Description Frequency of the PWM signal of the Bosch EDC is smaller than allowed. Effects on the driving operation Hard shifts Possible causes The engine control unit does not match the signal source set in the dataset (see dataset constant: ENG_ECU_TYPE_). The engine control unit delivers a PWM signal outside its specification (engine control unit defective). Place of action No description available. Instruction Verify that dataset and engine control unit match. Make corrections if required. Setting conditions of the event No description available. Test conditions of the event No description available. Final function check If the defective component cannot be clearly identified, you should try to reproduce the fault: Reinstall the component in the vehicle. Test the function. After the fault has been eliminated, the following steps have to be carried out: Conduct a test drive with function check. Read out the fault memory. Check the transmission for leaks. Perform a final visual inspection. These steps are necessary to ensure the entire vehicle functions. See also:
