Edge ST 2022, Ambient light in the cupholder


Recommended Posts

Congratulations on your new Edge ST and welcome to the Forum.

 

While you specifically mention the cup holders, just in case you notice your Edge's entire ambient lighting is off, this recent discussion of 2022 ST ambient lighting may be useful if you have not already viewed it.

 

If you find that only your Edge's cup holder ambient lighting is inoperative (and not just off because the "on' setting is not retained from previous vehicle use), it would be best to make an appointment to have your dealer address the issue, since your Edge ST is brand-new and under warranty. 

 

There is no singular fuse for the Ambient Lighting, since it is controlled by the Body Control Module (BCM), which contains a Field Effect Transistor (FET) that protects the ambient lighting circuit, per this description from the 2022 Edge Workshop Manual...

 

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 three 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 three 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.

 

When you take your Edge in, a dealership Service technician may use the following Workshop Manual diagnostic test to determine the root cause of the problem...

 

(PARTIAL) PINPOINT TEST I: ONE OR MORE OF THE AMBIENT LIGHTING LIGHT EMITTING DIODES (LEDS) ARE INOPERATIVE OR DO NOT CHANGE COLOR/INTENSITY


Refer to Wiring Diagrams for schematic and connector information.

 

Normal Operation and Fault Conditions

REFER to: Interior Lighting - System Operation and Component Description (417-02 Interior Lighting, Description and Operation).

 

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
BCM B1465:00 Ambient Lighting Bus 1: No Sub Type Information Sets when the BCM detects a fault in the LIN circuit to the door ambient lighting Light Emitting Diodes (LEDs).
BCM B1467:00 Ambient Lighting Bus 3: No Sub Type Information Sets when the BCM detects a fault in the LIN circuit to the footwell and center console ambient lighting Light Emitting Diodes (LEDs).

I got the cupholder with the ice blue ambient lights, but because of the LIN bus I have no way of powering the lights. Unfortunately, as I was checking the connectors on my BCM, I do not have any wiring for ambient lights. 😓

 

Pin 13 on connector C2280G (LIN bus for cup holder) doesn't look too difficult to add a wire onto. The more challenging connector looks like pin 4 on connector C2280F (VPWR).

@HazThank you for the requested documents. Do you have a pinout for C2280F, as well as a service pigtail part / information for pin 4.

@HazThank you for the connector information.

 

I was able to take connector C2280G apart and insert a wire into pin 13 (LIN bus). Pin 4 on connector C2280F (VPWR) looks to challenging to take apart, so I will look for +12v elsewhere.

 

I connected power and LIN bus to my cup holder to test. Unfortunately, I was unable to get the cupholder to light up. And of course my multimeter also decided to not work! 😂 I think the battery is dead.

 

I was able to get the ambient light menu in the settings screen. The BCM will be a little bit trickier because I haven't found a reliable source of information on the BCM AsBuilt Data. I need to do further research and investigation into the BCM.

 

I would like to double check my wiring / new pin. Is there a way to test the connection to the LIN bus? Perhaps measuring the voltage or resistance of circuit VDN15 to confirm a good connection back to the BCM?

SUCCESS! 😊 I finally got this cupholder to light up! I connected LIN to the BCM, and I got power temporarily from the 12v power point. It took me a while to test the BCM configuration. I still need to go back and remove some unnecessary changes, such as the lost communication with seat module.
 

 

So, my next steps are to:

1. Finalize and document AsBuilt data

2. Run LIN wire from BCM driver’s area to center console area.

3. Find a permanent power source, possibly a nearby illumination circuit.

4. Replace cupholder (easy).
