alarm lamp through the
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

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
