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.

Diagnostic trouble code clearance
Using diagnosis check wire:
(a) Connect the 2 service wires to terminals Tc and AB of DLC1
or DLC2.
(b) Turn the ignition switch to ACC or ON and wait approx. 6
seconds.
(c) Starting with the Tc terminal, apply body ground alternately
to terminal Tc and terminal AB twice each in cycles of 1.0
seconds. Confirm that body ground is absolute. Finally, keep
applying body ground to terminal Tc.
HINT: When alternately grounding terminals Tc and AB, re-
lease ground from one terminal and immediately apply it to
the other terminal within an interval of 0.2 second. If diagnos-
tic trouble codes do not clear, repeat the above procedure un-
til the codes are cleared.
(d) Several seconds after doing the clearing procedure, the SRS
warning light will blink in a 50 m sec. cycle to indicate the
codes have been cleared.
Using TOYOTA hand±held tester:
(a) Hook up the TOYOTA hand±held tester to the DLC1 or DLC2.
(b) Clear the diagnostic trouble codes by following the prompts
on the tester screen.
HINT: Please refer to the TOYOTA hand±held tester opera-
tor 's manual for further details.
