STEERING LINKAGE INSPECTION

PROCEDURE


  1. INSPECT TOTAL PRELOAD

    Note


    • Inspect the total preload in a no-load condition by removing the tie rod assemblies RH and LH, and steering rack boots.

    • Temporarily install the left and right steering rack end sub-assemblies to prevent steering rack overstroke.


    1. A01MSF9N01

      Install SST to the pinion shaft and turn it left and right 5 times or more.

      SST
      09616-00011

    2. Using SST and torque wrench, turn the pinion shaft continuously at a rate of 4 to 6 seconds per turn to inspect the total preload of the power steering link assembly.

      Standard Preload
      1.5 to 2.4 N*m (16 to 24 kgf*cm, 14 to 21 in.*lbf)

      Note

      Inspect the total preload around the steering rack center position.

      If the total preload is not within the specified range, replace the power steering link assembly with a new one.

  2. INSPECT POWER STEERING LINK ASSEMBLY


    1. Disconnect the C1 power steering motor connector.

    2. A01MTMQC03
      *1 Power Steering Link Assembly
      *a Area to set negative probe
      *b

      Component without harness connected

      (Power Steering Motor)

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (W) - 3 (U) Always 0.07 to 10 Ω
      2 (V) - 1 (W) Always 0.07 to 10 Ω
      3 (U) - 2 (V) Always 0.07 to 10 Ω
      1 (W) - Power steering link housing* Always 100 kΩ or higher
      2 (V) - Power steering link housing* Always 100 kΩ or higher
      3 (U) - Power steering link housing* Always 100 kΩ or higher

      *: Touch the negative probe to the power steering link assembly housing at the position shown in the illustration to perform the measurement.

    3. Disconnect the C3 torque sensor connector.

    4. A01MSNUC02
      *a

      Component without harness connected

      (Torque Sensor)

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (INCS) - 7 (TQG2) Always 90 to 170 Ω
      2 (INSN) - 7 (TQG2) Always 300 to 430 Ω
      4 (TRQV) - 8 (TQG1) Always 4 to 14 Ω
      5 (OUCS) - 7 (TQG2) Always 90 to 170 Ω
      6 (OUSN) - 7 (TQG2) Always 300 to 430 Ω

    5. Disconnect the C2 motor rotation angle sensor connector.

    6. A01MRRZC02
      *a

      Component without harness connected

      (Motor Rotation Angle Sensor)

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (RZSN) - 2 (RZG) Always 50 to 140 Ω
      3 (RZV) - 2 (RZG) Always 15 to 45 Ω
      4 (RZCS) - 2 (RZG) Always 50 to 140 Ω
