If red or green lights that are on the control unit D4P blink, an error in one of the system sensors. An error may be due to 2 reasons:
- The sensor is not connected to the sensor wiring. Check the connection or the fault sensor to the sensor wire and also to the between sensor and extensión wires.
- The sensor is defective. This problem is very difficult to occur because the sensors are checked 2 times before selling, but it may be the case party has during installation if not installed properly.
If the LED flashes 4 times, it is likely that the wiring is not connected, as by default D4P first reports of the absence or disconnection of sensor-order (4) and then progressively as it is finding successive 3, 2, 1.
