Test 74A - Engine Node No Response

NOTE: For connector terminal identification, see CONNECTOR  IDENTIFICATION. For wiring diagram, see WIRING DIAGRAMS  . Perform TEST VER-1 after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Turn ignition switch to OFF position. Disconnect engine node connector. Engine node is located on inner front bumper. Check, clean and repair connections as needed. Ensure courtesy lamps are off. Close all doors and wait one minute. Go to next step.
  2. Put DRB in ohmmeter mode. Measure resistance at engine node connector terminal No. 1 (Black/Light Green wire). If resistance is more than 5 ohms, repair open Black/Light Green wire. If resistance is less than 5 ohms, go to next step.
  3. Turn ignition switch to ON position. Put DRB in voltmeter mode. Measure voltage at engine node connector terminal No. 11 (Dark Blue/White wire). If voltage is less than 10 volts, repair open in Dark Blue/White wire. If voltage is more than 10 volts, go to next step.
  4. Using an external ohmmeter, measure resistance of Violet/Brown wire between engine node connector terminal No. 7 and Data Link Connector (DLC) terminal No. 7. If resistance is more than 5 ohms, repair open Violet/Brown wire. If resistance is less than 5 ohms, go to next step.
  5. Measure resistance of White/Black wire between engine node connector terminal No. 8 and DLC connector terminal No. 3. If resistance is more than 5 ohms, repair open White/Black wire. If resistance is less than 5 ohms, replace engine node.
