FaultCrate・Replacement headlamp switch has no LED indicators and sets DTC B0951 (2003, normal)
The green and amber LED indicators are missing from the face of the switch.
Trouble code B0951 will be set in the BCM after a replacement switch is installed.
A running change was implemented starting with the 2004 model year, and the new replacement switch does not have the "auto" and "disable" LED indicators.
The BCM stores B0951 when a replacement switch is installed on a 2003 vehicle; this is due to the deletion of the LEDs and does not change the operation of the DRLs and headlamps.
