ON BOARD DIAGNOSTIC (OBD) SYSTEM HBC-81 < FUNCTION DIAGNOSIS > D E F G H I J K L M A B HBC N O P Relationship Between MIL and Detectable Items • When a malfunction is detected for the first time, DTC is stored in the hybrid vehicle control ECU memory. • When the same malfunction is detected in two consecutive trips, the DTC and the freeze frame data are stored in the hybrid vehicle control ECU memory for some DTCs. • The MIL will turn off after the vehicle is driven 3 times (driving pattern B) with no malfunction. The drive is counted only when the recorded driving pattern is met (as stored in the hybrid vehicle control ECU). If another malfunction occurs while counting, the counter will reset. • The DTC and the freeze frame data will be stored until the vehicle is driven 40 times (driving pattern A) with- out the same malfunction recurring. Summary Chart <Driving Pattern A> • The A counter will be cleared when the malfunction is detected regardless of (1) - (3). • The A counter will be counted up when (1) - (3) are satisfied without the same malfunction. • The DTC will not be displayed after the A counter reaches 40. <Driving Pattern B> Driving pattern B means the vehicle operation as per the following: All components and systems should be monitored at least once by the OBD system. • The B counter will be cleared when the malfunction is detected once regardless of the driving pattern. • The B counter will be counted up when driving pattern B is satisfied without any malfunctions. • The MIL will turn off when the B counter reaches 3. CONSULT-III Function INFOID:0000000004211756 FUNCTION *: The following emission-related diagnostic information is cleared when the hybrid vehicle control ECU memory is erased. SELF-DIAG RESULTS MODE Self Diagnostic Item Regarding items of DTC, refer to .) DATA MONITOR MODE Data Monitor NOTE: Items Operation Condition MIL Turns off 3 (pattern B) DTC, Freeze Frame Data No display 40 (pattern A) JMCIA0166GB Diagnostic test mode Function ECU Identification The hybrid vehicle control ECU part number can be read. Self Diagnostic result Self-diagnostic results such as DTC data can be read and erased quickly.* Data Monitor Input/Output data, freeze frame data and operation history data in the hybrid vehicle control ECU can be read. Active Test Diagnostic Test Mode in which CONSULT-III drives some actuators apart from the hybrid vehicle control ECU |
