The TCAN1162-Q1 family of devices have the transceiver status (TS) pin that indicates any faults detected by the transceiver. This pin goes low when a fault is detected; otherwise, it is a logic high. The TCAN1162EVM has an LED connected to the TS pin which illuminates when the TS pin goes low. The J6 jumper must be shunted for this LED to work; otherwise, it will not be connected to the TS pin. Please see the TCAN1162x-Q1 datasheet for more information on the faults detected by the TCAN1162-Q1 family of devices, and what the TS pin indicates specifically.
