MIL Bulb Check and Readiness Code Condition

When the ignition switch is turned to ON (II), or 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. 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.
