DESCRIPTION
The switch circuit inside the combination meter assembly turns on and off according to the steering pad switch assembly operation.
During test mode, when the steering pad switch assembly is operated, "TPMS" is selected on the multi-information display and the "ENTER" switch (steering pad switch assembly) is pressed, the tire pressure warning light illuminates, and when the "ENTER" switch (steering pad switch assembly) is not pressed, the tire pressure warning light blinks at 0.125 second intervals.
