Test FC-7B - No Vehicle Speed Sensor Signal

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS  at end of article.
  1. Put DRB-II in ohmmeter mode. Using DRB-II, check resistance of PCM connector terminal No. 47 (White/Orange wire). If resistance is more than 5 ohms, go to step 5). If resistance is less than 5 ohms, disconnect DRL module connector. Using DRB-II, check resistance of PCM connector terminal No. 47 (White/Orange wire).
  2. If resistance is more than 5 ohms, replace DRL module. Perform VERIFICATION PROCEDURE VER-2. If resistance is less than 5 ohms, go to next step.
  3. If vehicle is not an AC body equipped with a mechanical instrument cluster, repair short to ground in White/Orange wire. Perform VERIFICATION PROCEDURE VER-2. If vehicle is an AC body equipped with a mechanical instrument cluster, disconnect Red mechanical instrument cluster connector.
  4. Using DRB-II, check resistance of PCM connector terminal No. 47 (White/Orange wire). If resistance is more than 5 ohms, repair short to ground in mechanical instrument cluster. Perform VERIFICATION PROCEDURE VER-2. If resistance is less than 5 ohms, repair short to ground in White/Orange wire. Perform VERIFICATION PROCEDURE VER-2.
  5. Using an external ohmmeter, check resistance of VSS signal circuit (White/Orange wire) between TCM connector terminal No. 58 and PCM connector terminal No. 47. If resistance is more than 5 ohms, repair open in White/Orange wire. Perform VERIFICATION PROCEDURE VER-2. If resistance is less than 5 ohms, replace PCM. Perform VERIFICATION PROCEDURE VER-2.
