C1111 INFINITI, NISSAN: ABS PUMP MOTOR
The Anti-lock Braking System (ABS) is used to prevent the wheels from locking or losing traction during braking. It works in conjunction with the traditional braking system. The ABS has a built-in pump that is connected to the circuits that control the brake fluid and wheel revolutions. If after performing hard braking one of the wheels tends to slow down, which can result in a lock-up, the system will reduce the pressure on the brakes. Therefore, driver intervention will not be necessary.
The ABS pump creates a return of the brake fluid stored in the master cylinder reservoir. This action causes a decrease in the brake pressure. In turn, the motor activates the pump, taking into account the signals provided by the ABS Actuator and the Electrical Unit (Control Unit).
The DTC C1111 OBD2 is a code that signals a fault in the ABS Pump Motor. It is set when the engine shuts down during engine operation and the actuator is on. It is also set when the control line for the engine relay is open.
