   INSPECT SPIRAL CABLE SUB-ASSEMBLY

   Note:
   

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

   • Remove the steering sensor from the spiral cable sub-assembly only when replacing the spiral cable sub-assembly.

   
   

   1. Visually check the spiral cable sub-assembly for defects.

      
      

      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 defects are found, replace the spiral cable sub-assembly with a new one.

      Check the spiral cable sub-assembly.

      Note:
      

      • When rotating the spiral cable sub-assembly, make sure to push on the interlock shown 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.

      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 O25-1 (CCS) - z5-3 (CCS) Always 3 Ω or less O25-2 (ECC) - z4-7 (ECC) Always 3 Ω or less O25-2 (ECC) - z5-4 (ECC) Always 3 Ω or less O25-3 (EAU) - z4-8 (EAU) Always 3 Ω or less O25-5 (AU2) - z4-10 (AU2) Always 3 Ω or less O25-6 (AU1) - z4-11 (AU1) Always 3 Ω or less O25-7 (SDN) - z4-12 (SDN) Always 3 Ω or less O25-8 (R/N) - z5-1 (R/N) Always 3 Ω or less O25-9 (HO) - z4-1 (HO) Always 3 Ω or less O25-10 (+DP) - z4-2 (+DP) Always 3 Ω or less O25-11 (+DP2) - z4-3 (+DP2) Always 3 Ω or less O25-12 (DIST) - z4-4 (DIST) Always 3 Ω or less O25-13 (IL+2) - z4-5 (IL+2) Always 3 Ω or less O25-14 (SUP) - z4-6 (SUP) Always 3 Ω or less O30-1 (D+) - z3-2 (D+) Always Below 1 Ω O30-2 (D-) - z3-1 (D-) Always Below 1 Ω O30-3 (D2-) - z2-1 (D2-) Always Below 1 Ω O30-4 (D2+) - z2-2 (D2+) Always Below 1 Ω O26-1 (BTM) - z8-1 (BTM)* Always 3 Ω or less O26-2 (EHT) - z8-3 (EHT)* Always Below 0.1 Ω O26-3 (ETM) - z8-2 (ETM)* Always 3 Ω or less O26-4 (BHT) - z8-4 (BHT)* Always Below 0.1 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.
