DTC INSPECTION [LASER SENSOR]

id0402c4985000

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 “All CMDTCs”.

3.  Verify the DTC according to the directions on the screen.

•  If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection. (See DTC TABLE [LASER SENSOR].)

Note
•  Snapshot data appears at the top of the help screen when the displayed DTC is selected.
•  Snapshot data stores the currently detected DTC data.

4.  After completion of repairs, clear all DTCs stored in the module. (See CLEARING DTC [LASER SENSOR].)


Snapshot Data Table

Note
•  The laser sensor stores the following two types of information when a DTC is detected and displays snapshot data in the M-MDS
―  Vehicle information detected by laser sensor
―  Vehicle information detected by instrument cluster and received via CAN communication
•  Refer to PID monitor table for confirm the laser sensor system operation status while the laser sensor does not store the DTC. (See PID/DATA MONITOR TABLE [LASER SENSOR].)
•  Snapshot data items are not displayed, according to detected DTC.

Instrument cluster power supply
•  The laser sensor 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 laser sensor records the power supply voltage of the instrument cluster when the DTC was detected, and it is displayed in the M-MDS.

Elapsed time since ignition was switched ON
Note
•  The instrument cluster records the elapsed time since the ignition was switched ON.
•  The laser sensor 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 laser sensor records the elapsed time since the ignition was switched ON when the DTC was detected, and it is displayed in the M-MDS.

•  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
•  Ignition On (Position 2): Ignition switched ON (engine off)
•  Running (Position 2): Ignition switched ON (engine on)
•  Running - Starting: Cranking condition
•  The laser sensor constantly receives the ignition switch status sent via CAN signal from the instrument cluster.
•  If a DTC is detected, the laser sensor records the ignition switch status when the DTC was detected, and it is displayed in the M-MDS.

TOTAL_DIST
km, ft, mi
Accumulated total traveled distance from completion of vehicle until laser sensor detects DTC (Odometer value in instrument cluster)
The distance traveled when the laser sensor 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 laser sensor 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 when the laser sensor 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.
