Component Testing

CAUTION:

Refer to Test Probe Caution .

NOTE:

Before testing the coax cable, check the cable exterior for being pinched, cut, damaged, or having loose connections at the components, which can cause reception issues.

To prevent false reading when testing the center coax terminals, use care not to ground the test probe on the outer housing/shield.

Coax Cable Test

  1. Ignition OFF, disconnect the coax cable at both components.
  2. Test for less than 5 Ω between coax cable center terminal end to end.
    • If 5 Ω or greater 

      Replace the coax cable

    • Go to next step: If less than 5 Ω 
  3. Test for less than 5 Ω between the coax cable outer shield end to end.
    • If 5 Ω or greater 

      Replace the coax cable

    • Go to next step: If less than 5 Ω 
  4. Test for infinite resistance between the coax cable center terminal and the coax cable outer shield.
    • If less than infinite resistance 

      Replace the coax cable

    • Go to next step: If infinite resistance 
  5. All OK
