The Low Beams Are On Continuously
Diagnostic Overview
The Low Beams Are On Continuously
Refer to Headlamps/Autolamps for schematic and connector information.
Normal Operation and Fault Conditions
Refer to Exterior Lighting .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B10A6:09 | Main Light Switch: Component Failure | A continuous memory and on-demand DTC that sets when the SCCM detects invalid input from the headlamp switch. |
| B1D00:15 | Left Low Beam: Circuit Short To Battery or Open | A continuous memory and on-demand DTC that sets when the BCM detects a short to voltage from the LH low beam output circuit. |
| B1D01:15 | Right Low Beam: Circuit Short To Battery or Open | A continuous memory and on-demand DTC that sets when the BCM detects a short to voltage from the RH low beam output circuit. |
| U1000:00 | Solid State Driver Protection Actived-Driver Disabled: No Sub Type Information | This DTC sets when the BCM has temporarily shut down the output driver. The module has temporarily disabled an output because an excessive current draw exists (such as a short to ground). The BCM cannot enable the output until the cause of the short is corrected, the DTCs have been cleared and a successful self-test is run. |
| U3000:49 | Control Module: Internal Electronic Failure | This DTC sets when the BCM has permanently shut down the output driver. The module has permanently disabled an output because an excessive current draw fault (such as a short to ground) has exceeded the limits that the BCM can withstand. CORRECT the cause of the excessive current draw before installing a new BCM. |
Visual Inspection and Diagnostic Pre-checks
- Inspect the headlamp switch for damage.
