and install the battery.
1. Measuring continuity: Set the range to continuity test, short the red and black test leads, and the multimeter will
beeps, which indicating that the continuity is normal.
2. Measure the voltage: set the range to the DC voltage range (DC), connect the red and black test leads to the positive
and negative poles of the power supply for voltage measurement, and the AC voltage range (AC) measurement is the
same.
3. Measure the resistance: Turn the rotary swich to resistance ,and press “range”button to select the appropriate value.
Then
measure the resistance. Make sure that the circuit is powered off to avoid burning the multimeter.
4. Capacitance measurement: When the multimeter is hit to the capacitance, capacitance measurement can be
performed.
5. Measuring current: To measure the current, connect the red test lead to the A and mA holes. Select the range
according to the current of your circuit, and then connect the red and black test leads to the circuit for measurement.
6. Measuring diode: The range is set to the resistance level. Press the yellow button to select the diode level for diode
measurement. Pay attention to the positive and negative poles.
8.3. RTD temperature sensor measurement method:
1. Find the largest keyway of the motor resolver base and count the A.B.C.D.E.F pins from the direction of the flange
to the left
2.Using a multimeter ohm range, measure the resistance between A.B/C.D/E.F.
3.The cold state resistance is about 1.1K ohms. The hot state resistance is slightly larger than the cold state.
4.V pin is grounded, the resistance to ground should be OL, continuity state
8.4. IGBT measurement method:
1. Use a multimeter diode range. The negative test lead is on the positive of the DC high-voltage line. The positive
pole of the test lead is measured for each phase cable. The measured value is 0.34V-0.35V. After the measurement is
completed, the measurement is reversed. Test lead method (+ with black lead/ phase cable with red lead.-with red
lead / phase cable with black lead)
2. Use a multimeter resistance file, the negative pole of the test lead is opposite to the positive pole of the DC high-
voltage line, and the positive pole of the test lead is used to measure the cables of each phase. The measured value is
150 / 160k
Ω.
Measured as above. Test lead method (+ black / phase cable red.-red / phase cable black)
3. If the MCU reports 0x320D Error-Motor Control Machine 0x0D and 0x3100--3108Warning-Motor Control
Inverter 0x00--0x08 (different codes from different systems such as three-phase system points to 0x3102), it is
suspected that the IGBT has a problem and needs to replace a MCU.

．
The vehicle reports 0x320D Error-Motor Control Machine 0x0D when the vehicle is engaged. The vehicle cannot
run, we suspicion IGBT failure. Use the Graph function to collect data and send it to technical personel to analyze
for confirmation.
