If your OBD module was previously working but suddenly stops displaying data on the CHIGEE Display — especially after your motorcycle has been parked for a while or has experienced a fault — there are a few key steps to check.
Step 1: Confirm OBD Module Connection
Check the indicator light on the OBD module:
Flashing blue light: The module is connected to the CHIGEE Display. This does not necessarily mean that motorcycle ECU data is being successfully read.
Flashing red light: The module is disconnected or not transmitting data properly
Step 2: Motorcycle-Side Check
A flashing blue light confirms the display connection, but it does not rule out a module or communication fault. Check the module, pairing, power supply and diagnostic connector. Also inspect your motorcycle for recent electrical issues, ECU errors or power-related faults that may prevent the OBD interface from transmitting data.
Some common causes:
Motorcycle battery voltage instability
ECU protection or fault modes
Loose or corroded OBD port connection
