DTC Advanced Diagnostics: P0835
DTC P0835:Clutch Pedal Position Switch B Circuit Low Voltage

General Description

The powertrain 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 ON signal from clutch pedal position switch B/D (Release side: CLUTCH SW(CRUISE)) 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.

[ ]: HDS Parameter

Malfunction Threshold
The PCM cannot detect an ON signal from clutch pedal position switch B/D (Release side: CLUTCH SW(CRUISE)) for at least 30 minutes after the vehicle is turned to the OFF (LOCK) mode.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
Clutch pedal position switch B/D (Release side: CLUTCH SW(CRUISE)) OFF failure
Clutch pedal position switch B/D (Release side: CLUTCH SW(CRUISE)) CLUTCH SWITCH(CRUISE) line open

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, a Confirmed DTC and the freeze data are stored. The MIL does not come on.

Conditions for clearing the DTC
The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
