ODDTC Self Test

WARNING: This page is about a different car, the 2016 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.
  1. Connect the M-MDS to the DLC-2.
  2. After the vehicle is identified, select the following items from the initialization screen of the M-MDS.
    1. Select "Self Test".
    2. Select "Modules".
    3. Select "F_BCM".
  3. Verify the DTC according to the directions on the screen.
    • If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection.
  4. After completion of repairs, clear all DTCs stored in the front body control module (FBCM). (See CLEARING DTC [FRONT BODY CONTROL MODULE (FBCM)] .)

IC_VPWR V Instrument cluster power supply voltage
  • The front body control module (FBCM) 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 front body control module (FBCM) 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 front body control module (FBCM) 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 front body control module (FBCM) 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 front body control module (FBCM) constantly receives the ignition switch status sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the front body control module (FBCM) 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 front body control module (FBCM) constantly receives the engine speed sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the front body control module (FBCM) 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 front body control module (FBCM) constantly receives the selector lever position sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the front body control module (FBCM) 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 front body control module (FBCM) detects DTC (Odometer value in instrument cluster) The total traveled distance from which the front body control module (FBCM) detects DTCs to the present can be calculated by performing the following procedure.
  • Verify the odometer value in the instrument cluster.
  • Verify the snapshot data item TOTAL_DIST.
  • Subtract 2 from 1.
 -
TOTAL_TIME hh:mm:ss(2) Accumulated total elapsed time since vehicle completion until front body control module (FBCM) 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 front body control module (FBCM) detects DTCs to the present can be calculated by performing the following procedure.
  • Verify the instrument cluster PID item TOTAL_TIME.
  • Verify the snapshot data item TOTAL_TIME.
  • Subtract 2 from 1.
 TOTAL_TIME(1)
VPWR V Front body control module (FBCM) power supply voltage - VPWR_B
VSPD_STATUS Stop/0-10km/h/Over10km/h/FAIL Vehicle speed status
  • The front body control module (FBCM) constantly receives the vehicle speed sent via CAN signal from the instrument cluster.
  • If a DTC is detected, the front body control module (FBCM) 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.
