Pinpoint Test D : The Start-Stop Switch Illumination Is Inoperative Or Always On: Notes
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Starting System for schematic and connector information.
Normal Operation and Fault Conditions
The BCM supplies pulse-width modulated voltage to the start/stop switch illumination.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1314:11 | White Lighting (Reflective Controls) Illumination Output: Circuit Short To Ground | This DTC sets in continuous memory and on-demand when the BCM detects an excessive current draw from the illumination output circuit. |
| B1314:15 | White Lighting (Reflective Controls) Illumination Output: Circuit Short To Battery or Open | This DTC sets in continuous memory and on-demand when the BCM detects a lower than expected current draw from the illumination output circuit. |
| B1537:11 | Engine Stop-Start Button Backlight: Circuit Short To Ground | This DTC sets in continuous memory and on-demand when the BCM detects an excessive current draw from the illumination output circuit. |
| B1537:15 | Engine Stop-Start Button Backlight: Circuit Short To Battery or Open | This DTC sets in continuous memory and on-demand when the BCM detects a lower than expected current draw from the illumination output circuit. |
