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.
- Using VIDA vehicle communication, check that the parameter "Clutch pedal position (%)" changes its value when the clutch pedal is depressed. The value should drop when the pedal is depressed. Note the value indicated when the pedal is released.
- Start the vehicle. Check which value is indicate when the vehicle is held in traction mode, i. E. when with a gear engaged, the clutch is released just enough for the vehicle to start attempting movement. Come this value to the value indicated when the clutch pedal was released. If the difference is more than 10%, the clutch pedal position sensor is working and correctly installed. If the difference is less than 10%, check that the sensor is OK, correctly installed and whether there is something that affects the traction position.
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.

Caution: In order for Electronic throttle module (ETM) to reset any reconfigurations as well as delete internally stored problems, the following must be performed:
- Ignition off, wait three minutes so that the main relay / system relay releases the voltage feed to, among other, Electronic throttle module (ETM).
- Then turn on the ignition and turn it off again.
- Wait another three minutes. If the electric cooling fan is running, you have to wait another two minutes after the electric cooling fan has stopped, to make sure that Electronic throttle module (ETM) has been shut off correctly.
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.
