DTC Advanced Diagnostics: P1703
DTC P1703:Clutch Switch Incorrect Correlation

General Description

The powertrain control module (PCM) monitors clutch pedal position switch A/C and clutch pedal position switch B/D. If either of clutch pedal position switch stuck on/off failure occurs, the PCM performs the correlative abnormality detection of the clutch pedal position switches. If the input signals from the clutch pedal position switches are improper while the vehicle is running, the PCM starts the malfunction detection after the vehicle is turned to the OFF (LOCK) mode. If the signal from the clutch pedal position switches are abnormal for a set time, the PCM detects a malfunction and stores a DTC.

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.
