,
