DTC INSPECTION [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)]

id09021n960300


CMDTC Self Test

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 after recording the snapshot data. (See DTC TABLE [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)

4.  After completion of repairs, clear all DTCs stored in the AFS control module. (See CLEARING DTC [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)


ODDTC Self Test

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 “AFS/ALM”.

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

•  If any DTCs are displayed, perform troubleshooting according to the corresponding DTC inspection after recording the snapshot data. (See DTC TABLE [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)

4.  After completion of repairs, clear all DTCs stored in the AFS control module. (See CLEARING DTC [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)


Snapshot Data

Note
•  The AFS control module stores the following two types of snapshot data (vehicle information) when a DTC is detected and displays them in the M-MDS.
―  Vehicle information detected by AFS control module
―  Vehicle information detected by instrument cluster and received by AFS control module via CAN communication
•  The data for all DTCs currently detected is stored.

IC_VPWR
V
Instrument cluster power supply voltage
•  The AFS 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 AFS 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 AFS 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 AFS 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 AFS control module constantly receives the ignition switch status sent via CAN signal from the instrument cluster.
•  If a DTC is detected, the AFS 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 AFS control module constantly receives the engine speed sent via CAN signal from the instrument cluster.
•  If a DTC is detected, the AFS 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 AFS control module constantly receives the selector lever position sent via CAN signal from the instrument cluster.
•  If a DTC is detected, the AFS 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 AFS control module detects DTC (Odometer value in instrument cluster)
The total traveled distance from which the AFS 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 AFS 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 AFS 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.
