Motor Pack Functional Test

Once the motor pack has been separated from the hydraulic modulator, this test will help to determine if the motor pack is operating properly.

The scan tool will rotate the motors in one direction, then the other. Observe the following:

• If any motor does not turn in both directions, the motor pack is malfunctioning and must be replaced. Refer to MOTOR PACK  .
• If all 3 hydraulic motors rotate, try to rotate each gear on the hydraulic modulator. Refer to NO GEAR MOVEMENT  .
