DESCRIPTION
CONSULT-III performs the following functions via CAN communication with ADAS control unit and the com-
munication with accelerator pedal actuator.
SELF DIAGNOSTIC RESULT
Self Diagnostic Result
Refer to DAS-108, "DTC Index".
FFD (Freeze Frame Data)
The accelerator pedal actuator records the fo llowing data when the malfunction is detected.
NOTE:
The number is 0 when is detected now.
The number increases like 1 → 2 ··· 38 → 39 after returning to the normal condition whenever IGN OFF →
ON.
The number is fixed to 39 until the self-di agnosis results are erased if it is over 39.
