Test point 2
Body ground


Is there continuity?

     
YES
     
     
     
Repair a short in the CLUTCH SW(SA) wire between the PCM (A21) and clutch pedal position switch A.?
     
NO
     
     
     
The CLUTCH SW(SA) wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM, then recheck. If DTC P0831 goes away and the PCM was substituted, replace the original PCM.?
