E-14 Diagnosis and Cross Exchange

Pointer

After the cross exchange, please fill out the "E-14 warranty claim" section in our online service form and use it to inform us of your results: Which component have you identified as defective? What else did you find out?

Checking the Shifter Unit

  • Install eBike battery and switch eBike system 'ON'
  • E-14 Diagnostic Shifter Unit
    • "peeps" when eBike system is switched on and shifts through all gears: Original E-14 Shifter Unit is faulty
    • does not "peep" when eBike system is switched on and does not shift through all gears: Next Step = check the Handlebar Switch Unit
    • "peeps" when eBike system is switched on but does not shift through all gears: Next Step = check the Handlebar Switch Unit

Do not disconnect the E-14 Diagnostic Shifter Unit, before completing the next step.
