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.
