26 Hybrids Vehicles

27 Presumably P3005 would also be recorded if an attempt was made to start up with the service plug

removed, as the high voltage fuse is physically located inside the plug.

28 P3006 - not too sure about this, but criterion appears to be maximum permitted difference between

highest block voltage and lowest block voltage at any instant (not including transients) is 1.2 volts.

29 P3009 - "Leak detected", meaning a current leakage path the high voltage circuitry to the chassis has been

detected. Trigger level not known, but the criterion for manual testing is insulation resistance not less than

10M ohms when tested at 500V DC.

30 The traction battery consists of 38 physical modules, each containing 6 cells. For the purposes of

monitoring by the battery ECU, modules are paired into 19 "blocks". DTCs P3011 to P3029 appear to

indicate the "malfunction" of a particular block, although what "malfunction" means is not clear.

31 P3030 - presumably means open circuit of one of the twenty voltage sense lines which are connected to

the cell string at the ends and between each block.
