SPIRAL CABLE INSPECTION


  1. INSPECT SPIRAL CABLE SUB-ASSEMBLY


    1. Remove the spiral cable with sensor sub-assembly from the vehicle Click here.

      Note

      Do not remove the steering sensor from the spiral cable sub-assembly.

    2. Visually check for defects on the spiral cable sub-assembly.


      1. The defects are as follows:


        • Scratches

        • Small cracks

        • Dents

        • Chips

        • Cracks or other damage to the connector

          OK
          No defects are found.

        If any of the defects is found, replace the spiral cable sub-assembly with a new one.

    3. Check the spiral cable sub-assembly.

      A01EUW4 Interlock - -

      Note


      • When rotating the spiral cable sub-assembly, make sure to push on the interlock indicated in the illustration to release the interlock mechanism.

      • As the spiral cable sub-assembly may break, do not rotate the spiral cable sub-assembly more than the specified amount.


      1. Set the spiral cable sub-assembly to the center position Click here.

      2. Measure the resistance between each terminal of the spiral cable sub-assembly according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        I28-1 (CCS) - z2-3 (CCS) Always 3 Ω or less
        I28-2 (ECC) - z2-4 (ECC) Always 3 Ω or less
        I28-3 (EAU) - z3-8 (EAU) Always 3 Ω or less
        I28-4 (AU3) - z3-9 (AU3) Always 3 Ω or less
        I28-5 (AU2) - z3-10 (AU2) Always 3 Ω or less
        I28-6 (AU1) - z3-11 (AU1) Always 3 Ω or less
        I28-9 (HO) - z3-1 (HO) Always 3 Ω or less
        I28-10 (+DP) - z3-2 (+DP) Always 3 Ω or less
        I28-11 (+DP2) - z3-3 (+DP2) Always 3 Ω or less
        I28-13 (IL+2) - z3-5 (IL+2) Always 3 Ω or less
        I27-1 (D+) - z4-2 (D+) Always Below 1 Ω
        I27-2 (D-) - z4-1 (D-) Always Below 1 Ω
      3. After setting the spiral cable sub-assembly to the center position, rotate the spiral cable sub-assembly 2.5 times clockwise, and measure the resistance according to the value(s) in the table below. Then rotate the spiral cable sub-assembly 5 times counterclockwise, and measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        I28-1 (CCS) - z2-3 (CCS) Always 3 Ω or less
        I28-2 (ECC) - z2-4 (ECC) Always 3 Ω or less
        I28-3 (EAU) - z3-8 (EAU) Always 3 Ω or less
        I28-4 (AU3) - z3-9 (AU3) Always 3 Ω or less
        I28-5 (AU2) - z3-10 (AU2) Always 3 Ω or less
        I28-6 (AU1) - z3-11 (AU1) Always 3 Ω or less
        I28-9 (HO) - z3-1 (HO) Always 3 Ω or less
        I28-10 (+DP) - z3-2 (+DP) Always 3 Ω or less
        I28-11 (+DP2) - z3-3 (+DP2) Always 3 Ω or less
        I28-13 (IL+2) - z3-5 (IL+2) Always 3 Ω or less
        I27-1 (D+) - z4-2 (D+) Always Below 1 Ω
        I27-2 (D-) - z4-1 (D-) Always Below 1 Ω
      4. After setting the spiral cable sub-assembly to the center position, rotate the spiral cable sub-assembly 2.5 times clockwise. Then while rotating the spiral cable sub-assembly 5 times counterclockwise, measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        I28-1 (CCS) - z2-3 (CCS) Always 3 Ω or less
        I28-2 (ECC) - z2-4 (ECC) Always 3 Ω or less
        I28-3 (EAU) - z3-8 (EAU) Always 3 Ω or less
        I28-4 (AU3) - z3-9 (AU3) Always 3 Ω or less
        I28-5 (AU2) - z3-10 (AU2) Always 3 Ω or less
        I28-6 (AU1) - z3-11 (AU1) Always 3 Ω or less
        I28-9 (HO) - z3-1 (HO) Always 3 Ω or less

        I28-11 (+DP2) - z3-3 (+DP2) Always 3 Ω or less
        I28-13 (IL+2) - z3-5 (IL+2) Always 3 Ω or less
        I27-1 (D+) - z4-2 (D+) Always Below 1 Ω
        I27-2 (D-) - z4-1 (D-) Always Below 1 Ω

        If the result is not as specified, replace the spiral cable sub-assembly.
