Please Check Your App/ Peripherals

Description: "Please check your app/ peripherals" error is a communication error and means that the display and the controller cannot establish a connection.

Symptoms: "Please check your app and Peripherals" or "Display/Controller Error" on the SW102/ DS103 display and/or on the Ride Control app. This is often paired with the battery level indicator on the display flashing.

Please note that the controller would automatically be in Street mode, assist level 3 if there is such an error.  The motor would still be able to run in such a condition.

Solution: Ensure the display and the 1T1, 1T2, or 1T4 wiring harness is properly connected. Check the display and either replace the wiring harness, display, or controller.

Steps:

1. Inspect the 1T2, 1T2, or 1T4 connectors especially the pins to check for any damage and bent pins.
   Checking for bent pins or if pins may have been bent and bent back is crucial as this is could result in the error. You need to inspect the female side of the connectors as well for dents as this is an indication that the connectors were forced in. If there are signs that the pins or connectors are damaged, replace the wiring harness only. Otherwise, continue to step 2. 
2. If you have another CYC kit or have sufficient additional spare parts, swap out the display to see if the error goes away with the other display. You can also swap out the wiring harness. If you can locate the issue by swapping out components, then you can report your findings directly to CYC or an Authorised 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 3 below.
   
   WARNING: The below steps should be exercised with care. Mistakes may cause additional issues. You may choose to send your components to CYC or an Authorised Reseller for testing instead.
   
   
3. Unplug the display and short-circuit the B+ & Key-In pins using a Dupont wire. See the diagram below for reference.
4. Attempt to connect to the CYC Ride Control app. 
5. Lift the rear wheel and press in the throttle. 
   *WARNING: Lift the rear wheel BEFORE attempting to press the throttle as the system will be in the highest assist level by default. 
6. If the motor does not function with the Dupont wire, and the wiring harness has also been checked, replace the controller by following the guidelines in the article below:

Warranty condition: If the motor in question is still within its warranty period and there is no indication that the motor has been altered physically (such as cutting wires), then the components needed will be replaced under warranty. 

*Wiring or connection damage as a result of bent pins or damaged connectors will NOT be warranted.
