COMPONENT DESCRIPTION
Brush-less Motor
The blower motor utilizes a brush-less motor with a rotating magnet.
Quietness is improved over previous motors where the brush was the point of contact and the coil rotated.
Blower Motor Circuit
Component Function Check
1.CHECK OPERATION
Diagnosis Procedure
1.CHECK WITH SELF-DIAGNOSIS FUNCTION OF CONSULT
NOTE: If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010.
2.CHECK WITH ACTIVE TEST OF CONSULT
NOTE: Perform the inspection of each output device after starting the engine because the compressor is operating.
3.CHECK FUSE
Check 15A fuses (Nos. 21 and 22).
4.CHECK POWER SUPPLY FOR BLOWER MOTOR
4 - Ground: Battery voltage
5.CHECK BLOWER MOTOR GROUND CIRCUIT
1 - Ground: Continuity should exist.
6.CHECK BLOWER MOTOR CIRCUIT CONTINUITY
3 - 32: Continuity should exist.
7.CHECK A/C AUTO AMP. OUTPUT SIGNAL
8.REPLACE FUSES
9.CHECK BLOWER MOTOR POWER SUPPLY CIRCUIT FOR SHORT
4 - Ground: Continuity should not exist.
10.CHECK POWER SUPPLY OF THE FRONT BLOWER MOTOR RELAY
2, 3 - Ground: Battery voltage
11.CHECK FRONT BLOWER MOTOR RELAY GROUND CIRCUIT
1 - Ground: Continuity should exist.
12.CHECK BLOWER MOTOR SUPPLY CIRCUIT FOR OPEN
Check continuity between blower motor harness connector M31 terminal 4 and front blower motor relay harness connector J-4 terminal 5.
5 - 4: Continuity should exist.

P1550 battery current sensor
Description
The power generation voltage variable control enables fuel consumption to be
decreased by reducing the
engine load which is caused by the power generation of the generator. The
battery current sensor is installed
to the battery cable at the negative terminal. The sensor measures ...
