Yep.TimMullen said:I would expect that the Elise will work with the any standard ODB-II scanner that supports the proper protocol
I think we already had one confirmation that a standard (ISO-9141) OBD-II scantool works fine.
The other formats use different pinouts, so it's not hard to be certain.
In fact, the Elise may not send basic OBD diagnostics over CANBus at all. They have no specific requirement on the CANBus and can use it for whatever data they like, so long as the OBD requirements are met on the K-Line (ISO OBD-II).
The fact that the CAN-Bus is also available from the same plug just adds additional capabilities, but for basic emission control and diagnostics, the Elise has to support ODB-II.
Some cars put the OBD parameters on both, but most I've seen do not.
16, if you're picky.
The actual ODB-II connector under the dash is a 15 pin connector
OBD-II, ISO Style, is required to be on pins 4/ground, 5/ground, 7/K, 16/pwr -- Pin 15 (L) is optional.
I'm not sure that the pin-outs for all the additional connections are standardized, but they have to be for the ODB-II standard (and most likely the CAN-Bus).
Some (most?) implementations skip the additional L-Line, but the K-Line (Pin 7) is required and it's the one most scantools use. If you have a metal contact at Pin 7, it's 99% certain you have an ISO-9141 OBD-II port and can use any compatible scantool.
HS CANBus is usually (always?) on 6 & 14 when present. While the bus interface is well-defined, the data on it is open to manufacturer whim and I don't yet know what Lotus is pushing out there. Like I said, it could be Beethoven, or it could be Yankee insults.
