Michael,

What is your model year and your derived chassis number? [See: SZ Series Shorthand Chassis Derivation]

My gut tells me it has to be OBD-II, as those cars are later than original OBD and prior to CAN.

Michael,

I cannot make heads or tails out of the VIN you supplied. There is no Bentley model that I know of that should have a 'P' in the fifth position. Nor do I know what you're describing as an "RT." If the fifth position is a Z then you have a Bentley Continental SC. If the 'W' is correct in the 10th position of the VIN your car is a 1998.

Once OBD became the standard so did the connector for same. The round connector you describe sounds like the old RR-Bentley specific MasterCheck connection, but these were long gone by 1998.

Brian, confused

Yes in the US it was but not in the UK it stayed as master check
and runs ZYTEC

Michael,

Interesting.

You've introduced me to a model that I had been unaware of, the Bentley Turbo RT. I've updated my shorthand chassis number derivation table such that 'P' in position 5 denotes a Turbo RT. Since their production numbers were so small and they were only made for two years I'd never encountered one. Based on the information in IETIS/TSD6000 you have a long wheelbase Turbo RT.

Good luck in finding out what the pin-out configuration is on the diagnostic connector you have. I can find nothing in IETIS that documents what each of the 48-pins in the MasterCheck connector does. It would be most helpful to post whatever information you do end up finding.

Brian

A very well-informed birdy tells me that this information remains a very well-kept secret. There may, however, be someone on the RROC-Australia Discussion Forums who's been doing some digging into this.

I would suggest you post there. You'll see another of our regulars here is now posting there, too.

Hi,
about the TSD 6000 for the round Diagnostic plug ;
- the K & L lines are on v & w pins
- but they are also on the r & s pin with the electrical diagram

On my 97 UK turboR i haven't v & w but i have r & s . Are they correctly wired, that's the Shakespear's question .... ?








Would you, please, excuse my bad English, I'm just french. Nobody's perfect ....
