This is the Off position. In the off position, voltage is not supplied to the rest of the circuit. Terminal 87A is the center terminal on the relay. When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30. Jeep ASD relay magic or not? Automatic Shut Down relay It cuts fuel (and spark) if the PCM thinks, there is any danger of crash and burn. The PCM drops the ASD relay for many reasons, this list is for all years. (some methods, are missing on early years) Any scan tool will show DTC errors for each failure cranking or running (SCAN it LOOK) Lost 12 volt DC electric power.
