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.
- The vehicle may be equipped with sectioned coax. Test each section and replace only the faulty section, not the entire length of coax.
Coax Cable Test
- Ignition OFF, disconnect the coax cable at both components.
- Test for less than 5 Ω between the coax cable center terminal end to end.
- If 5 Ω or greater
Replace the coax cable.
- If less than 5 Ω
- If 5 Ω or greater
- Test for greater 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
- If 5 Ω or greater
- 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
- If less than infinite resistance
- All OK.
