Headlamp Switch
After replacing the headlamp switch on a 2003 full size truck or utility you may notice the following changes.
1. The green and amber LED (light emitting diode) indicators are missing from the face of the switch.
2. Trouble code B0951 will be set in the BCM after a replacement switch is installed.
This is a normal condition. No repairs should be attempted.
A running change was implemented starting with the 2004 model year and the new replacement switch doesn't have the "auto" and "disable" LED indicators.
The BCM will store a trouble code B0951 when a replacement switch is installed on a 2003 vehicle. This is due to the deletion of the LEDs and will not change the operation of the DRLs and headlamps.
