   Component without harness connected (Steering Pad Switch Assembly)

   *2

   Distance Control Switch

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

   Standard Resistance

   Tester Connection	Switch Condition	Specified Condition
   z5-4 (DIST) - z5-6 (ECC)	Distance control switch ON	Below 2.5 Ω
   z5-4 (DIST) - z5-6 (ECC)	Distance control switch OFF	10 kΩ or higher

4. Reinstall the steering pad. Refer to INSTALLATION .

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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   z5-4 (DIST) - F40-11 (DIST)	The spiral cable position is center	Below 1 Ω
   	The spiral cable position is 2.5 rotations to the left
   	The spiral cable position is 2.5 rotations to the right
   z5-6 (ECC) - F40-2 (ECC)	The spiral cable position is center	Below 1 Ω
   	The spiral cable position is 2.5 rotations to the left
   	The spiral cable position is 2.5 rotations to the right

   HINT: 

   The spiral cable makes a maximum of approximately 5 rotations.

3. Install the spiral cable sub-assembly. Refer to INSTALLATION .
