Snapshot Data

NOTE:
  • The radar unit stores the following two types of snapshot data (vehicle information) when a DTC is detected and displays them in the M-MDS.
    • Vehicle information detected by radar unit
    • Vehicle information detected by instrument cluster and received by radar unit via CAN communication
Snapshot data item Unit Definition Data read/use method Corresponding PID data monitor item
AAT °C °F Ambient temperature - -
APP_STATUS Accelerator Pedal
Off/Under20%/Over20%/FAIL		 Accelerator pedal position status - -
CFG_STATUS Config Complete/Not Configured/Config Error Instrument cluster configuration status - -
ECT_STATUS Under 0 degrees C/0 - Under 80 degrees C/Over 80 degrees C/FAIL Engine coolant temperature status - -
IC_VPWR V Instrument cluster power supply voltage
  • The radar unit 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 radar unit records the power supply voltage of the instrument cluster when the DTC was detected, and it is displayed in the M-MDS.
 VPWR (1)
IG-ON_TIMER hh:mm:ss (2) Elapsed time since ignition was switched ON (engine off or on)
NOTE:
  • The instrument cluster records the elapsed time since the ignition was switched ON (engine off or on).
  • The radar unit constantly receives the elapsed time since the ignition was switched ON (engine off or on) sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the radar unit records the elapsed time since the ignition was switched ON (engine off or on) when the DTC was detected, and it is displayed in the M-MDS.

PWR_MODE_KEY Key Out/Key Recently Out/Key Approved (Position 0)/Post Accessory (Position 0)/Accessory (Position 1)/Post Ignition (Position 1)/Ignition On (Position 2)/Running (Position 2)/Running - Starting In Progress (Position 2)/Crank (Position 3)
  • Key Out: Ignition switched to off
  • Key Recently Out: Elapsed time within 3 s since ignition was switched to off
  • Key Approved (Position 0): Remote transmitter approved by vehicle
  • Post Accessory (Position 0): Elapsed time within 3 s since ignition is switched to ACC
  • Accessory (Position 1): Ignition is switched to ACC
  • Post Ignition (Position 1): 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 In Progress (Position 2): Cranking condition
  • Crank (Position 3): Engine started condition
  • The radar unit constantly receives the ignition switch status sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the radar unit records the ignition switch status when the DTC was detected, and it is displayed in the M-MDS.
 -
RPM_STATUS Engine Stop/Under1500rpm/Over1500rpm/FAIL Engine speed status
  • The radar unit constantly receives the engine speed sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the radar unit records the engine speed when the DTC was detected, and it is displayed in the M-MDS.
 TACHOMTR (1)
SHIFT_STATUS P/N/
D/
R/
FAIL		 Selector lever position status
  • The radar unit constantly receives the selector lever position sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the radar unit records the selector lever position when the DTC was detected, and it is displayed in the M-MDS.
 -
TOTAL_DIST km miles Accumulate d total traveled distance from completion of vehicle until radar unit detects DTC (Odometer value in instrument cluster) The total traveled distance from which the radar unit detects DTCs to the present 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 (2) Accumulate d total elapsed time since vehicle completion until radar unit 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 from which the radar unit detects DTCs to the present can be calculated by performing the following procedure.
  1. Verify the instrument cluster PID item TOTAL_TIME.
  2. Verify the snapshot data item TOTAL_TIME.
  3. Subtract 2 from 1.
 TOTAL_TIME (1)
VPWR V Radar unit power supply voltage - VPWR
VSPD_STATUS Stop/
0-10km/h/
Over10km/h/
FAIL		 Vehicle speed status
  • The radar unit constantly receives the vehicle speed sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the radar unit records the vehicle speed when the DTC was detected, and it is displayed in the M-MDS.

(1) Instrument cluster PID (See PID/DATA MONITOR TABLE [INSTRUMENT CLUSTER] .)
(2) The seconds may be indicated after the decimal point.
