As long as your Jeep Cherokee does not have an illuminated check engine light and it's been fairly well maintained over the years, it will be able to pass the smog check inspection in California without needing any emission systems modification. Used out of state vehicles which are Federal Emissions certified, such as your Jeep Cherokee, are allowed registration in California with no additional smog components. The same does not apply to new vehicles. Any new vehicle being imported to California must be California Emissions Certified. The underhood emissions label must indicate the vehicle conforms to California emissions requirements.
