Theory Of Operation
The switch input changes when the switch is pushed down. A stored DTC B1016 indicates that the Electronic Back Light (EBL) mode switch was stuck in a pushed position for more than 10 minutes, but has since returned to its normal state. An active DTC B1016 indicates that the EBL mode switch is stuck in a pushed position. An active DTC B1016 will prevent proper EBL mode switch and status indicator function.
