Navigation System Will Not Accept Security Code

Navigation system will not accept security code

NOTE:
- The system will not operate without the 4-digit security (anti-theft) code. Follow the this procedure. (After 10 consecutive tries, you must cycle the key to continue trying)
- The Navigation System Diagnosis and Core Return Form is available online, under Job aids and can be printed out for recording this information. This information will help the Reman facility determine what caused the failure.
- Check for and resolve all CAN DTCs before troubleshooting the navigation system.
- Check the connectors for poor connections or loose terminals.
- Before troubleshooting, make sure you have the anti-theft codes for the navigation system.
- Verify that the correct navigation unit is installed for this model. Go into the Diagnostic mode and use Version.
- Make sure that the correct DVD color and version are installed.
- Check any official Honda service website for more service information about the navigation system.
- Check the vehicle battery condition first.

Is the serial number displayed?

YES - Go to step 2.

NO - Replace the navigation unit.

2. Obtain the Serial Number (3 letters followed by 8 numbers) from the label on the underside of the navigation unit (not the display unit). Using the Serial Number, look up the navigation security code in the Interactive Network, (click: Service, Vehicle Information, Anti-Theft code Inquiry, and then select Navigation from the product dropdown box). Enter the serial number.

Is a 4-digit code displayed?

3. Check the obtained code work to bypass the code screen.

Does the code work?

YES - The system is OK at this time.

NO - Go to step 4.

YES - Replace the control unit, and enter Security code is 0000 in the problem description field of the core return form.

NO - Replace the control unit, and enter Won't take security code (as proof, enclose the sticker that contains the Serial number and the Code) in the problem description field of the core return form.
