If none of the functions can be used, use scan tool to check for any stored DTCs. If any DTCs are stored, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS in appropriate SELF-DIAGNOSTICS article. Then repeat operation. If an incorrect password is input five times in a row, immobilizer-ECU judges that an unauthorized operation is being attempted. Start-prevention mode will be set, and engine operation will stop and all special functions will be disabled. If ignition switch is turned on, and left in that position for approximately 20 minutes, "Unauthorized operation, start- prevention mode" will be cancelled.
