![]() With the aid of some emission packages, the ASD relay provides a 12+ volt power to the oxygen sensor heater relay and sensor heating elements of the vehicle. Therefore, when the vehicle’s engine is then turned off, the ASD relay shuts down all of its activities immediately as a preventive measure to safeguard other engine components and the whole vehicle. When the vehicle’s engine is immediately up and running the automatic shutdown relay kicks off too, supplying a switched power of 12+ volts to the ignition coil and fuel injectors this helps to allow the smooth operation of the engine system. Voltage is being supplied to the remaining part of the circuit by terminal number 87. When the fuel pump and automatic shutdown relay are powered by the powertrain control module (PCM), terminal number 30 connects to terminal 87 in an on position.The rest of the circuit is not being supplied with power.Terminal 30 is being connected to terminal 87A in an off position. The powertrain control module stops the function of the fuel pump and ASD relay.Voltage is being supplied to the coil side of the ASD relay by terminal 86. ![]()
