DTC Advanced Diagnostics: P0831
DTC P0831:Clutch Pedal Position Switch A Circuit High Voltage

General Description

The power control module (PCM) monitors the clutch pedal position switch A/C (Depress side: CLUTCH SW(SA)) and the clutch pedal position switch B/D (Release side: CLUTCH SW(CRUISE)) signals to switch the starting system from auto control mode to manual mode when it malfunctions. When the PCM cannot detect an OFF signal from clutch pedal position switch A/C (Depress side: CLUTCH SW(SA)) while the clutch pedal is released, the detection continues after the vehicle is turned to the OFF (LOCK) mode. If the malfunction continues for a set time after the vehicle is turned to the OFF (LOCK) mode, the PCM detects a malfunction and stores a DTC.
