Question about 1989 Honda Prelude
Diagnostic light under foot rest blinking 17 times what its mean? And S4 indicator lamp below the temperature indicator blinking immediate after car is started, how to turn off the lamp?
I had the same problem, it should be the speed sensor on your transmisson after a while your speedometer will stop working. no clue on the lamp...

Tips for a great answer:
each time the ignition is cycled, all 5 mode indicators light simultaneously, as an indicator check to ensure proper operation of the indicators. when the ignition is on, the transfer case shift control module illuminates the indicator lamp that corresponds to the current atc gear position, by providing a ground through a current limiting driver.
the transfer case shift control module flashes each indicator lamp after a shift has been requested and continues to flash until the transfer case shift control module completes the shift.
a solid state circuit, located inside the switch, supplies ignition voltage to the lamps. the solid state circuit also receives voltage when the headlamp switch is in the parklamp or headlamp position. when the solid state circuit receives voltage from the headlamp switch, the circuit reduces the voltage that is supplied to the indicator lamps, dimming the lamps when the headlamps are on.
the numbers below refer to the step numbers on the diagnostic table.
ability of the transfer case shift control module to communicate through the data link connector (dlc)
existence of atc dtcs
