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 DSC HU/CM does not store the DTC. (See PID/DATA MONITOR TABLE .)
Snapshot data items are not displayed, according to detected DTC.

IC_VPWR

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.

IG-ON_TIMER

hh:mm:ss⁽¹⁾

Elapsed time since ignition was switched ON

NOTE:

The instrument cluster records the elapsed time since the ignition was switched ON.

The DSC HU/CM constantly receives the elapsed time since the ignition was switched ON sent via CAN signal from the instrument cluster.
If a DTC is detected, the DSC HU/CM records the elapsed time since the ignition was switched ON when the DTC was detected, and it is displayed in the M-MDS.

Key Out: Ignition switched off
Key Recently Out (Position 0): Elapsed time within 3 s since ignition was switched off
Accessory (Position 1): Ignition is switched to ACC
Post Ignition (Position 2): Elapsed time within 3 s since ignition was switched ON
Ignition On (Position 2): Ignition switched ON (engine off)
Running (Position 2): Ignition switched ON (engine on)
Running - Starting: Cranking condition

The DSC HU/CM constantly receives the ignition switch status sent via CAN signal from the instrument cluster.
If a DTC is detected, the DSC HU/CM records the ignition switch status when the DTC was detected, and it is displayed in the M-MDS.

Engine RPM status

The DSC HU/CM constantly receives the ignition switch status sent via CAN signal from the instrument cluster.
If a DTC is detected, the DSC HU/CM records the ignition switch status when the DTC was detected, and it is displayed in the M-MDS.

SHIFT_STATUS

P/N
D/
R/
FAIL

Shift position status

The DSC HU/CM constantly receives the selector lever position sent via CAN signal from the instrument cluster.
If a DTC is detected, the DSC HU/CM records the selector lever position when the DTC was detected, and it is displayed in the M-MDS.

Inactive/Active

Traction control system

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.

Verify the odometer value in the instrument cluster.
Verify the snap shot data item TOTAL_DIST.
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.

Verify the PID item TOTAL_TIME of the instrument cluster.
Verify the snap shot data item TOTAL_TIME.
Subtract 2 from 1.

Vehicle speed status

The DSC HU/CM constantly receives the vehicle speed sent via CAN signal from the instrument cluster.
If a DTC is detected, the DSC HU/CM records the vehicle speed when the DTC was detected, and it is displayed in the M-MDS.
