Unit
CLUTCH PEDAL POSITION SWITCH A
CLOSE
      

Do the current condition(s) match the threshold?

     
YES
     
     
     
The failure is duplicated. Go to step 2.
     
NO
     
     
     
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at clutch pedal position switch A/C and the PCM, and check the installation of clutch pedal position switch A/C. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.?
2.
Clutch pedal position switch A installation check:

Is it damaged or loose?

     
YES
     
     
     
     
NO
     
     
     
Go to step 3.

Shorted wire check (CLUTCH SW(SA) line):

Shorted wire check (CLUTCH SW(SA) line)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Jump the SCS line with the HDS.


?3.
Disconnect the following connector.
PCM connector A (51P)

?4.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
 
Clutch pedal position switch A/C 4P connector: disconnected
 
PCM connector A (51P): disconnected
Test point 1
Clutch pedal position switch A/C 4P connector No. 4
Test point 2
Body ground


Is there continuity?

     
YES
     
     
     
Repair a short in the CLUTCH SW(SA) wire between clutch pedal position switch A/C and PCM (A10).?
     
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.?
