E90 320i Help With OBD II Port
Hello again Dave 👋, well, as of this time I'm still having issues establishing a connection with INPA. I'm certain I have everything on the laptop setup properly. Adapter is set to COM1 and latency is set to 1. I'm wondering if maybe the driver is the issue? I was told that the resistor is a "terminating resistor". It seems each device (and the OBD port qualifies as a device) has to have a certain resistance across those CAN lines. So I don't think the wiring is causing a communication issue at this point. Wiring is factory and should allow for communication with INPA at the very least. The adapter I have does have a 3 position switch, and to be fair I only tried two of the three positions. I'm heading back out to the car now and I'll attempt establishing a connection through INPA one more time while moving the switch between the 3 positions to see if any one position makes a successful connection. I'll come back with results on tha. I'm still wondering if the issue is the JBE module or some other module that is causing the communication issue, but how exactly do I test for that? If your ex neighbour could assist that would be amazing! I really appreciate it Dave 🙏 I'll attach the adapter settings in case you want to look over them, as well as the adapter switch and wiring. -

E90 320i Help With OBD II Port
Morning Tino INPA/ISTA should recognise Chassis and ECU data and harvest it automatically, well mine does. I get Chassis information, Engine and any history recorded Just sitting with a Coffee studying the wiring diagrams up to 2007 and 2007 shows a resistor symbol in connector X13376 at Pin 1 Green/brown trace 2007-2009 shows no resistor symbol anywhere X13376 connector appears to be part of the vehicle access system it links to the DME Pin 2 Black/green trace that is part of the Start system Later today I will try and talk to an ex neighbour who is now a senior guy in BMW see if he can find any more help Dave -

E90 320i Help With OBD II Port
Hey Dave 👋 I'm back! I'm wondering if the resistor is causing software not to be able to communicate with the ECU because the initial connection is normally established. The issue is when further communication starts then it just falls off and goes dead. Even with INPA, I borrowed a laptop with INPA from a friend that works on BMW's and it's acting strange. INPA sees ignition on all the time once OBD adapter is connected with a light on at all times on the adapter. The light on adapter stays on until getting into any sub menu. For example, E90>Engine>N45/N46. The light goes out and when entering the engine option menu I get an error "Group file : D_MOTOR. IFH-0009: NO RESPONSE FROM CONTROLUNIT. Program will be stopped!" After pressing okay it takes me back go the main menu. Also, when entering the "Functional Jobs" menu, and trying to enter the E90 menu I get the error "Language variants do not match. Malfunction possible!" After pressing okay it takes me to the E90 Menu under functional jobs. When I try to press on identification or vehicle data I get the message "no response from the control unit." I want to note that whenever I enter a new menu the adapter light blinks rapidly for a few seconds like it's showing me some type of data communication is happening then it just stops. I'm wondering if the settings of INPA need to be configured a particular way in order for it to communicate with this BMW or if a module has gone bad. Hmm, maybe I need to test the resistor to make sure it's fine. Maybe just get rid of the resistor all together? I'm not sure what it's purpose is but if all other E90's can operate without it then I'd imagine it'll work without em as well but not gonna jump to any conclusions yet. -

Help with 2014 X3 RDC and TPMS
Morning JC Borrowed my neighbours i-Carsoft last evening and it does a lot more than I thought but sadly not with the RDC. So that's not the one Normally you need to erase the old chassis number or last 7 digits then ignition off wait a few minutes ignition on and check it's cleared then enter your information From what I have read online guys using Foxwell have had some success but for me I would look for a Copy of ISTA with it's leads (mine came from ESYS years ago) one of our sons friends brought a copy 2 years ago from the Bay £110 I helped him get it up and running on his Win 10 Laptop, downloaded a Virtual Machine Win7 then loaded the program to that, the only faff was loading the drivers took 3 try's. It works really well and like mine allows full Dealer level access for Diagnostics and Programming Good Luck Dave
