Replacement
Disconnect the 3-P connector trom the vehicle speed
sensor {VSS).
Remove ihe two mounting bolts, then remove the
VSS.
InstSll in the revsrse order of removal.
NOTE: The VSS drive link is a very small paru
caretul not to lose it.

1. Remove the YEL/RED wile from the engine oil pres-
sure switch.
ENGI'{E OIL PRESSURE SWITCH
Check tor continuitv between the positive torminal
and the engine {gtound) with the ignhion swhch OFF.
a lf there is continuity, go to step 3.
a lf there is no continuity, replace the switch.
Check for continuity again, this time with th€ engine
runnrng.
a lf there is continuity, go to step 4,
a lf there is no continuity, the switch is OK.
Make sure engine oil level is OK, then check engin€
oil pressure (s€e section 8).
a lf engine oil pressure is OK, replace the switch'
a lf engine oil pressure is low, check the sngine oil
pump (see section 8) and, if necessary, replac€ it.

Description
Based on signals recaived trom the vehicle speed sensor (VSS), the microcomputer in the maintenance remande, unit,which is located behind the dashboard lower cover, computes the distances traveled. When you turn the ignition switchon, the reminder light in the gauge assembly will come on for two seconds (bulb check tunction).Ar 9,650 t 160 km (6,000 t lOo miles) intervals, the reminder light witl gtow for two seconds and then btank ten sec-onds att€r you turn the ignition switch on. This will repeat every time you turn the ignition switch on until the car reaches12,O7O ! 160 km (7,500 1 10O mites).Beyond the 12,O7O ! 160 km (7,500 t IOO mite) interval, the tight will continue ro gtow after the butb check untilyou turn the ignition switch off or reset the unit.To reset the unit, the car must be pa.ked and the ignition switch must be on. Press the reset button on the unit for mo.ethan three seconds, and the reminder tight will go otf.
NOTE:
a Turn the ignition switch OFF b€fore you r€move the 5-P connector from the maintenance reminder unit. otherwiseyou will cancel all data in the memorv.a The data will remain in the memory even when the ignition switch is turned ofJ, or if the unit is disconnected. Whenthe ignition switch is turned on, and the car is driven. additional data will be stored.

Maintenance Reminder Unit Input Test
1.With the ignition switch OFF, disconnect the 5-P
connector from the reminder unit,
Inspect the connector and socket terminals to be
sufe they are all making good contact.
a lJ the terminals are bent, loose orcorroded, repair
them as necessary, and recheck the svstem.
a It the terminals look OK, make the following in-
Put tests at the connecto..- lf a test indicates a problem, tind and correct
the cause, then recheck the system.- It allthe input tests prove OK, the reminder unit
must be taulty; replace it.
