BLOWER MOTOR CONTROL SYSTEM
BLOWER MOTOR CONTROL SYSTEM
System DescriptionINFOID:0000000001547339
SYSTEM DESCRIPTION
Component Parts
Blower motor speed control system components are: Front air control
 In-vehicle sensor
 Ambient sensor
 Sunload sensor
 Intake sensor
System Operation
Automatic Mode
In the automatic mode, the blower motor speed is calculated by the front air control based on input from in-
vehicle sensor, sunload sensor, intake sensor and ambient sensor.
The blower motor is applied voltage ranges from approximately 3.0 volts (lowest speed) to 12 volts (highest
speed).
The control blower speed (in the range of 3.0 to 12V), front air control supplies a gate voltage to the power
transistor. Based on this voltage, front air control controls voltage supplied to the blower motor.
Starting Blower Motor Speed Control
Start up from COLD SOAK Condition (Automatic mode)
In a cold start up condition where the engine coolant temperature is below 56°C, the blower will not operate for
a short period of time (up to 150 seconds). The exact start delay time varies depending on the ambient and
engine coolant temperature.
In the most extreme case (very low ambient) the blower starting delay will be 150 seconds as described
above. After this delay, the blower will operate at low speed until the engine coolant temperature rises above
56°C, at which time the blower speed will increase to the objective speed.
Start up from usual or HOT SOAK Condition (Automatic mode)
The blower will begin operation momentarily after the A/C switch is pushed. The blower speed will gradually
rise to the objective speed over a time period of 3 seconds or less (actual time depends on the objective
blower speed).
Blower Speed Compensation
Sunload
When the in-vehicle temperature and the set temperature are very close, the blower will be operating at low
speed. The low speed will vary depending on the sunload. During conditions of low or no sunload, the blower

Component Function CheckINFOID:0000000001547374
SYMPTOM: Insufficient cooling
INSPECTION FLOW
1.CONFIRM SYMPTOM BY PERFORMING OPERATIONAL CHECK - TEMPERATURE DECREASE
1. Press the AUTO switch.
2. Turn temperature control dial counterclockwise until 18° C (60° F) is displayed.
3. Check for cold air at discharge air outlets.
Can the symptom be duplicated?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK FOR ANY SYMPTOMS
Perform a complete operational check for any symptoms. Refer to HAC-202, "
Operational Check".
Does another symptom exist?
YES >> Refer to HAC-298, "SymptomMatrixChart".
NO >> System OK.
3.CHECK FOR SERVICE BULLETINS
Check for any service bulletins.
>> GO TO 3.
4.PERFORM SELF-DIAGNOSIS
Perform self-diagnosis Refer to HAC-213, "
Front Air Control Self-Diagnosis".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Refer to HAC-218, "
Front Air Control Self-Diagnosis Code Chart".
5.CHECK DRIVE BELTS
Check compressor belt tension. Refer to EM-15, "
Checking" HR16DE EM-142, "Checking Drive Belts" or
HR18DE or EM-263, "
Inspection and Adjustment" K9K.
Is the inspection result normal?
OK >> GO TO 6.
NG >> Adjust or replace compressor belt. Refer to XX-XX, "*****"
.
6.CHECK AIR MIX DOOR OPERATION
Check and verify air mix door mechanism for smooth operation. Refer to HAC-225, "
Air Mix Door Motor Com-
ponent Function Check"
Does air mix door operate correctly?
YES >> GO TO 7.
NO >> Check air mix door motor circuit. Refer to HAC-226, "
Air Mix Door Motor Diagnosis Procedure".
7.CHECK COOLING FAN MOTOR OPERATION
Check and verify cooling fan motor for smooth operation.
Does cooling fan motor operate correctly?
YES >> GO TO 8.
NO >> Check cooling fan motor. Refer to CO-18, "
Component (Models with A/C)".
8.CHECK RECOVERY/RECYCLING EQUIPMENT BEFORE USAGE
Check recovery/recycling equipment before connecting to vehicle. Verify there is no pressure in the recovery/
recycling equipment by checking the gauges. If pressure exists, recover refrigerant from equipment lines.

TROUBLE DIAGNOSIS
Condition of Error DetectionINFOID:0000000001162758
“U1000” or “U1001” is indicated on SELF-DIAG RESULTS on CONSULT-III if CAN communication signal is
not transmitted or received between units for 2 seconds or more.
CAN COMMUNICATION SYSTEM ERROR
 CAN communication line open (CAN-H, CAN-L, or both)
 CAN communication line short (ground, between CAN communication lines, other harnesses)
 Error of CAN communication control circuit of the unit connected to CAN communication line
WHEN “U1000” OR “U1001” IS INDICATED EVEN THOUGH CAN COMMUNICATION SYSTEM IS
NORMAL
 Removal/installation of parts: Error may be detected when removing and installing CAN communication unit
and related parts while turning the ignition switch ON. (A DTC except for CAN communication may be
detected.)
 Fuse blown out (removed): CAN communication of the unit may cease.
 Voltage drop: Error may be detected if voltage drops due to discharged battery when turning the ignition
switch ON (Depending on the control unit which carries out CAN communication).
 Error may be detected if the power supply circuit of the control unit, which carries out CAN communication,
malfunctions (Depending on the control unit which carries out CAN communication).
 Error may be detected if reprogramming is not completed normally.
NOTE:
CAN communication system is normal if “U1000” or “U1001” is indicated on SELF-DIAG RESULTS of CON-
SULT-III under the above conditions. Erase the memory of the self-diagnosis of each unit.
Symptom When Error Occurs in CAN Communication SystemINFOID:0000000001162759
In CAN communication system, multiple units mutually transmit and receive signals. Each unit cannot transmit
and receive signals if any error occurs on CAN communication line. Under this condition, multiple control units
related to the root cause malfunction or go into fail-safe mode.
ERROR EXAMPLE
NOTE:
 Each vehicle differs in symptom of each unit under fail-safe mode and CAN communication line wiring.
 Refer to LAN-27, "
Abbreviation List" for the unit abbreviation.
Example: TCM branch line open circuit
