Welcome to the forum. Did you check for any possible trouble codes? Use a digital multimeter, check the voltage circuits at the asd relay. Voltage for the load side of relay, is hot all the time. Voltage for the coil side of relay, goes hot when the key is turned on. The computer grounds the coil side of relay, if it sees an rpm signal.
