Component Testing

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.

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

Coax Cable Test

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
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
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.
