Question

A customer states her MIL is blinking. Technician A says that this condition may damage the catalytic converter if the customer continues driving. Technician B says that freeze frame data should be stored. Which technician is correct?

Answer 1

Both Technician A and Technician B are correct. Continuing to drive with a blinking MIL can damage the catalytic converter, and freeze frame data should be stored.

Step-by-step explanation:

Both Technician A and Technician B have made correct statements regarding the customer's blinking MIL (Malfunction Indicator Light). The MIL is also known as the 'Check Engine' light, which is designed to indicate potential issues with the vehicle's engine or emissions system.

Technician A is correct in stating that continuously driving with a blinking MIL can potentially damage the catalytic converter. This is because a blinking MIL usually indicates a severe engine misfire, which can send unburned fuel into the catalytic converter and cause it to overheat.

Technician B is also correct in recommending the storage of freeze frame data. Freeze frame data captures a snapshot of the vehicle's parameters at the time the MIL was triggered. This data can be useful for diagnosing the specific issue that caused the MIL to illuminate.
