  1. Turn ignition off. Disconnect VSS connector. Inspect vehicle speed sensor connector for damaged or pushed out terminals. Repair as necessary. Perform TEST VER-2. If VSS connector terminals are okay, go to next step.
  2. Turn ignition on. Put scan tool in voltmeter mode. Using scan tool, check voltage on VSS connector White/Orange wire. If voltage is less than 4 volts, go to TEST TC-11D.
  3. If voltage is more than 4 volts, connect a jumper wire to VSS connector White/Orange wire. Using scan tool, read VSS signal. While observing scan tool display, touch other end of jumper wire to VSS connector Black/Light Blue wire. If scan tool displayed more than zero MPH, go to next step. If scan tool did not display more than zero MPH, go to TEST TC-11E.
