MIL Bulb Check and Readiness Code Condition
When the engine start/stop button is pressed to select the ON mode, the PCM turns on the MIL via the F-CAN circuit for about 15 to 20 seconds to check the bulb condition. USA and Canada models: If any readiness codes are not set to complete, the MIL flashes five times. If all readiness codes are set to complete, the MIL goes off.
