DTC INSPECTION [DYNAMIC STABILITY CONTROL (DSC)]

id0402b2985000


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. (See DTC TABLE [DYNAMIC STABILITY CONTROL (DSC)].)

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

4.  After completion of repairs, clear all DTCs stored in the module. (See CLEARING DTC [DYNAMIC STABILITY CONTROL (DSC)].)


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. (See DTC TABLE [DYNAMIC STABILITY CONTROL (DSC)].)

4.  After completion of repairs, clear all DTCs stored in the module. (See CLEARING DTC [DYNAMIC STABILITY CONTROL (DSC)].)


Snapshot Data Table

Note
•  The DSC HU/CM stores the following two types of information when a DTC is detected and displays snapshot data in the M-MDS
―  Vehicle information detected by DSC HU/CM
―  Vehicle information detected by instrument cluster and received via CAN communication
•  Refer to PID monitor table for confirm the DSC system operation status while the laser sensor does not store the DTC. (See PID/DATA MONITOR TABLE [DYNAMIC STABILITY CONTROL (DSC)].)
•  Snapshot data items are not displayed, according to detected DTC.

Instrument cluster power supply
•  The DSC HU/CM constantly receives the power supply voltage value of the instrument cluster sent via CAN signal from the instrument cluster.
•  If a DTC is detected, the DSC HU/CM records the power supply voltage of the instrument cluster when the DTC was detected, and it is displayed in the M-MDS.

TOTAL_DIST
km, ft, mi
Accumulated total traveled distance from completion of vehicle until DSC HU/CM detects DTC (Odometer value in instrument cluster)
The distance traveled when the DSC HU/CM detected a DTC can be calculated by performing the following procedure.
1.  Verify the odometer value in the instrument cluster.
2.  Verify the snapshot data item TOTAL_DIST.
3.  Subtract 2 from 1.

TOTAL_TIME
hh:mm:ss*1
Accumulated total elapsed time since vehicle completion until DSC HU/CM detects a DTC
Note
•  When the ROOM fuse is removed, and the ignition is switched off, the time is not included in the elapsed time.
The elapsed time when the DSC HU/CM detected a DTC can be calculated by performing the following procedure.
1.  Verify the PID item TOTAL_TIME of the instrument cluster.
2.  Verify the snapshot data item TOTAL_TIME.
3.  Subtract 2 from 1.
