Abstract
A method of operating an electronic control module disposed on a vehicle and operative to record in a memory a plurality of data items among a plurality of pages, and a computer program for execution by the electronic control module are disclosed. The plurality of data items include at least one event item and at least one accumulation item for the vehicle. In operation, recording of the at least one event item is disabled in a selected page of a plurality of pages in response to receiving a stop recording page signal associated with the selected page. All event items and all accumulation items for the selected page are then erased to eliminate historical data. Subsequent accumulation items may then be recorded in the selected page. Synchronization of the accumulation items and event items is re-established by erasing all historical accumulation items from the selected page when the selected page recording is reenabled.
