Snapshot data

NOTE:
  • The electric parking brake 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 electric parking brake control module
  • Vehicle information detected by instrument cluster and received by electric parking brake control module via CAN communication

IC_VPWR V Instrument cluster power supply voltage  
  • The electric parking brake control module constantly receives the power supply voltage value of the instrument cluster sent via CAN communication from the instrument cluster.
  • If a DTC is detected, the electric parking brake control module 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 electric parking brake control module constantly receives the elapsed time since the ignition was switched ON (engine off or on) sent via CAN communication from the instrument cluster.
  • If a DTC is detected, the electric parking brake control module 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 (Position 0)/Accessory (Position 1)/Post Ignition (Position 2)/Ignition On (Position 2)/Running (Position 2)/Running - Starting  
  • 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 (engine off or on)
  • Ignition On (Position 2): Ignition switched ON (engine off)
  • Running (Position 2): Ignition switched ON (engine on)
  • Running - Starting: Cranking condition
  
  • The electric parking brake control module constantly receives the ignition switch status sent via CAN communication from the instrument cluster.
  • If a DTC is detected, the electric parking brake control module 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 electric parking brake control module constantly receives the engine speed sent via CAN communication from the instrument cluster.
  • If a DTC is detected, the electric parking brake control module 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 electric parking brake control module constantly receives the selector lever position sent via CAN communication from the instrument cluster.
  • If a DTC is detected, the electric parking brake control module records the selector lever position when the DTC was detected, and it is displayed in the M-MDS.
 -
TOTAL_DIST km Miles Accumulated total traveled distance from completion of vehicle until electric parking brake control module detects DTC (Odometer value in instrument cluster) The total traveled distance from which the electric parking brake control module 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) Accumulated total elapsed time since vehicle completion until electric parking brake 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 from which the electric parking brake control module 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 Electric parking brake control module power supply voltage - VPWR
VSPD KPH MPH Vehicle speed - -
VSPD_STATUS Stop/0-10km/h/Over10km/h/FAIL Vehicle speed status  
  • The electric parking brake control module constantly receives the vehicle speed sent via CAN communication from the instrument cluster.
  • If a DTC is detected, the electric parking brake control module records the vehicle speed when the DTC was detected, and it is displayed in the M-MDS.
 SPEEDOMTR (1)
(1) Instrument cluster PID (See PID/DATA MONITOR TABLE [INSTRUMENT CLUSTER] .)

(2) The seconds may be indicated after the decimal point.
