Component Testing

WARNING: This page is about a different car, the 2022 Cadillac CT4. 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's exterior for being pinched, cut, damaged, or having loose connections at the components, all of which can cause reception issues.
To prevent an incorrect reading when testing the center coax terminal, use care not to ground the test probe on the outer housing/shield.

Coax Cable Test

Test for less than 5 ohms between the test points: Coax Cable Center & The other end of the circuit
- If 5 ohms or greater
  Test or replace the component: Coax Cable
- Go to next step: If less than 5 ohms
Test for greater than 5 ohms between the test points: Coax Cable Outer Shield & The other end of the circuit
- If 5 ohms or greater
  Test or replace the component: Coax Cable
- Go to next step: If less than 5 ohms
Test for infinite resistance between the test points: Coax Cable Outer Shield & Coax Cable Center
- If less than infinite resistance
  Test or replace the component: Coax Cable
- Go to next step: If infinite resistance
All OK.
