   Is there continuity?

   YES 

   Repair a short in the CLUTCH SW (SA) wire between the PCM (A18) and clutch pedal position switch A.

   NO 

   The CLUTCH SW (SA) wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM , then recheck. If DTC P0831 goes away and the PCM was updated, troubleshooting is complete. If DTC P0831 goes away and the PCM was substituted, replace the original PCM .
