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, the tire pressure warning light blinks at 0.125 second intervals when "Set Pressure" is selected on the multi-information display, and illuminates when the "OK" switch (steering pad switch assembly) is pressed.
