- Diagnostic Trouble Codes (DTC) for which the MIL is switched on by the engine control module immediately after a malfunction is recognized are identified with the MIL switching condition "immediately."
- Diagnostic Trouble Codes (DTC) for which the MIL is not switched on until the malfunction is recognized after taking 2 trips are identified with the MIL switching condition "2 Trips."
