Power Steering Motor: Service and Repair
Motor Replacement - Power Steering Assist (EPS)
Removal Procedure
1. Disconnect the sensor wire harness (6) from the motor/module assembly (5).
2. Important: If replacing the motor/module assembly, you will need the sensor wire harness strap clip (7) for the new motor/module assembly
installation.
If replacing the steering column, a new sensor wire harness strap clip (7) will come with the column service kit. Keep the existing wire strap clip
attached to the steering column sensor wire harness (6).
Use needle nose pliers to remove the wire strap clip (7) from the motor/module assembly (5). If replacing the motor/module assembly, remove the
wire strap clip (7) from the sensor wire harness (6). If replacing the steering column, keep the wire harness strap clip (7) attached to the sensor
wire harness (6).
3. Use a M6x1 head bit to remove the 2 motor/module assembly TORX screws (2). Discard the screws.
4. Important: Once the motor/module assembly has been removed, inspect the steering column assist mechanism input shaft (3) for the rotor
isolator bumper (4). If present, remove and insert back into the rotor isolator (8) in the motor/module assembly (5).
The assist mechanism housing must be free of any type of debris. Remove any loose debris from the steering column assist mechanism housing,
but do NOT remove the remaining grease on the steering column assist mechanism input shaft (3). Grasp the motor/module assembly (5) by the
motor housing and remove it from the steering column (1) by pulling with an even tension.
Installation Procedure
1. Notice: Do NOT allow the wiring harness to be pinched between the motor/module assembly and the steering column during installation. A
pinched harness will cause diagnostic trouble codes to be set and may require replacement of the steering column.
Important: Before installing the motor/module assembly (2), verify the rotor isolator bumper (1) is installed into the rotor isolator (3) in the
motor/module assembly (2).
Fit the motor/module assembly rotor isolator over the steering column assist mechanism input shaft.
