    Write a function that analyzes a vehicle's diagnostic code, where each digit represents a maintenance parameter threshold, and verify that no parameter threshold appears more times than its own value to ensure safe operation conditions. For example, if a parameter threshold is represented by digit 3, it should not appear more than 3 times in the diagnostic code.
