Snapshot Data Table

NOTE:

The SAS control module stores the following two types of information when a DTC is detected and displays snap shot data in the M-MDS.
- Vehicle information detected by SAS control module
- Vehicle information detected by instrument cluster and received by SAS control module via CAN signal

The data for all DTCs currently detected is stored.

FAULT_CNT

Number of malfunction detections

FIRST_DET_IG

ss ⁽¹⁾

Time when initial malfunction occurs (IG-ON counter)

Elapsed time from when ignition is switched ON (engine off or on) until SAS control module detects first malfunction ⁽³⁾

IC_VPWR

Instrument cluster power supply voltage

The SAS 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 SAS control module records the power supply voltage of the instrument cluster when the DTC was detected, and it is displayed in the Mazda Modular Diagnostic System (M-MDS).

VPWR ⁽²⁾

IG-ON_TIMER

ss ⁽¹⁾

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 SAS control module 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 SAS 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 Mazda Modular Diagnostic System (M-MDS).

LAST_CLR

ss ⁽¹⁾

Repair time for last malfunction (B+ counter)

Elapsed time from when battery is connected until SAS control module detects that last malfunction is repaired ⁽³⁾

LAST_CLR_IG

ss ⁽¹⁾

Repair time for last malfunction (IG-ON counter)

Elapsed time from when ignition is switched ON (engine off or on) until SAS control module detects that last malfunction is repaired ⁽³⁾

LAST_DET

ss ⁽¹⁾

Time when last malfunction occurs (B+ counter)

Elapsed time from when battery is connected until SAS control module detects last malfunction ⁽³⁾

LAST_DET_IG

ss ⁽¹⁾

Time when last malfunction occurs (IG-ON counter)

Elapsed time from when ignition is switched ON (engine off or on) until SAS control module detects last malfunction ⁽³⁾

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 SAS control module constantly receives the ignition switch status sent via CAN signal from the instrument cluster.
If a DTC is detected, the SAS control module records the ignition switch status when the DTC was detected, and it is displayed in the Mazda Modular Diagnostic System (M-MDS).

RPM_STATUS

Engine Stop/Under1500rpm/Over1500rpm/
FAIL

Engine speed status

The SAS control module constantly receives the engine speed sent via CAN signal from the instrument cluster.
If a DTC is detected, the SAS control module records the engine speed when the DTC was detected, and it is displayed in the Mazda Modular Diagnostic System (M-MDS).

TACHOMTR ⁽²⁾

SHIFT_STATUS

P/N/D/R/
FAIL

Selector lever position status

The SAS control module constantly receives the selector lever position sent via CAN signal from the instrument cluster.
If a DTC is detected, the SAS control module records the selector lever position when the DTC was detected, and it is displayed in the Mazda Modular Diagnostic System (M-MDS).

TOTAL_DIST

Accumulated total traveled distance from completion of vehicle until SAS control module detects DTC (Odometer value in instrument cluster)

The total traveled distance from which the SAS control module 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

ss ⁽¹⁾

Accumulated total elapsed time since vehicle completion until SAS control module detects a DTC ⁽³⁾

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 SAS control module 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 ⁽²⁾

VPWR

SAS control module power supply

VPWR_IGA

VSPD_STATUS

Stop/0-10km/h/Over10km/h/
FAIL

Vehicle speed status

The SAS control module constantly receives the vehicle speed sent via CAN signal from the instrument cluster.
If a DTC is detected, the SAS control module records the vehicle speed when the DTC was detected, and it is displayed in the Mazda Modular Diagnostic System (M-MDS).

SPEEDOMTR ⁽²⁾

⁽²⁾	Instrument cluster PID (See PID/DATA MONITOR TABLE [INSTRUMENT CLUSTER] ).

⁽³⁾	The snap shot data of the number of stored malfunction detections, B+ counters, or IG ON counters is combined with the DTC detection conditions of the SAS control module, and the point-in-time data in the following table is stored.
