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 .)
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.

VPWR ⁽²⁾

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 to 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.

RPM_STATUS

Engine Stop/Under 1500rpm/Over 1500rpm/FAIL

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.

TACHOMTR ⁽²⁾

SHIFT_STATUS

P/ND/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.

STR_ANG_C

Steering wheel angle (Calculated Value)

SIR_ANG_C

TCS

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.

Stop/0 - 10 km/h/Over 10 km/h/FAIL

When a DTC is detected, the DSC HU/CM receives the vehicle speed being detected by the instrument cluster via CAN signals and displays it in the M-MDS.

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.
