(2) Start the engine and check to see that, after raising the
engine speed by racing the engine, vacuum remains fairly
constant.
NOTE
If there is no vacuum created, it is possible that the throttle
body port may be clogged and require cleaning.

(1) Disconnect the vacuum hose from the throttle body purge
hose nipple and connect a hand vacuum pump to the
nipple.
(2) Start the engine and check to see that, after raising the engine speed by racing the engine, vacuum raises pro-
portionately with the rise in engine speed.
NOTE
If there IS a problem with the change in vacuum, ‘it is
possible that the throttle body port may be clogged and
require cleaning.

(1) Remove the purge control valve.
(2) Connect a hand vacuum pump to the vacuum nipple of the
purge control valve.
(3) Apply a vacuum of 400 mmHg (15.7 in.Hg.) and check
airtightness.
(4) Blow in air lightly from the evaporative emission Canister
side nipple and check conditions as follows.
(5) Connect a hand vacuum pump to the positive pressure
nipple of the purge control valve.
(6) Apply a vacuum of 400

16. DISCONNECTION OF DRIVE SHAFT

insert a pry bar between the transaxle case and the drive
shaft, and then pry the drive shaft from the transaxle.
Caution
1.Do not pull on the drive shaft; doing so will damage
the inboard joint; be sure to use the pry bar.
2.Do not insert the pry bar so deep as to damage the
oil seal.
(1) Take out the drive shaft by lightly tapping the drive shaft T.J. case with a plastic hammer.
NOTE
Remove the drive shaft with the hub and knuckle, etc.,
as an assembly.
Caution
1. Removing the drive shaft from the outboard
joint side can cause damage to the inboard joint.
Always use a plastic hammer, etc., to remove
the drive shaft.
2. Tapping on the center bearing can damage it. Never tap on the bearing.
(2) Keep the removed drive shaft as far away from the transaxle case as possible, and secure (by using rope.
etc.) the joints to the body so that it does not fall.

(2) Read
the
output fault

follow the remedy
procedures according to the
“Fault
Code Description”
on the following
page.
NOTE
l As many
as a maximum
of ten fault
codes, in the
sequence
of
occurrence,

can be stored
in the
Random Access

Memory (RAM) incorporated
within the
control
module.
l
The same

code can be stored
as many

If the number
of stored
fault
codes or

patterns
exceeds
ten,
already
stored
fault
codes
will be erased,
in
sequence
beginning
with the
oldest.
lDo
not
disconnect the

will

be canceled when
