1st Trip Detection Logic and Two Trip Detection Logic

DIAGNOSIS SYSTEM (HPCM)

DIAGNOSIS DESCRIPTION : 1st Trip Detection Logic and Two Trip Detection Logic

When a malfunction is detected for the first time in two trip detection logic, 1st trip DTC and 1st trip freeze frame data are stored in the HPCM memory. The MIL does not illuminate at this stage. There are diagnoses that illuminate the hybrid system warning lamp and/or the 12-volt battery charge warning lamp, and others that do not illuminate them. [1st trip]
If the same malfunction is detected again during the next drive, the DTC and freeze frame data are stored in the HPCM memory, and the MIL, hybrid system warning lamp and/or the 12V battery charge indicator lamp illuminates. The MIL illuminates at the same time when the DTC is stored. [2nd trip]
The "trip" in the "two trip detection logic" means a driving mode in which self-diagnosis is performed during vehicle operation.
Some diagnoses of the two trip detection logic may illuminate the MIL, the hybrid system warning lamp and/or
12-volt battery charge warning lamp and others may not.
When a malfunction is detected for the first time in one trip detection logic, the DTC and Freeze Frame data are stored in the HPCM memory. There are diagnoses that illuminate the MIL, the hybrid system warning lamp and/or the 12-volt battery charge warning lamp, and others that do not illuminate them.
