April 5, 2026: LEMON Manuals is launched! Read the announcement.

Phone Module (PHM) (2009-12)

All the values given below are between the respective terminal in column 1 and terminal #C1-6 in column 2 (power ground) unless otherwise stated in parenthesis after the table entry.

NOTE: It is important to connect the breakout box and check the ground connections before starting to measure.

There may be several connections and connectors between the control module and components.

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 as a %	-	-
