Component Testing

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

Ignition OFF, disconnect the coax cable at both components.
Test for less than 5 Ω between coax cable center terminal end to end.
- If 5 Ω or greater
  Replace the coax cable
- If less than 5 Ω
Test for less than 5 Ω between the coax cable outer shield end to end.
- If 5 Ω or greater
  Replace the coax cable
- If less than 5 Ω
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
- If infinite resistance
All OK
