   Standard Resistance

   Tester Connection	Condition	Specified Condition
   k1-6 (ECC) - k1-4 (SPT)	Press continuously pattern select switch (SPORT)	Below 1 Ω
   	Release pattern select switch (SPORT)	10 kΩ or higher

4. Apply battery voltage between the terminals of the switch, and check the illumination condition of the pattern select sport switch.

   HINT: 

   • If a positive (+) battery lead and a negative (-) battery lead are incorrectly connected, the pattern select sport switch indicator light will not illuminate.

     If the voltage is too low, the indicator light will not illuminate.

   OK

   Measurement Condition	Specified Condition
   Battery positive (+) → Terminal 5 (IL+2) Battery negative (-) → Terminal 8 (EAU)	Illuminates

   If the result is not as specified, replace the steering pad switch.
