OBD-II

[Mike Fahrion]

The OBDII Bible is SAE's HS-3000 (1997), $79US.  Available through 
SAE's home page at www.sae.org.

I'd guess that the BMW uses ISO9141 type communications (one of 
the three "standards" allowed under OBDII) - contact CarComp 
(www.carcomp.com).  They offer a ISO9141 to RS-232 product.  If it 
uses J1850 VPW communications (I doubt it), contact me....  CarComp 
will be able to tell you if their tool will work on your car.  The 
protocol and commands are (nearly) identical across the three types 
of communications, but the hardware varies drastically.

I've got a bit of time invested in this OBDII thing, feel free to 
email me specific questions and I'll do what I can.

Good Luck
