Based on signals received from the vehicle speed sensor (VSS). the microcomputer in the maintenance reminder unit,which is located behind the dashboard lower cover, computes the distances traveled. When you turn the ignition switchON (ll), the reminder light in the gauge assembly will come on for two seconds (bulb check tunction). At 9,650 1 160km {6,000 1 1O0 miles} intervals, the reminder light will glow for two seconds and then blink ten seconds after you
turn the ignition switch ON (ll). This will repeat every rime you turn the ignition switch ON {ll) until rhe car reaches12,O7O ! 1 60 km (7,500 t 100 miles).
Beyond the 12.o1O ! 160 km (7,5OO t IOO mile) interval, the light will continue to glow after the bulb check untilyou turn the ignition switch otf or reset the unit.
To reset the unit, the car must be parked and the ignition switch must be ON (ll). Press the reset button on the unitfor more than three seconds, and the reminder light will go off.
NOTE:
. Turn the ignition switch OFF before you remove the 5P connector from the maintenance reminder unit, otherwise vouwiil cancel all data in the memory.
a The data will remain in the memory even when the ignition switch is turned off, or if the unit is disconnected. Whenthe ignition switch is turned ON (lll, and the car is driven, additional data will be stored.

1.With the ignjtion switch OFF, disconnect the 5P con-
nector from the reminder unit.
Inspect the connector and socket terminals to be
sure they are all making good contact.
a lf the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
a lf the terminals look OK, make the following in-
put tests at the connector.- lf a test indicates a problem, find and correct
the cause, then recheck the system.
lf all the input tests prove OK, the remind€r unit
must be faulty; replace it.

nector from the switch.
Check for continuity between the terminals in eachposition according to the table.
2.
Move the lever back and forth at each position
without touching the push button, and check fof
continuity within the range of free play.
lf there is no continuity within the range of freeplay, adjust the installing position of the switch
as described on the next page.
