ON-BOARD DIAGNOSTIC SYSTEM [PCM (SKYACTIV-G 2.5T)]

id0102s8078000


Outline

•  The PCM performs self-diagnosis to check for malfunctions in the engine control system.

Function

•  If a malfunction occurs in the engine control system, the driver is notified.
•  On-board diagnosis can be performed easily using an external tester.

To meet the OBD regulations
•  Diagnostic test modes adopted
Improved serviceability
•  DTCs adopted
•  KOEO/KOER self test function adopted
•  PID/DATA monitor function adopted
•  Active command modes function adopted


On-board diagnostic function

Malfunction detection function
•  Functions to detect malfunctions which have occurred in the engine control system.
•  If a malfunction occurs, the PCM records the malfunction as a DTC. A recorded DTC can be read by the Mazda Modular Diagnostic System (M-MDS).
Diagnostic data memory function
•  Records diagnostic data related to the engine control system in the PCM.
•  Diagnostic data which can be recorded in the PCM are as follows:
―  Number of DTCs
―  DTC
―  Pending code
―  Freeze frame data
―  On-board diagnostic system diagnosis condition
•  The diagnostic data recording/erasing conditions are determined by the number of drive cycles set for each item. (See Sending emission-related malfunction code (DTC) (mode 03).)
•  Another method for erasing diagnostic data is by using the memory clearing function of the external tester.
Malfunction display function
•  Illuminates the check engine light to notify the driver of a malfunction occurring in the engine control system.
•  For details on the check engine light, refer to "Check Engine Light" item. (See CHECK ENGINE LIGHT [PCM (SKYACTIV-G 2.5T)].)
•  If the PCM detects that the engine control system is continuously normal for three drive cycles, the illuminated check engine light turns off. However, the DTC is not cleared from the PCM at this time. If the PCM determines that the engine control system is continuously normal for 41 warm-up cycles*, the DTC is cleared.
*: A warm-up cycle is a drive cycle including the period until the engine is completely warmed up after a cold-engine starts. This cycle repeated 41 times is a 41 warm-up cycle.
Self test function
•  On-board diagnosis is performed using the flow pre-set in the PCM, and according to the test execute command sent to the PCM from the external tester.
•  If a malfunction is detected as a result of the on-board diagnosis, a DTC is recorded in the PCM.
KOEO (Key ON, Engine Off) Self Test
―  The KOEO self test is a powertrain control system self-diagnosis, performed when the ignition is switched ON (engine off). A KOEO self test begins when the connected Mazda Modular Diagnostic System (M-MDS) sends an execute command to the PCM.
―  As the KOEO self test is performed, the PCM performs the inspection for set DTCs and if a malfunction is detected, the DTC is displayed on the Mazda Modular Diagnostic System (M-MDS).
KOER (Key ON, Engine Running) Self Test
―  The KOER self test is a powertrain control system self-diagnosis, performed when the ignition is switched ON and the engine is idling. A KOER self test begins when the connected Mazda Modular Diagnostic System (M-MDS) sends an execute command to the PCM.
―  As the KOER self test is performed, the PCM performs the inspection for set DTCs and if a malfunction is detected the DTC is displayed on the Mazda Modular Diagnostic System (M-MDS).

Meaning of fuel system loop status
•  The following information is displayed on the tester
―  Feedback stops: ECT is lower than the determined feedback zone
―  Feedback operating: A/F sensor, HO2S being used for feedback is normal
―  Feedback stops: Open loop due to driving condition
―  Feedback stops: Open loop due to detected system fault
―  Feedback operating: Malfunction occurred in HO2S system


Sending freeze frame data (mode 02)

Freeze frame data
•  The freeze frame data consists of data for vehicle and engine control system operation conditions when malfunctions in the engine control system are detected and stored in the PCM.
•  Freeze frame data is stored at the instant the check engine light illuminates, and only a part of the DTC data is stored.
•  For the freeze frame data, if there are several malfunctions in the engine control system, the data for the malfunction which occurred initially is stored. Thereafter, if a misfire or fuel injection control malfunction occurs, data from the misfire or fuel injection control malfunction is written over the initially stored data. However, if the initially stored freeze frame data is a misfire or fuel injection control malfunction, it is not overwritten.
Snapshot data
•  The snapshot data stores the currently detected DTC data.
•  The recording timing for the freeze frame data/snapshot data differs depending on the number of DTC drive cycles.
―  For a DTC with a drive cycle number 1, only the malfunction determination data is recorded.
―  For a DTC with a drive cycle number 2, both the malfunction determination and undetermined data is recorded.

Status byte for DTC

•  The two digits (two digits after hyphen (-)) after the 7-digit DTC.
ac5wzn00004012
•  A code which indicates the pending code, current/past malfunction status, or warning illumination status.
•  Can be read by performing a CMDTC self-test using the Mazda Modular Diagnostic System (M-MDS).
•  For details on the status byte, refer to the explanation on the Mazda Modular Diagnostic System (M-MDS) when reading the DTC.


Sending emission-related malfunction code (DTC) (mode 03)

•  The DTCs are shown below.
Note
•  When each warning/indicator light turns on/flashes, a message may be displayed in the multi-information display or the center display.

Sending continuous monitoring system test results (pending code) (mode 07)

•  These appear when a problem is detected in a monitored system.

If the problem is found in the second drive cycle too, the PCM determines that the system has failed, and stores the pending codes, and the DTCs.
