Theory Of Operation

The switch input changes when the switch is pushed down. A stored DTC B10C2 indicates that the Electronic Back Light (EBL) mode switch was stuck in a pushed position for more than 10 seconds, but has since returned to its normal state. An active DTC B10C2 indicates that the EBL mode switch is stuck in a pushed position. An active DTC B10C2 will prevent proper EBL mode switch and status indicator function.
