TIRE PRESSURE WARNING SYSTEM, Diagnostic DTC:C2198/98

DTC Code DTC Name
C2198/98 Initialization Switch (for Test Mode DTC)

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, "SET" is selected on the multi-information display and the "ENTER" switch (steering pad switch assembly)*1 or "DISP" switch (steering pad switch assembly)*2 is pressed, the tire pressure warning light illuminates. When the "ENTER" switch (steering pad switch assembly)*1 or "DISP" switch (steering pad switch assembly)*2 is not pressed, the tire pressure warning light blinks at 0.125-second intervals.


DTC No. DTC Detection Condition Trouble Area
