1. Description of circuit
The EBCM controls the orange ABS
alarm lamp through the driver lamp
module incorporated in the instrument
panel.
When the ignition lamp is on, the battery
provides voltage to Terminal ? of the
instrument panel and EBCM Terminal
A11. EBCM Terminals A and B are
always electrified.
Default status refers to the turning on of
the orange ABS module alarm lamp
through the driver lamp module. The
driver lamp module provides the path for
grounding.
When the EBCM instructs the ABS
alarm lamp to turn off, the EBCM will
ground the ABS alarm lamp control
circuit, which will cause the driver lamp
module to provide path for the lamp’s
grounding.
