ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)]


id0402b2800200


On-Board Diagnostic (OBD) Test Description

•  The OBD test inspects the integrity and function of the DSC and outputs the results when requested by the specific tests.
•  On-board diagnostic test also:
―  Provides a quick inspection of the DSC usually performed at the start of each diagnostic procedure.
―  Provides verification after repairs to ensure that no other faults occurred during service.
•  The OBD test is divided into 3 tests:
―  Read/clear diagnostic results, PID monitor and record and active command modes.

Read/clear diagnostic results

•  This function allows you to read or clear DTCs in the DSC HU/CM memory.


PID/Data monitor and record

•  This function allows you to access certain data values, input signals, calculated values, and system status information.


Active command modes

•  This function allows you to control devices through the M-MDS.


Reading DTCs Procedure


CMDTC self test

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

(1)  Select “Self Test”.
(2)  Select “All CMDTCs”.

3.  Verify the DTC according to the directions on the screen.

•  If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection.

4.  After completion of repairs, clear all DTCs stored in the DSC. (See Clearing DTCs Procedure.)


ODDTC self test

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

(1)  Select “Self Test”.
(2)  Select “Modules”.
(3)  Select “ABS”.

3.  Verify the DTC according to the directions on the screen.

•  If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection.

4.  After completion of repairs, clear all DTCs stored in the DSC. (See Clearing DTCs Procedure.)


Clearing DTCs Procedure


CMDTC clearing DTCs procedure

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

(1)  Select “Self Test”.
(2)  Select “All CMDTCs”.

3.  Verify the DTC according to the directions on the screen.

4.  Press the clear button on the DTC screen to clear the DTC.

5.  Switch the ignition to off.

6.  Switch the ignition ON (engine off) and wait for 5 s or more.

7.  Perform DTC inspection. (See Reading DTCs Procedure.)

8.  Verify that no DTCs are displayed.

5.  Switch the ignition to off.

6.  Switch the ignition ON (engine off) and wait for 5 s or more.

7.  Perform DTC inspection. (See Reading DTCs Procedure.)

8.  Verify that no DTCs are displayed.


PID/Data Monitor and Record Procedure

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

(1)  Select “DataLogger”.
(2)  Select “Modules”.
(3)  Select “ABS”.

3.  Select the applicable PID from the PID table.

4.  Verify the PID data according to the directions on the screen.

Note
•  The PID data screen function is used for monitoring the calculated value of input/output signals in the module.Therefore, if the monitored value of the output parts is not within the specification, it is necessary to inspect the monitored value of input parts corresponding to the applicable output part control. In addition, because the system does not display an output part malfunction as an abnormality in the monitored value, it is necessary to inspect the output parts individually.

Active Command Modes Procedure

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

(1)  Select “DataLogger”.
(2)  Select “Modules”.
(3)  Select “ABS”.

3.  Select the simulation items from the PID table.

4.  Perform the active command modes function, inspect the operations for each parts.

•  If the operation of output parts cannot be verified after the active command mode inspection is performed, this could indicate the possibility of an open or short circuit, sticking, or operation malfunction in the output parts.


Snapshot Data Access Procedure

1.  Connect the M-MDS to the DLC-2.

2.  After the vehicle is identified, select the following items from the initialization screen of the M-MDS.

(1)  Select “Self Test”.
(2)  Select “Modules”.
(3)  Select “ABS”.

3.  Then, select the “Retrieve CMDTCs” and perform procedures according to directions on the M-MDS screen.

4.  Retrieve the snapshot data according to the directions on the M-MDS screen.

Note
•  Snapshot data appears at the top of the help screen when the displayed DTC is selected.
•  The snapshot data stores the currently detected DTC data.
