The light just came on. I'm new to the 90 and have not had a chance to get to know her. But how can I establish what that light means? Is their a coded readout somewhere? |

Not sure on a D90, but on the Disco, there's a plug near the right knee to which an OBD-II reader can be plugged. I'd think that it would be near there, but tucked up behind the dash somewhat on a 90.....
For anything '96 or newer, you will need an OBD-II reader. You can buy a special cable that will let you plug it into the serial port of a laptop and use software, or, you can buy a hand-held reader from Sears instead. Most places like Advance Auto also have one that they can read it for you, or a decent garage should be able to read the code for you too, without you having to go to the dealer.
Good luck,

Yup, it appears the port on the 90 is on the transmission tunnel, in front of the shifter. I guess now I just need to buy the ODB reader. What do those run and which one would you recommend? |

I have an OBD-II cable from http://www.obd-2.com/ for $122 that I like, but you need a computer to attach it to... if you have a laptop, it is what I would recommend. You could get a longer cable and attach it to a desktop, if you can set your desktop up close enough to get the cable into it.... I wouldn't recommend that, though. One nice thing is, this fellow has developed Rover-specific codes.
Sears and places have them that are entirely self-contained, with built screens, etc., that go for a bit more than that, but, it saves you from using a laptop.
Also, see this page. http://www.spanishtrailrovers.com/Tech/Info/OBDII_Scan_Codes/obdii_scan_codes.html
Hope that helps!

Thanks Leslie. This is excellent info. How much ecu or Rover specific info are you able to discern from this OBD-2 setup? |

From the OBD-2 site, it states that the requirements that are monitored are:
Catalyst
Heated Catalyst
Misfire and Misfire for Diesels
Evaporative System
Secondary Air System
Air Conditioning System Refigerant
Fuel System
Oxygen System
Exhaust Gas Recirculation (EGR) System
Positive Crankcase Ventialtion (PCV) System
Thermostat
Comprehensive Component
The big thing that I used it for was clearing the light when it had had a misfire. I never really explored it fully before I traded that Disco off. The one we bought today is an OBD-I Disco, so I'll be using the cable on my Subie now......
Good luck,

Leslie, thanks again.
BTW, what year Subaru do you have? I have a 2001 Outback, and it would be pretty damn cool, and increasingly justifiable if I could use it on that as well.
Thanks! |

I've got an '02 2.5RS.
Any vehicle made for the US market since the 1996 model year is required to be OBD-II compliant.
There are 3 plug-types, though. There's a "GM" plug (VPW), a "Ford" plug (PWM), and a "Euro/Jap/Chrysler" plug (ISO). Note, there are exceptions, such as some Toyotas use the VPW plug, some Fords use the ISO plug, etc. etc. etc. You can get combination plugs that work with all types, if need be, but I just have an ISO plug.
On the Subaru boards, some people prefer some other fancier types, because they're trying to remap chips for racing purposes (well, on the Imprezea board, at least), but have had good success using the OBD-2 cable too, when you're not trying to reprogram the chip.
FYI, http://www.i-club.com/ is the Impreza board, which also has other Roos on there, too, the way here has this Defender board on DiscoWeb....
