Deutz-Fahr 91: Cable Break or Short Circuit in Digital Pedal Circuit

The fault code indicates a problem with the cable associated with the digital pedal, specifically a break or short circuit. It also points to an issue with the pulse width modulation (PWM) signal range or frequency.

1. 1

   Cable integrity

2. 2

   Connection points of the digital pedal

3. 3

   Signal output from the digital pedal

1. 1

   Inspect the cable for visible damage or breaks

   Check the entire length of the cable for cuts, fraying, or other physical damage.

2. 2

   Test for continuity and resistance

   Use a multimeter to test the cable for continuity and resistance to identify any short circuits.

3. 3

   Verify the PWM signal from the digital pedal

   Use an oscilloscope or multimeter to check the PWM signal range and frequency for proper operation.
