module incorporated in the instrument
panel.
When the ignition lamp is on, the battery
provides
instrument panel and EBCM Terminal
A11. EBCM Terminals A and B are
always electrified.
Default status refers to the turning on of
the braking system m
through the driver lamp module. The
driver lamp module provides the path for
grounding.
When the EBCM instructs the braking
indicator la
will ground the braking alarm lamp
control circuit, which will cause the

When the ignition switch is on, the
EBCM will turn on the braking alarm
lamp for three secon
Once any normal braking system or
DDRP system trouble is detected, the
EBCM will turn on the braking alarm
lamp to inform the driver the necessity
to repair the braking system or DDRP
system.
2. Assistance to troubleshooting
The typical causes of the failure of
braking
troubleshooting codes include:
(1) Lamp trouble/socket bad contact
(2) Broken fuse on instrument panel
(3) Instrument/driver lamp
trouble
(4) EBCM trouble
