change ranges from 11.0 V to 15.5 V. Control signal is sent to L
terminal
C
(Communication) Voltage regulator input to control engine
operation block. Japanese cars
GC

RLO
(Regulated Load Output) Input to control stabilizing voltage
from 11,8 to 15 V (TOYOTA)
COM
(Communication) General term for physical interface,
alternator control and diagnostics. Protocols of use: BSD (Bit
Serial Device), BSS (Bit Syn- chronized Signal) or LIN (Local
Interconnect Network)
LIN
Direct indication on control interface and alternator
diagnostics, con- ducted under LIN protocol (Local
Interconnect Network)
DF
