Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P080800

Condition
Engine control module (ECM) monitors the clutch pedal's movement and position using a position sensor (1) and a position switch (2). The position sensor is connected to the Central electronic module (CEM) and information is sent to the Engine control module (ECM) via CAN. The position switch is directly connected to Engine control module (ECM) and is open (clutch pedal let up) in its starting position. When the clutch pedal is pressed down by more than 75%, the contact closes.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The clutch pedal position switch is closed (active) for a certain amount of time, without the position sensor indicating that the clutch pedal has been depressed.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Constant vehicle speed.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.





Substitute value
- None.

Possible source
- Incorrectly installed or sticking position sensor or position switch.
- Contact resistance, oxidation or loose connections in the connectors.
- Some of the sensors have a short-circuit to ground.
- Incorrect position switch or position sensor.

Fault symptom[s]
- Starting/Autostart does not work
- Cruise control/Disengagement does not work
