ECU IDENTIFICATION
Displays the part number of the inverter (front).
This is an on-board trouble diagnosis system which automatically detects malfunction. Detected malfunction is memorized in ECU as DTC. Diagnosis information can be confirmed using CONSULT.
DTC (P0A1B, P0A2A, P0A3F, etc.) are specified by SAE 2012/ISO 15031-6.
Inverter (front) memorizes DTC and freeze frame data when malfunction is detected.
Freeze frame data stored first and freeze frame data stored last remain for each DTC. Therefore, when occurring 3 times or more, the data in the middle do not remain.
Counter system counts up at every operation of power switch from OFF to ON under condition that the same malfunction is not detected. On the other hand, if the same DTC as memorized one is detected again, the count is reset and the counter system counts up again from “0”.
