Checking components

Check whether the engine control module (ECM) has stored any diagnostic trouble code that indicates a fault in the clutch pedal position sensor. If, for example, diagnostic trouble code ECM-9300 is stored in the engine control module (ECM), it indicates that the engine control module (ECM) detected an electrical fault in the clutch pedal position sensor. This trouble code should be fault traced first. Otherwise, continue as follows.

Use the diagnostic trouble code's frozen values and the counter to determine if the fault may have been stored at the same time. The values show the problem's current status and how intermittent the problem is.

HINT: Using VIDA vehicle communication, check that the parameters "Clutch pedal position (%)" and "Clutch pedal position sensor (V)" indicate correct values. To aid fault tracing, use Component specifications when measuring and checking relevant components and use Wiring diagram, Signal description and Breakout box to measure and control signals to and front the control module or its components. 

Check the installation and function of the clutch pedal sensor.

Remedy as necessary.

Other information 

Caution: In order for Electronic throttle module (ETM) to reset any reconfigurations as well as delete internally stored problems, the following must be performed:

If this is not done correctly, diagnostic trouble codes may remain even after deleting diagnostic trouble codes and any reconfiguration may remain, despite the problem being fixed.
