Input Test/Replacement

Input Test/Replacement

1. 3 – P connector
2. mounting bolt
3. VSS
4. Drive link
5. Disconnect the 3 – P connector from the vehicle speed sensor (VSS).
6. Check for continuity between the BLK terminal and body earth.
   • If there is continuity, go to step 3.
   • If there is no continuity, check for:
     • poor earth (G301),
     • an open in the wire.
7. Check for voltage between the YEL terminal and body earth with the ignition switch ON.
   • If there is battery voltage, go to step 4.
   • If there is no voltage, check for:
     • blown No. 8 (10 A) fuse in the passenger compartment fuse/relay box,
     • an open in the wire.
8. Check for voltage between the ORN terminal and body earth with the ignition switch ON.
   • If there is 4 – 6 V, go to step 5.
   • If voltage is not 4 – 6 V, check for:
     • faulty speeds/odo/trip meter drive circuit (C7 terminal of the gauge),
     • an open in the wire.
9. If all the input tests prove OK, but the speeds/odo/trip meter does not work, remove the two mounting bolts and replace the VSS.
