The pedal module has two independently working sensors (potentiometer or hall effect) for redundancy and plausibility checks. Sensor 2 outputs exactly half the voltage of Sensor 1.
In the original design the DME (Digital Motor Electronics) provides an independent, precision +5V sources for each of the two sensors. It should be noted here that the +5V supply voltage should be precise and stable to assure no erroneous readings from the Inverter Controller.
The Accelerator Pedal Module for manual and automatic gearbox do not differ in their pinout or electrical connector used, so the kickdown switch is probably just a mechanical restrictor. This has to be verified!
