Has anyone hooked up an OBDII scanner or linked a laptop via a connector to a Discovery 1997? I have spent quite a bit of time looking at OBDII information and believe it could tell me which one of my wheel speed sensors are failing (ABS comes on after the vehicle has been inactive for a while, mostly at slow speeds.)
The problem is that none of the protocols I see listed for the connector match my pin setup - my Discovery seems to have pins in the ODB2 connector at positions 1,2,4,9,10,12, and 13. This matches none of the protocols that are described below:
PWM The connector must have pins 2, 4, 5, 10, and 16
VPW The connector must have pins 2, 4, 5, and 16, but not 10.
ISO The connector must have pins 4, 5, 7, and 16. Pin 15 may or may not be present.
CAN The connector must have pins 4, 5, 6, 14, and 16.
The ODBII laws say that all vehicles sold in the US after 1996 have to be ODB2 compliant - is the Discovery simply a different protocol, is it not compliant, or am I missing something?
The only other thing I can think of is that I may not have been looking at the correct connector - but the connector I found was under the right hand side of the steering wheel, out in the open, was 16 pin, and looked right...
Any help is greatly appreciated - I'm a new owner, love my Discovery, and just fixed the cruise control tonight based on info I found in this forum
Thanks much,
