We have found a bit of a misprint in the pinout. 5V A on connectors A and B registers as 5vB in the ECU. 5v B on connector C registers as 5vA in the ECU.
We noticed this on an ecu that would not provide voltage to the cam and crank sensors, which were wired to 5v A according to the pinout but the ECU shows 5vB with a fault. All other sensors that are on 5vB according to pinout have 5v and are working as 5vA in the ecu shows it is supplying 5v.
