A close look at factory HID headlight assembly shows the HID low/high beam with igniter AND a inboard halogen bulb that appears to have no function in the OE HID application. In the 16 sport anyway.
I assume the assembly was built for the majority of non HID options ordered/built?

 

You are quoting a post from 2017!

 

2015-2018 Edges with factory HID have H15 bulbs on the inboard that function as DRL lights only.

H15 is a dual filament bulb designed as DRL for the low wattage filament and High beams for the high wattage filament, the Edge (with factory HID) only utilize's the low voltage filament, DRL. There is no wiring connected to the high wattage filament.

Interesting that ours don’t light on any setting........

Two HID’s and two amber lights in DRL.

In a US Edge, to get the DRL to turn on, you have to have them enabled in the settings menu in the cluster, headlight switch should on auto, and transmission shift lever out of Park.

So is it okay to run H11 HID in the low beam spot if DRL is disabled through the cluster?

Disabling DRLs through the cluster only affects the inboard (high beam position) and should not have any influence on the outboard bulb position.  At least on our 2016 Sport with factory HID projectors, that’s how it works.

What is used as the DRL differs depending on what type of headlight (halogen or HID) you have. If you have halogen then it is the low beam, if you have HID it is the dedicated H15 bulb.

  BCM Network Input Messages

 

Broadcast Message	Originating Module	Message Purpose
Gear position	PCM	Indicates the GSM request to the BCM . When the GSM has selected any position other than park, the BCM activates the DRL .

DRL

For the halogen headlamp system, the DRL system utilizes the existing circuitry and components from the headlamp low beam system. The DRL system operates the low beam headlamps at a reduced intensity.

 

For the High Intensity Discharge (HID) headlamp system, DRL system utilizes a halogen bulb in the headlamp assembly.

 

The BCM monitors the ignition status, the headlamp switch and autolamp status.

 

There are two types of DRL . Conventional (where it is required) and configurable.

 

When equipped with conventional DRL , the DRL are active in any headlamp switch position except the HEADLAMPS position.

 

When equipped with configurable DRL , the DRL may be enabled through the IPC message center. When enabled, the DRL are active only in the AUTOLAMPS headlamp position. When autolamps request the headlamps on, the DRL are de-activated.

 

The DRL are activated when the following conditions are met:

• the ignition is in run
• the headlamps have not been turned on by the autolamp system or the headlamp switch
• the transmission is not in park

When a turn signal is active, the corresponding daytime running lamp will turn off. Once the turn signal is deactivated, the daytime running lamp returns to normal operation.

 

When the transmission is in not in PARK, the PCM sends a message over the HS-CAN1 to the BCM indicating the transmission is not in PARK.

 

The BCM also provides Field Effect Transistor (FET) protection of the exterior lamps switched voltage and DRL output circuits. When an excessive current draw is detected, the BCM disables the affected circuit driver.

 

 

Field Effect Transistor (FET) Protection

The BCM utilizes an Field Effect Transistor (FET) protective circuit strategy for many of its outputs, for example, lamp output circuits. Output loads (current level) are monitored for excessive current (typically short circuits) and are shut down (turns off the voltage or ground provided by the module) when a fault event is detected.

 

A Field Effect Transistor (FET) is a type of transistor that the control module software uses to control and monitor current flow on module outputs. The Field Effect Transistor (FET) protection strategy prevents module damage in the event of excessive current flow.

 

Output loads (current level) are monitored for excessive current draw (typically short circuits). When a fault event is detected the Field Effect Transistor (FET) turns off and a short circuit DTC sets. The module resets the Field Effect Transistor (FET) protection and allows the circuit to function when the fault is corrected or the ignition state is cycled off and then back on.

 

When the excessive circuit load occurs often enough, the module shuts down the output until a repair procedure is carried out. Each Field Effect Transistor (FET) protected circuit has 3 predefined levels of short circuit tolerance based on a module lifetime level of fault events based upon the durability of the Field Effect Transistor (FET). If the total tolerance level is determined to be 600 fault events, the 3 predefined levels would be 200, 400 and 600 fault events.

 

When each level is reached, the DTC associated with the short circuit sets along with DTC U1000:00. These Diagnostic Trouble Codes (DTCs) can be cleared using the module on-demand self-test, then the Clear DTC operation on the scan tool (if the on-demand test shows the fault corrected). The module never resets the fault event counter to zero and continues to advance the fault event counter as short circuit fault events occur.

 

If the number of short circuit fault events reach the third level, then Diagnostic Trouble Codes (DTCs) U1000:00 and U3000:49 set along with the associated short circuit DTC . DTC U3000:49 cannot be cleared and the module must be replaced after the repair.
