Test FC-7D - No Vehicle Speed Sensor Signal

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For appropriate wiring diagram, see WIRING DIAGRAMS  at end of article. rotating wheels.
  1. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect PCM connector terminals. Repair as required. Perform VERIFICATION PROCEDURE VER-2. If PCM connector is okay, go to next step.
  2. Place DRB-II in ohmmeter mode. Using DRB-II, check resistance of PCM connector terminal No. 47, speed sensor signal circuit (White/Orange wire). If resistance is less than 5 ohms, repair short to ground in White/Orange wire. Perform VERIFICATION PROCEDURE VER-2. If resistance is more than 5 ohms, go to next step.
  3. Using an external ohmmeter, check resistance of speed sensor signal circuit (White/Orange wire) between vehicle speed sensor connector and PCM connector terminal No. 47.
  4. If resistance is more than 5 ohms, repair open in White/Orange wire. Perform VERIFICATION PROCEDURE VER-2. If it is less than 5 ohms, replace PCM. Perform VERIFICATION PROCEDURE VER-2.
