Park/Neutral Relay (Q45)

ECM applies and monitors voltage to park/neutral relay on ECM terminal No. 44. When gear selector lever is in Park or Neutral position, relay is supplied voltage through selector switch. When relay is energized, contacts inside relay close, pulling voltage on ECM monitored circuit (terminal No. 44) low. This is interpreted by ECM as a park or neutral signal.
