Drive cycle

•  The drive cycle is the period of time from when the engine is started to the next time the engine is started.
•  One drive cycle, as shown in the figure, indicates the period from the time engine is started to the next time the engine is started. If this period is repeated twice it then becomes two drive cycles.
am3uun00002080
•  To detect DTCs, a required number of drive cycles for pre-detection has been set. For the number of drive cycles required for detection, refer to the DTC table.


Pending code

•  The pending code is temporary malfunction code which differs from DTCs which are recorded when the TCM detects a transaxle malfunction.
•  DTCs are recorded in the TCM according to the number of drive cycles when the TCM detects a transaxle malfunction. At the same time, pending code is recorded in the TCM regardless of the number of drive cycles.
•  Pending code recorded in the TCM is erased from the TCM, from the next drive cycle, when the TCM determines that the transaxle is normal.


Status byte for DTC

•  The status byte is the two-digit code (two digits after hyphen (-)) after the DTC.
am5uun00000323
•  The status byte is a code which indicates the pending code, current/past malfunction status, or warning illumination status.
•  The status byte can be read by performing a CMDTC self test using the M-MDS.
•  For details on the status byte, refer to the explanation on the M-MDS when reading the DTC.


Self-test function

•  When the self-test is implemented, the TCM performs diagnosis of the transaxle control system. If a malfunction is detected with the results of the diagnosis, an applicable DTC is recorded. A recorded DTC can be read by the M-MDS.
•  By implementing the self-test function, verification of the current malfunction and verification after repair is facilitated.
CMDTC (Continuous Memory Diagnostic Trouble Code) self-test
•  The CMDTC self-test is a function which reads all DTCs recorded in the TCM after the previous DTCs are erased no matter whether they are past malfunctions or current malfunctions.
KOEO (Key On Engine Off) self-test
•  The KOEO self-test can perform malfunction diagnosis of DTCs corresponding to this self-test function when the ignition is switched ON and the engine is stopped. This self-test implements based on the test implementation command signal sent to the TCM from the M-MDS.


Freeze frame data/Snapshot data

Freeze frame data
•  The freeze frame data consists of data for vehicle and transaxle control system operation conditions when malfunctions in the transaxle control system are detected and stored in the TCM.
•  Freeze frame data is stored at the instant the malfunction indicator lamp illuminates, and only a part of the DTC data is stored.
Snapshot data
•  The data for all DTCs currently detected is stored.
Recorded DTC timing
―  For DTCs with one drive cycle, data is recorded during the malfunction determination period.
―  For DTCs with two drive cycles, data is recorded during non-determination (1st diagnosis) periods.
