California Smog Check Inspector Practice Test

What action should be taken if there is a damaged harmonic balancer during an ignition timing functional test?

1. Proceed with the inspection without noting the defect

2. Record the damage and cancel the inspection

3. Ignore the defect and continue testing

4. Stop the test and address the damage

The correct answer is: Stop the test and address the damage

When a damaged harmonic balancer is discovered during an ignition timing functional test, it is critical to stop the test and address the damage. The harmonic balancer plays an essential role in the engine's operation by dampening vibrations and helping to maintain the timing of the engine's components. If it is damaged, it can lead to further complications, including inaccurate ignition timing, which may result in poor engine performance, increased emissions, and potential damage to other engine parts. By stopping the test, the inspector ensures that any underlying issues caused by the damaged harmonic balancer can be properly assessed and corrected before further testing or inspection activities proceed. Continuing the test without addressing the defect could result in misleading data and allow an improperly functioning vehicle to pass the inspection, which goes against the objectives of the smog check program to minimize emissions and promote vehicle safety and reliability. Therefore, recognizing and addressing the damage is vital for both the integrity of the inspection process and the environmental standards set by California law.
