New Full Featured OBD II Autoscanner

http://www.actron.com/whats_new_detail.php?id=6

Anyone know anything about these? Are they any better/worse than the Peak scanners?

It was one of the items featured at CES. According to the article you can update it from the web and its only $179. They say you can get it at local auto stores like Pep Boys and AutoZone.

Correct me if I'm wrong, but that style of scanner won't read the BMW-specific codes that the Peake tool reads.

Not sure, but their web site says:

"Use on all 1996 and newer OBD II compliant vehicles: North American, Asian & European."

ODB II codes are universal

All readers will read ODB II codes, the Peake reader translates them to their own codes. The latest Bentleys manual has a chart of ODB II codes. I have used ODB II Explorer software to read codes on my Z.

I don't think a Peake will either

they only list cars to 2003. Z3's appear to be covered though.

Ron, do you have a close-up picture of the OBD-II connector in the car? Good enough to see which pins are occupied?

You could try what I'm using for my in-car PC project, which has thus far connected to everything I've tried it on. I haven't tried their software, since I'm writing my own. But for just reading DTCs, the terminal interface is sufficient. I haven't tried it on an E92 or a Z4M.

Elmscan5 from www.scantool.net

It's based on the ELM327 chip. Speaks ISO15765-4 (CAN), ISO14230-4 (KWP2000), ISO9141-2, J1850 VPW and J1850 PWM.

So by pinout it should be 9141-2 or 14230-4. I think you said it's 14230-4 in a previous thread.

I wonder what's on pins 1, 8 and 9.

What's the voltmeter say for pins 16 (should be ~ 12V) and pin 7 (K line)? Pin 4 is chassis ground, Pin 5 is signal ground (they should be about the same). Pin 7 is the K line, and from memory it should idle high (I'd have to dig through my SAE docs again to be sure).

So pin 1 is additional power? What's on the other end of pin 8 and pin 9? I don't know what's hanging off of X183 and X243 and I don't have any electrical info for the E85 handy.

D_TXD1 and F_TD

TXD1 = Transmitt data 1 ??
TD = Engine speed signal

Looks like X183 is a bus connection. The WDS shows it going to the cluster, the steering angle sensor, DSC and EPS. I've no idea what protocol is on that bus. It looks like X243 goes to cruise control.

My WDS has very little info on E85 with S54. I've no idea how much of it is the same as the E46 M3.
