   • If infinite resistance 
3. Test for 1.0k - 1.5k Ω between the control circuit terminal 2 and ground circuit terminal 7 while pressing forward collision alert switch.
   • If not between 1.0k - 1.5k Ω 

     Replace the S70L Steering Wheel Controls Switch - Left.

   • If between 1.0k - 1.5k Ω 
4. All OK.
