checking operation of A/T. Flush cooling system after repair of
A/T.
lIf A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer toCO-12,

Operational CheckEJS001FE
The purpose of the operational check is to confirm that the system operates properly.
CHECKING BLOWER
1. Turn fan switch to 1-speed. Blower should operate on low
speed.
2. Then turn fan switch to 2-speed, and continue checking blower
speed until all speeds are checked.
3. Leave blower on 4-speed.
If NG, go to trouble diagnosis procedure for blower motorMTC-13
.
If OK, continue with next check.
CHECKING DISCHARGE AIR
1. Set the mode control dial to each position.
2. Confirm that discharge air comes out according to the air distri-
bution table.Refer to Discharge Air FlowMTC-5
.
Intake door position is checked in the next step.
If NG, go to trouble diagnosis procedure for mode door motor.
If OK, continue with next check.
CHECKING RECIRCULATION
1. Press REC switch one time. Recirculation indicator should illu-
minate.
2. Listen for intake door position change (you should hear blower
sound change slightly).
If NG, go to trouble diagnosis procedure for intake doorMTC-10
.
If OK, continue with next check.Conditions :Engine running and at
normal operating temper-
