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.
- Place DRB-II in ohmmeter mode. Using DRB-II, check resistance of Powertrain Control Module (PCM) connector terminal No. 47, speed sensor signal wire (White/Orange wire). If resistance is more than 5 ohms, go to step 4).
- If resistance is less than 5 ohms, disconnect Daytime Running Light (DRL) module. Using DRB-II, check resistance of PCM connector terminal No. 47, speed sensor signal wire (White/Orange wire). If resistance is more than 5 ohms, replace DRL module. Perform TEST VER-2.
- If resistance is less than 5 ohms, repair speed sensor signal wire for short to ground. Perform TEST VER-2.
- If resistance was more than 5 ohms in step 1), use an external ohmmeter to check resistance of speed sensor signal wire (White/Orange wire) between PCM connector terminal No. 47 and transmission control module connector terminal No. 58.
- If resistance is more than 5 ohms, repair open speed sensor signal wire. Perform TEST VER-2. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2.
