If you set the multi- function switch to "AUTO" position, the tail lamp and head lamp will be turned automatically on or
off according to external illumination.

INSPECTION
While operating the auto light switch, check if the operations are normal as shown in the timing chart.
1. Auto light sensor value is always read at IGN ON.
2. Light is turned ON after 1sec±0.1sec when auto light sensor value is same as light ON input value.
3. Light is turned OFF after 2sec±0.2sec when sensor value is same as light OFF input value.
4. Tail lamp and head lamp are turned ON when sensor value is same as tail lamp ON input value.
5. Light ON value of sensor is based on the below table.
6. Head lamp signal is output when head lamp switch is ON. After head lamp is turned OFF, head lamp signal output
is immediately stopped if head lamp OFF luminance condition is met at auto light switch ON.
TAIL LAMP, AV LAMP HEAD LAMP
(low beam)
ON 1.77V+/ - 0.08V 0.63V+/ - 0.06V
OFF 3.47V+/ - 0.10V 1.02V+/ - 0.06V
T1 : 2 ± 0.2 sec
T2 : 2 ± 0.2 sec.
REPLACEMENT
Photo & auto light sensor inspection
1. Disconnect the crash pad (Refer to Body group - Crash pad).
2. Remove the Photo & auto light sensor (B) from crash pad.
3.Installation is the reverse of removal.

INSPECTION
1.The daytime running unit (A) is integrated in the IPM.
2.Functional diagram.
3.The DRL function operates the Head lamps High Beam at 50% of full illumination. The DRL function is active if :
a. the engine is running
b. the Head lamp multifunction switch is in OFF position or 'Park and Tail lamp' (Auto light function deactivated)
c. The Park break switch is OFF.
When the DRL function is active, the Head lamps High Beam can't be turned ON, except for the Flash To Pass
activation.
4. If the daytime running light is not operated well, Inspect the connector and terminals to be sure they are all making
good contact.
If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
If the terminals look OK, go to step 4.
5. Make these input tests at the connector by using ETM.
If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the IPM (In - panel module) must be faulty; replace it.
