4 Speed Auto Temp PID for pre-2011 facelift models
Posted: Mon, 27 Nov 2023 8:44 +0000I 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) ?
