Use an ohmmeter to measure the resistance between the terminals. Check that the measured
value is at the standard value.
Standard value:

Between terminals 3 and 4 (LO)
|
2.15
|
Between terminals 2 and 4 (ML)
|
0.74
|
Between terminals 1 and 4 (MH)
|
0.27

When battery voltage is applied between the terminals, check that the motor operates.
Also, check that there is no abnormal noise.
