How we checked it
- We start from ECUMaster's pinout document for this ECU.
- Every pin is read again in a second ECUMaster document: the compact pinout sheet, the user manual or, for pins that are the same on a sister ECU, that ECU's pinout. Where no second document lists a pin, we read it a second time by eye from the same pinout.
- A pin is only shown when both readings give the same function. ECUMaster's documents name no wire colours, so none are shown.
- Notes are ECUMaster's own descriptions from its pinout.
