5.1. Scanner Does Not Power On

• Ensure the OBDII cable is securely connected to both the scanner and the vehicle's DLC.
• Verify that the vehicle's ignition is in the "ON" position (engine off or running).
• Check the vehicle's fuse for the OBDII port.

5.2. Link Error / Communication Error

• Confirm the vehicle supports the OBDII protocol (most vehicles from 1996 onwards do).
• Ensure the ignition is "ON" and the cable connection is secure.
• Try connecting the scanner to a different OBDII-compliant vehicle to rule out a scanner issue.

5.3. Codes Do Not Clear

• The underlying issue causing the DTC must be resolved before the code can be permanently cleared. Clearing a code without fixing the problem will result in the code reappearing.
• Ensure the ignition is "ON" (engine off) when attempting to clear codes.
