15PG2 - Photon Gen 2: Display Dead on Arrival


Checklist

  1. Ensure that you are pressing the display's power button for at least 3 seconds before releasing
  2. Unplug the display and the wiring harness and check the connectors at both the display-harness and the controller-harness points. 
    1. *The pins on the connectors need to be inspected carefully as any pins that are bent or have moved from their original position, can cause issues. 
    2. CYC or an authorized Reseller may ask you for evidence showing that your connector pins are still in good condition. 
  4. Ensure there are no wires that are pinched in or bent flat that could be obstructing the signal or damaging the cables. 
    1. *It's best to check the system with the wiring harness and cables freely moving i.e. not tied onto your bike frame directly.
  6. Ensure that your battery is fully charged and in good condition.
    1. *You can use a voltmeter or multimeter to check that your battery is not corrupted. 


Troubleshooting Steps

If you have completed the above checklist, proved that your connector pins are in good condition, and you still cannot find a cause for the kit not turning on, confirm the following: 

  1. If you have another CYC kit or have sufficient additional spare parts, swap out the display to see if the display works on the other system. You can also swap out the controller and wiring harness respectively. If you can locate the issue by swapping out components, then you can report your findings directly to CYC or an uthorised reseller to organize a replacement (i.e. you do not need to continue troubleshooting). 
    *If you do not have any spare parts, continue to step 2 below.
  2. Perform a display bypass test: ðŸ“„ Display Bypass Test

WARNING: Lift the rear wheel BEFORE attempting to press the throttle, as the system will be in the highest assist level by default. 

Solution


1. Replace the display

With the B+ and Key-in pins connected, if you can connect to the Ride Control app and your throttle is outputting power when pressed down, then the display has failed and needs to be replaced.


2. Replace the controller

With the B+ and Key-in pins connected, it is likely a controller issue if you cannot connect to the Ride Control app and your throttle is not outputting any power when pressed down. Replace the controller accordingly.


3. Replace torque sensor/ motor/ speed sensors 

If the issue is resolved by disconnecting the sensor, then replace that part.
