Urgent: Can't read OBD II port

The car is 2000 528 Wagon.

I did annual MA state inspection in June. They failed me, telling me they can't read the ODB.

Then our first baby came, you know how was life then. I finally have some time to check the problem today, before the 2 month deadline next week.

1. I bought a ELM327 USB OBDII cable, connect to my computer, run ScanTool.net 1.13, select according COM port. The software tells me Connection to interface was lost. Also ELM327 has 5 LED light, only the red light is on, just as it connect to nothing.

2. According to the car's fuse diagram, 3 fuses for On-board monitor, 43, 56 and 58. I checked all of them, no problem. (these 3 fuses also governs radio, which working good)

3. Google tells me line 16 of OBDII port is battery power, line 4/5 are ground. I metered them, zero voltage.

In summary, both OBD reader from inspection station and mine can't read the OBD II port. All fuses are good. No voltage on OBD line 16.


I am stuck. What to do next? replace the OBD port? take it to dealer? Please help.

Sorry, but it certainly sounds like there is a problem with the port itself on the car. You probably are going to have to take it to the dealer to be corrected. Keep us posted on what they find.

Sounds like you did a thorough job of checking every thing you can. BTW, I have the ELM 327 scanner and using Scan Tools software, and it works great on my BMW and Ferrari, no problem.

Being an emission related device, this may be covered under the 8 year, 80,000 mile federal emission warranty...worth asking your BMW dealer.

See this:

There are three specified major emission control components,
covered for the first 8 years or 80,000 miles of vehicle use on 1995
and newer vehicles:

* Catalytic converters.

* The electronic emissions control unit or computer (ECU).

* The onboard emissions diagnostic device or computer (OBD).

Hi, 540 M-Sport, thank you for your kind reply. When ELM 327 connect to ODB correctly, how many LED lights are on? I am sure it's more than just the single red light, just want to have a idea what to look for.

Can't remember, but no red, that is for sure! Take it to the dealer, if you are under 80k miles, look like you get a free repair!

I went to go check, and I'll be darned, I can't find the cord! crap

I do recall it took me several tries and using various "com" port settings to come up with the right combo to get it to work, so try them all.

BTW, the ELM scanner will only show the red light, until the Scan Tool program recognizes the ELM scanner and starts communicating, then the red light (I believe) extinguishes and the other lights begin blinking (green and yellow)

I did some measurement, all reference to a reliable ground point. (the big metal bolt close to DLC)

Round DLC 14: 12v when ignition switch ON.

Fuse 25: upside 12v, downside 10v when ignition switch ON or OFF.
upside 14v, downside 12v when engine is running.
(does that sound normal?)

OBD pin 16: no voltage when ignition ON, OFF or engine running.
OBD pin 4/5: no voltage when ignition ON, OFF or engine running.

This is OT but I'm curious ... (for the benefit of this freeware thread) ... is this the three things recommended to get the freeware to work on the OBDII port.

CABLES:
- ELM327 USB OBDII cable

FREEWARE:
- Scan Tools v1.13 for WinXP

COMPUTER:
- Windows XP SP3

Yes, that is one of the combinations I am using.

Hi, just want to report back. My OBD problem is fixed.
Notes:
If you can't read your OBD port:
1. Make sure the cap for the round 20-pin DLC (datalink connector) under the hood is properly closed. (if your E39 has DLC, that's the common culprit)
2. Check fuze 25 inside the glovebox
3. buy a ELM327 OBD-USB cable, download free software scantool or easyobdii, try to read it by yourself (if the software can't recognize the hardware, make sure you set the correct COM port and Baud Rate, or just try all the possible combination)
4. Measure Pin 16 on OBD port, it should has voltage when ignition key in position 2. (it's hard, I didn't get any voltage even after my OBD went back to normal state)
5. replace DLC cap
6. buy a 20 pin DLC to OBD cable, try read from there.
7. I don't have any further solution :-)

I want to thank Derek, Jim, Dan, 540 M-Sport, Qsilver7 for all the helps.

Great! I added your recommendations to the OBDII freeware thread.
The main problem, for newbies like me, is where best to get the OBDII ELM cable since Ebay scares me.

I have a 1998 540i. I couldn't connect to the car even though I've done so several times before. Mine was because the cap under the hood was left off last time I changed the oil and reset the service light.

Um...you may be the idiot. You are in the E39 forum and ALL North American E39s have an OBDII port. You may want to stick to the E34 section to avoid any further frustration on your part.
