Hi Bimmers,

I am desperately trying to gt some information as to why I can't get INPA to communicate with a 2008 E90 (2008).

I am using a K+DCAN USB cable and INPA v5.06.

INPA will recognise that the car is connected , search for errors, but return with the following message;

IFH-0009; No response from control unit.

IFH-0009; No response from control unit. Cranks But Car Won’t Start
I use INPA regularly on my 3/2007 328xi, using BimmerGeeks K+DCAN Cable, so am familiar with how it SHOULD work, and a few of the setup gremlins. So if you will answer the following, we can help:

QUESTIONS:
1) What Brand K+DCAN Cable did you get?
2) Have you set COM PORT Settings to COM1 & Latency 1?
3) If you just plug your cable USB plug into your computer USB Port/Socket, does the Light on the large Cable Head (OBD II Connector) light for a second or so?
4) Does your Computer Control Panel > Device Manager > Ports setting appear when you plug Cable into Computer?
5) If so, select USB Serial Port > Port Settings Tab > Advanced Box > Port# = COM1 > Latency = 1
6) After Setting up your COM 1 Port, disconnect Cable from computer USB Port, and take it to vehicle;
7) Plug Cable into OBD II Socket, WITHOUT it being plugged into computer. Does Light on large connector light for ~ 1 second. If NOT, test for 12V+ with Ignition ON at pins 1 & 16 of USB Socket. Pin #1 is Lowest OUTboard (next to Door) socket, and Pin #16 is Upper INboard (toward pedals) Socket;
8) When you say "INPA will recognize car is connected", explain PRECISELY what you have selected AFTER Connecting Cable, turning on Ignition, opening INPA, and clicking on "E90".
9) At the Script Selection box, which SHOULD appear when you click "E90" at opening screen, Click "Functional Jobs" in the Right-Hand Listbox (or press Tab to navigate to Right Listbox, and select FJ).
10) If you get Functional Jobs Menu, Open and Save Two Screens: (A) Functional Jobs > F2 Identification, which contains a list of all ~ 20 Modules in your vehicle, and (B) Functional Jobs > F4 Error Memory, ALL Modules.

If you get that far, post those two screens for "Next Steps". If the wheels come off at any point, tell us PRECISELY WHERE in the steps above. The reported instances your Error Message, when you Google IFH-0009 include Cable issues, with improper cable, mis-wired cable, etc. If you have ANY Generic P-code Scan Tool you can borrow from a friend, etc., that would be the quickest way to determine if the OBD II Socket is functional. Here is one of many discussions of IFH-0009 Error Message:
I attach a pdf that shows what basic Functional Jobs INPA Screens mentioned above look like, HOW to set COM1 Settings, and HOW to Save ScreenPrints as jpg format files you can reference later, and/or attach here. Please let us know what you find.

Hello gbalthrop,

Thanks a lot for for your help , please find bellow my commets


I use INPA regularly on my 3/2007 328xi, using BimmerGeeks K+DCAN Cable, so am familiar with how it SHOULD work, and a few of the setup gremlins. So if you will answer the following, we can help:

QUESTIONS:
1) What Brand K+DCAN Cable did you get?
R: I dont´t know the brand it was parchased on ebay but im sure that it works and also is propertly set up because I used the same cable to scan this vehicle in the past also today I tested on another E92 same year and the INPA & INSTA+ works fine so i beleve that the issue is not the cable but the response from the car.
2) Have you set COM PORT Settings to COM1 & Latency 1?YES
3) If you just plug your cable USB plug into your computer USB Port/Socket, does the Light on the large Cable Head (OBD II Connector) light for a second or so?YES it turns a red light
4) Does your Computer Control Panel > Device Manager > Ports setting appear when you plug Cable into Computer?
5) If so, select USB Serial Port > Port Settings Tab > Advanced Box > Port# = COM1 > Latency = 1 YES
6) After Setting up your COM 1 Port, disconnect Cable from computer USB Port, and take it to vehicle;
7) Plug Cable into OBD II Socket, WITHOUT it being plugged into computer. Does Light on large connector light for ~ 1 second YES the red light turns on for some seconds. If NOT, test for 12V+ with Ignition ON at pins 1 & 16 of USB Socket. Pin #1 is Lowest OUTboard (next to Door) socket, and Pin #16 is Upper INboard (toward pedals) Socket;
8) When you say "INPA will recognize car is connected", explain PRECISELY what you have selected AFTER Connecting Cable, turning on Ignition, opening INPA, and clicking on "E90".
R: I have selected Funtional Jobs-- Read memory error but it shows the folowing error "NO RESPONSE FROM CONTROL UNIT" , also with INSTA+ when i select read out vehicle data the software try to read the modules and then shows an error "It has not been possible to identify the vehicle. Check access to the vehicle and whether the diagnostic-analysis-check is active"
9) At the Script Selection box, which SHOULD appear when you click "E90" at opening screen, Click "Functional Jobs" in the Right-Hand Listbox (or press Tab to navigate to Right Listbox, and select FJ).
10) If you get Functional Jobs Menu, Open and Save Two Screens: (A) Functional Jobs > F2 Identification, which contains a list of all ~ 20 Modules in your vehicle, and (B) Functional Jobs > F4 Error Memory, ALL Modules. I can acces to the options but can´t connect with the vehicle please see the screens

If ISTA Can't identify vehicle, and INPA says "No Response from Control Unit" when you try to read Fault Codes in ALL Modules (Functional Jobs > F4), then my SWAG is that there is a loose/shorted D_CAN wire between the the OBD II Socket & the JBE, OR a loose/shorted wire in the K+CAN bus. Since the JBE is the BUS HUB, and INPA says No Response from Control Unit, I would interpret that as OBD II Socket NOT connected properly to JBE Module (HUB), OR other BUS Fault that shuts down entire BUS Communications System.

I don't know what 2008 Model you have, so the attached OBD II Socket SSP from ISTA may NOT be correct for your vehicle. The attachment is for 2008 E90 335i with N54. You can use ISTA to do a search for "Documents" such as SSP wiring diagrams for YOUR vehicle. You do NOT have to be connected to the vehicle.

Just enter your Last-7 Characters of VIN at "Operations" Tab VIN entry box, and your vehicle Identification should appear after ~ 5 seconds. Then Select "Vehicle Management" Menu, "Troubleshooting" Submenu, and than "Text Search" Tab. In "Search String" box, enter "OBD II Socket" and you will get an SSP circuit similar to the attachment. You can also enter "System Bus" to view wiring for K-CAN Bus, or "Powertrain CAN" for PT-CAN bus system wiring.

I would begin by checking for loose wires or metal pin sockets pushed out of the OBD II Socket plastic Housing, particularly Pin #6 (White/Yellow wire) and Pin #14 (White/Blue wire). Then DISconnect the Connector X14271 at the JBE Module (Installation Location attached), and check for corrosion or damage to pins & sockets, particularly #17 & #33.

Hello George,

I have inspected the OBD II Socket & Connector X14271 and all the cables and pins look good also i used dielectric cleaner and nothing-----

I was thinking to check the continuty between the OBD II socket and the Connector X14271 but i couldn´t find the the (White/Yellow wire) and (White/Blue wire) on the Connector X14271, What do you suggest me to do?
VIN#A056137
