Question

what should be done if the oil change indicator displays reset cancelled? a) a scan tool must be used to access the pcm. b) the reset process should be repeated. c) the oil must be changed. d) nothing, this is the expected message.

Explanation:

When the oil - change indicator displays "Reset Cancelled", the reset process likely needs to be repeated to properly reset the indicator. Using a scan tool to access the PCM is not the first - step action for this specific message. Changing the oil is not directly related to this display message. And it is not an expected message with no action required.

Answer:

B) The reset process should be repeated.
