HEATER AND MANUAL AIR CONDITIONER (See P.B-174,180.)
OPERATION

DWhen the ignition switch is turned “ON”, the
blower relay is energized. If the blower switch
is turned “ON” (LO, ML, MH, or HI position)
in this condition, the blower is activated through
the circuit via resistor at a speed corresponding
to the blower switch position.TROUBLESHOOTING HINTS

1. Blower motor is energized at one switch position
and not energized at another.
DCheck resistor.
DCheck blower switch.
2. Blower motor is energized only when switch
is positioned in HI.
DCheck resistor.

DIAGNOSIS FUNCTION
ENGINE WARNING LAMP (CHECK ENGINE LAMP)
If an abnormality occurs in any of the following items related
to the MPI system, the engine warning lamp will illuminate
or flash. If the lamp remains illuminated or if the lamp
illuminates while the engine is running, check the diagnosis
code output.
However, the warning lamp will illuminate as bulb check for
5 seconds whenever the ignition switch is turned to the ON
position.
