MAINTENANCE
GENERAL NOTES:
wThere are two separate maintenance schedules,
namely A and B, which apply to different driving
conditions. Find out how the vehicle is driven, select the
appropriate schedule and service the vehicle
accordingly.
wEvery service item in the periodic maintenance list must
be performed.
wNext to the columns of periods in the schedule,
reference pages have been added for easy access to
service data and procedures necessary for each
operation.
wThe service interval for scheduled maintenance is
determined by the odometer reading or time interval,
whichever comes first, shown in the schedule.
wMaintenance services after the last period should be
performed at the same interval as before unless
otherwise noted.
wSkipping even one item in the list can cause the engine
to run poorly and increase exhaust emissions.

DTC 42 No.1 Vehicle Speed Sensor Signal Circuit
CIRCUIT DESCRIPTION
The No.1 vehicle speed sensor outputs a 4±pulse signal for every revolution of the rotor shaft, which is
rotated by the transmission output shaft via the driven gear. After this signal is converted into a more pre-
cise rectangular waveform by the waveform shaping circuit inside the odometer and trip meter, it is then
transmitted to the engine control module. The ECM determines the vehicle speed based on the frequency
of these pulse signals.

(d) Load driving
Waveform between terminals SP1 and E1 when vehicle
speed is approx. 20 km/h (12mph).
HINT: As the vehicle speed increases, the number of sig±
nals from SP1 increases.
HINT: In test mode, diagnostic trouble code 42 is output when vehicle speed is 5 km/h (3 mph) or
below.
