Which test is not performed on a 2003 Honda hybrid during an OIS inspection?

During an On-Board Diagnostics (OIS) inspection for a 2003 Honda hybrid, the visible smoke test is not performed because this test is primarily intended for assessing exhaust emissions for traditional gasoline-powered vehicles. The focus of the visible smoke test is to identify any visible emissions that may indicate combustion issues or exhaust leaks, which are less relevant for hybrid vehicles that operate with both gasoline engines and electric motors.

For the hybrid, the OBD II (On-Board Diagnostics II) check is essential as it helps in diagnosing the vehicle's emission control system, reading diagnostic trouble codes, and ensuring that the various components of the vehicle are functioning correctly. Similarly, the malfunction indicator lamp check is crucial for confirming whether the vehicle's onboard systems are detecting issues. Aftermarket parts checks are relevant as well to ensure that any modifications meet the emission regulations. Therefore, since hybrid models do not require visible smoke assessments due to their specific emissions control technology, this makes the visible smoke test the correct answer in this context.
