Parking Brake Switch Test
Remove the tloor console, and disconnect the con-
nector from the switch.
Check for continuity b€tween the positive terminal
and body ground in each lever position accordino to
the table.
Canada:
lf the parking brake switch is OK, but ths brake sys-
tem indicator does not function, pertorm the input
test for the daytime running lights control unit (see
page 23-156).

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.
