Signal Specification

General

All the values given below are between the terminals stated in column 1 and terminal #A:6 in column 2 (power ground). This applies unless otherwise indicated in brackets.

NOTE:

It is important to connect the breakout box and check the ground terminals before taking readings.

There may be several connections and connectors between the control module and components. For more information about these, see relevant section in Wiring diagram.

U=	DC voltage in volts (V)	U_AC =	AC voltage in volts (V)
U_bat =	Battery voltage (V)	f =	Frequency in Hertz (Hz)
U_low =	Voltage approximately 0 V	t =	Time in seconds
PWM =	Pulse-width modulated signal in %
