B+ 30
[QUOTE=glennlindh;24774704]And mine is automatic, so how do I press a clutch pedal?? Just saying!! [/QUOTE
You may be showing your problem on your Fluke meter.
Terminal 30 isn't just from battery to starter and fuse panel. Terminal 30 is Battery (+) throughout the car. In other words any terminal 30 should have full battery voltage.
I haven't looked at the etm to see if any tcu terminal is B+, but assume the wire you are checking being red, should be B+ or 13.5 volts or more. You show only 8.0 which is a huge voltage drop unless your battery is dead.
I think you are on the right track since you show low voltage and scan says B+ is missing. You need battery voltage in that wire.

Thanks for reply
Thu, me and the Bentley does not go together, I tried to find out what cable that support the TCU harness the 12v, but I can't find the color/cable..
If/then I "jump" the harness with direct 12v it does not help my issue..
It is still same problems..
18034 - Powertrain Data Bus
P1626 - 35-00 - Missing Message from TCU
18010 - Power Supply Terminal 30
P1602 - 35-00 - Voltage too Low

Ohh I forgot, the connection station under the left kick panel, fuses etc.. they are all 12v, and my battery is new, and charger still connected..
