Scangauge xcodes9/15/2023 Off topic, but there are deeper privilege levels that require a cryptographic challenge/response exchange to unlock… among other functions, the injected fuel quantity, smooth running test, and high idle speed all lie behind this challenge/response wall. Use of the absolute address (12) may be required to open up Service 21? The EMU’s firmware does have a few hurdles placed between these interfaces and the data we seek, and I can’t remember if it makes Service 21 (the “get data block #” request) available when the functional address is being used in the query message? Certainly the DTC values sent using OBDII ServiceID 03 are different than the “native” codes sent from ServiceID 18. The OM647 is listening on both 12 and 33, and uses 12 in all its response messages, so the SC *can* tell it has a session open at that address… indeed some scan tools will broadcast on functional address 33 to get the engine ECU’s attention, then use the absolute address from the initial response as the target address for the duration of the session. This is the code for an Arduino-powered tachometer/scan gauge. There’s a bit of bus work required to establish a connection with the ECM, so the SG may filter out other node addresses thinking it doesn’t have an open session and not wanting to establish a new one. Alex Neimans Real time diagnostics OBD Scan gauge tool. (If you know of more, please feel free to add to the list) FICM Vehicle Power (Volts) (Should be 12 Volts) (should not drop below 10.25 for more than 60 seconds, or 9.0 for 4 seconds. 273.1" not "-2731" )Ĭlick to expand.This *shouldn’t* matter?Ĭonjecture: the SG may be balking at the use of the absolute address (12), since most OBDII devices use the functional address (33). ScII Codes for Xgauge Now Injectors Collected from different threads and members. The data locations are in post 211, though the formulas are off (temps should be ". Ps: the available engine data is extensive, and explored in the thread "Cracking the K-Line", starting around post #207. So XGauge entry for engine oil temp in degrees Celsius should be: I have a 2008 Toyota Tundra 4.7L (no tow package). XGuage uses a bit offset, so skip 21x8=168 bits (A8), then read 16 bits.įormula for Celsius is divide by 10, then subtract 273 (add -273, or $FEEF) 00070064FE70 Name: TFT Notes: Degrees F (I am guessing this is set in the 'set-up' menu for the ScanGauge because I don't have an option to change it after inputting all other codes) However, when I bring up TFT it yields no reading. Reply message has bytes 22 & 23 encode 10x the oil temp in Kelvins. I notice it typically runs 30-40’F above coolant temperature, but when climbing long grades the oil gets hotter faster than the radiator. A lagging value to be sure, but the oil sump temp gives some information on the heat being soaked up by the oil cooling the pistons. I’ve got my arduino device set up to display engine oil temperature. The Digital Gauges and Trip Computer information can be shown in either English or Metric units of measure, including Kilometres, Litres, Celsius, and kPA.Click to expand.I’ve recall a thread where an EGT sensor was tapped into a hole drilled through a meaty part of the exhaust manifold. Match your instrument panel for an integrated look. Simple 5-button operation allows you to quickly and easily access the powerful features of the ScanGauge 2. The included Velcro® attachment system allows the ScanGauge 2 to be quickly detached and then used to troubleshoot other vehicles. STANDARD OBDII Find a listing of generic and common OBDII XGauges such as O2 Sensor Voltages, Long and Short Fuel Trims, Air-to-Fuel Ratios, Fuel Level, and more for all the major protocols. The ScanGauge 2 can be mounted up to 6 feet from the under-dash diagnostic connector. ScanGauge 2 automatically determines the protocol your vehicle uses and connects. The single connection to the diagnostic connector under the dashboard is all that is needed. Simply plug the ScanGauge 2 into the diagnostic connection under the dash.
