1. Description of circuit 
This troubleshooting code is used to 
identify the possible internal faults of 
EBCM.  
 
2. Conditions for setup of 
troubleshooting codes 
DTC C0055 will be set up when there is 
possible fault of internal 
component/microprocessor.  
 
3. Actions to be taken for setup of 
troubleshooting codes 
(1) The electromagnetic relay is turned off 
and pump motor and solenoid are 
disconnected with the power source. ABS 
and DDRP are both disabled;  
(2) Save DTC C0055;  
(3) ABS is disabled and ABS alarm lamp 
is on.  
 

4. Conditions for clearing 
troubleshooting codes 
(1) If the conditions for setting up 
troubleshooting code DTC C0055 are gone, 
corresponding scanning tools can be used 
to clear the troubleshooting code.  
(2) If the troubleshooting code does not 
appear for 100 driving cycles running, it 
can be eliminated from the database.  
 
5. Assistance to troubleshooting 
(1) When C0055 is displayed on the 
scanning device, it shall be followed with 
two digits (XX). They shall be recorded 
along with the other OTC displayed.  
(2) Before making an analysis of C0055, 
please repair the troubles concerning low 
voltage and driving performance or other 
electrical troubles.  
(3) The connection between the EBCM 
and BPMV shall be reliable, fast and free 
of corrosion, leakage and/or damage.

To solenoid valve

From solenoid valve 

This troubleshooting code is used to 
identify the possible internal faults of 
EBCM. When the EBCM relays are 
started (turned on), voltage is provided to 
the valve solenoid and pump motor.  
 
2. Conditions for setup of 
troubleshooting codes 
DTC C0056 is set up when there is 
internal fault.  
 
3. Actions to be taken for setup of 
troubleshooting codes 
(1) ABS alarm lamp is off;   
(2) Save DTC C0056;  
(3) ABS is enabled.  
 
4. Conditions for clearing 
troubleshooting codes 

(1) If the conditions for setting up 
troubleshooting code DTC C0056 are gone, 
corresponding scanning tools can be used 
to clear the troubleshooting code.  
(2) If the troubleshooting code does not 
appear for 100 driving cycles running, it 
can be eliminated from the database.  
 
5. Assistance to troubleshooting 
(1) Before making an analysis of C0056, 
please repair the troubles concerning low 
voltage and driving performance or other 
electrical troubles. 
(2) The connection between the EBCM 
and BPMV shall be reliable, fast and free 
of corrosion, leakage and/or damage. 
(3) DTC C006 is set possibly due to 
troubles of the EBCM relays.

1. Description of circuit 
Application and release of solenoid is an 
inalienable part of EBCM. When the car is 
ignited, the storage battery provides power 
to the solenoid so that the solenoid relay is 
turned on. The EBCM controls the 
solenoid valve through the grounding of 
relevant coil circuit.  
 
2. Conditions for setup of 
troubleshooting codes 
Corresponding troubleshooting codes will 
be set up when the EBCM detects any 
ground fault or solenoid valve short circuit 
to the power source.  
 

3. Actions to be taken for setup of 
troubleshooting codes 
(1) The electromagnetic relay is turned off 
and pump motor and solenoid are 
disconnected with the power source.  
(2) Save the various DTC;  
(3) ABS is disabled and ABS alarm lamp 
is on.  
(4) DDRP is disabled and braking alarm 
lamp is on (only applicable to C0065 and 
C0067).  
 
4. Conditions for clearing 
troubleshooting codes 
(1) If the conditions for setting up 
troubleshooting code DTC C0061 through 
C0068 are gone, corresponding scanning
