Snapshot Data Table

NOTE:
  • The DSC HU/Control Module 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/Control Module
    • 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 (DSC HU/CONTROL MODULE) .)
  • Snapshot data items are not displayed, according to detected DTC.

IC_VPWR V Instrument cluster power supply
  • The DSC HU/Control Module 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/Control Module records the power supply voltage of the instrument cluster when the DTC was detected, and it is displayed in the M-MDS.

NOTE:
  • The instrument cluster records the elapsed time since the ignition was switched ON.
  • The DSC HU/Control Module 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/Control Module records the elapsed time since the ignition was switched ON 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/Control Module detects DTC (Odometer value in instrument cluster) The distance traveled when the DSC HU/Control Module detected a DTC can be calculated by performing the following procedure.
  1. Verify the odometer value in the instrument cluster.
  2. Verify the snap shot data item

    TOTAL_DIST.

  3. Subtract 2 from 1.
 -
TOTAL_TIME hh:mm:ss (2) Accumulated total elapsed time since vehicle completion until DSC HU/Control Module 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/Control Module 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 snap shot data item TOTAL_TIME.
  3. Subtract 2 from 1.
