Snapshot Data Table

WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Refer to PID monitor table for confirm the EPS system operation status while the EPS does not store the DTC. (See PID/DATA Monitor Table .)
  • Snapshot data items are not displayed, according to detected DTC.

IC_VPWR V Instrument cluster power supply
  • The EPS 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 EPS 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 EPS 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 EPS CM records the elapsed time since the ignition was switched ON when the DTC was detected, and it is displayed in the M-MDS.

LAS_CUR A Lane-keep assist system control output current - -
MT_CURRENT A Motor current - MT_CURRENT
OH_CR_C No/Yes Current overheat protection control (complete) - OH_CR_C
OH_CR_M No/Yes Current overheat protection control (middle) - OH_CR_M
OH_HIST_C No/Yes History of overheat protection control (complete) - OH_HIST_C
OH_HIST_M No/Yes History of overheat protection control (middle) - OH_HIST_M
OH_IG_CNT_C - The number of times the ignition is switched ON during the period from when overheat protection control (complete) is finished to the time the next overheat protection control (complete) is started
  • Displays a maximum number of 255 times in which the ignition is switched ON until the first overheat protection control (complete) is started.
  • During overheat protection control (complete), the number of times the ignition is switched ON is not counted, and 0 is displayed.
 - OH_IG_CNT_C
OH_IG_CNT_M - The number of times the ignition is switched ON during the period from when overheat protection control (middle) is finished to the time the next overheat protection control (middle) is started
  • Displays a maximum number of 255 times in which the ignition is switched ON until the first overheat protection control (middle) is started.
  • During overheat protection control (middle), the number of times the ignition is switched ON is not counted, and 0 is displayed.
 - OH_IG_CNT_M
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 to 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
  • When a DTC is detected, the EPS CM receives the ignition switch condition being detected by the instrument cluster via CAN signals and displays it in the M-MDS.
 -
RPM_STATUS Engine Stop/Under 1500rpm/Over 1500rpm/
FAIL		 Engine RPM status
  • The EPS CM constantly receives the ignition switch status sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the EPS CM records the ignition switch status when the DTC was detected, and it is displayed in the M-MDS.
 TACHOMTR(2)
SHIFT_STATUS P/N D/R/
FAIL		 Shift position status
  • The EPS CM constantly receives the selector lever position sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the EPS CM records the selector lever position when the DTC was detected, and it is displayed in the M-MDS.

STR_ANG_EST ° Steering wheel estimated absolute angle - STR_AB_EST
STR_ANG ° Steering wheel angle - STR_ANG
STR_ROT_SPD °/s Steering wheel rotation speed - STR_ROT_SPD
STR_TRQ_S_M Nm Steering shaft torque (Main) - STR_TRQ_S_M
STR_TRQ_S_S Nm Steering shaft torque (Sub) - STR_TRQ_S_S
TOTAL_DIST km, ft, mi Accumulated total traveled distance from completion of vehicle until EPS CM detects DTC (Odometer value in instrument cluster) The distance traveled when the EPS CM 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(1) Accumulated total elapsed time since vehicle completion until EPS CM detects a DTC
NOTE:
  • When the ROOM removed, and the ignition is switched off, the time is not included in the elapsed time.
 The elapsed time when the EPS CM 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.
 TOTAL_TIME(2)
VPWR V Power supply - VPWR
VSPD KPH, MPH Vehicle speed - VSPD
VSPD_STATUS Stop/0 - 10km/h/Over 10km/h/
FAIL		 Vehicle speed status
  • The EPS CM constantly receives the vehicle speed sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the EPS CM records the vehicle speed when the DTC was detected, and it is displayed in the M-MDS.
