CANCELLING OUT DIAGNOSTIC CODE
1.
2. After repair of the trouble area, the diagnostic code
retained in memory by the ECU must be cancelled out by
removing the EFI fuse 15A for 30 seconds or more,
depending on ambient temperature (the lower the tem-
perature, the longer the fuse must be left out) with the
ignition switch off.
NOTE:
l Cancellation can also be done by removing the battery”
negative (-1 terminal, but in this case other memory
systems (clock etc.) will also be cancelled out.
l If the diagnostic code is not cancelled out, it will be
retained by the ECU and appear along with a new code
in event of future trouble.
l If it is necessary to work on engine components requir-
ing removal of the battery terminal, a check must first
be made to see if a diagnostic code has been recorded.
After cancellation, road test the vehicle to check that a
“normal” code is now read on the “CHECK ENGINE”
warning light.
If the same diagnostic code is still indicated, it means that
the trouble area has not been repaired thoroughly.
DIAGNOSIS INDICATION
(I) When 2 or more codes are indicated, the lowest number
(code) will appear first.
However, no other code will appear along with code No.
11.
(2) All detected diagnostic codes, except 51 and 53, will be
retained in memory by the ECU from the time of detection
until cancelled out.
(3) Once the malfunction is cleared, the “CHECK ENGINE”
warning light on the instrument panel will go out but the
diagnostic code(s) remain stored in ECU memory (except
for codes 51 and 53).

(a) Install the timing belt to the IN side and EX side.
(b) Loosen the idler pulley bolt, and torque the idler
pulley bolt.
Torque: 500 kg-cm (36 ft-lb, 49 N.m)

NOTE: Make sure that the timing belt tension at A is
equal to that at B.
If not, readjust with the idler pulley.
(c) Turn the crankshaft pulley two revolutions clockwise
from TDC to TDC.
(d) Check that the matchmark on the camshaft timing
pulley are aligned with those on the No.2 timing belt
cover.
11. CHECK TIMING BELT TENSION
(a) Turn both the intake and exhaust camshaft pulleys
inward at the same time to slacken the timing belt at
position A.
Turning torque : 200 kg-cm (14 ft-lb, 20 N*m)
(b) Measure the timing belt deflection as shown.
Belt deflection at 2 - 3 kg (4.4 - 6.6 lb, 20 - 29 N):
Cold Used belt 5 - 7 mm (0.20 - 0.28 in.)
New belt 4 - 6 mm (0.16 - 0.24 in.1
Hot (Reference) 3 - 5 mm (0.12 - 0.20 in.)
If the measurement is not within specification, adjust by
the idler pulley.
