FUSO 4M4 – HYBRID ELECTRIC VEHICLE SYSTEM – INSPECTION OF ELECTRICAL EQUIPMENT

#042 Inspection of stop lamp switch

• If any fault is found, replace the switch.

#302 Inspection of brake fluid pressure sensor
• Apply voltage 5 volts DC between terminals 1 and 3.
• Measure the output voltage generated between terminals 2 and 3.

• If the measurement is not within the range of the standard value, replace the sensor.

#437 Inspection of motor generator
• Remove the high voltage cable. (See “HIGH VOLTAGE CABLE, HIGH VOLTAGE BATTERY BOX AND MOTOR ELECTRONIC CONTROL UNIT”.)
<Revolution sensor and alternating current power supply>
• Measure values of resistance between the following terminals.

<Temperature sensor>
• Measure value of resistance between terminals 5 and 6.

• If the measured value deviates from the standard value, replace the clutch housing & motor generator. (See Gr22.)

#495 Inspection of blower motor
• Make sure that the fan operates when 24 volts DC is applied between terminals 1 and 2.
• If any fault is found, replace the motor.

#768 Inspection of water pump
• Perform the following checks, and if any fault is found, replace the water pump.
<Detailed inspection>
• Connect the hose to the OUT port. Put the IN side in a waterfilled container and the OUT side in an empty container.
• Apply voltage 24 volts DC between terminals 1 and 2.
• Measure the quantity of water discharged from the OUT side.

<Simple inspection>
• Put the IN side in a water-filled container.
• Apply voltage 24 volts DC between terminals 1 and 2 and check that the operating sound is heard.

#828 Inspection of controller area network resistor
• Measure the resistance between terminals 1 and 2.

• If the measured value is out of the standard value, replace the resistor.
