when either a grounding switch is closed or one of the pertinent modules provides a path to ground for that indicator. The driver information display
does not perform any self-tests or diagnostics and is used only as a communication device for the driver.

The Powertrain Control Module (PCM) will determine the amount of oil life from various sensors and inputs within the engine control system. When the
PCM has determined that an oil life of 0 percent is present it will inform the driver by turning on the CHANGE OIL SOON indicator by supplying
ground to circuit 803.
