   • If not between 658 and 806 Ω 

     Replace the component: B55 Hood Ajar Switch

   • Go to next step: If between 658 and 806 Ω 
7. B55 Hood Ajar Switch = Closed
8. Test for 2080 to 2545 Ω between the test points: Signal circuit terminal B & Signal circuit terminal C
   • If not between 2080 and 2545 Ω 

     Replace the component: B55 Hood Ajar Switch

   • Go to next step: If between 2080 and 2545 Ω 
9. B55 Hood Ajar Switch = open
10. Test for 2738 to 3350 Ω between the test points: Signal circuit terminal A & Signal circuit terminal B
