Operational Check=NJHA0130The purpose of the operational check is to confirm that the system
operates properly.
CONDITIONS:NJHA0130S01Engine running and at usual operating temperature.
NHA374
PROCEDURE:NJHA0130S021. Check BlowerNJHA0130S02011. Turn fan switch to 1-speed.
Blower should operate on 1-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 motor (HA-45).
If OK, continue with next check.
NHA375
2. Check Discharge AirNJHA0130S02021. Turn mode control knob to each position.
RHA280I
2. Confirm that discharge air comes out according to the air dis-
tribution table at left.
Refer to “Discharge Air Flow”, HA-19.
If NG, go to trouble diagnosis procedure for mode door motor
(HA-41).
If OK, continue with next check.
