3.1.9 Pin 8 of the 14-Pin Transceiver

Pin 8 of the 14-Pin transceiver is normally a status indicator flag (nFAULT) or a SPI clock pin (SCLK). The signal path to the J1 header connects to diode D2, signifying whether pin 8 is high or low. Note that the diode is inverted and the nFault LED D2 lights up when a fault is present or when the 14-pin device is disconnected (nFault is floating).
