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 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

Locate the appropriate pinout adapter and load test loop adapter from EL-52552 COAX FAKRA Cable Adaptor Kit.
Connect the 2 adapters together, measure and record the resistance between the terminals at the pinout adapter.
Disconnect the 2 adapters and connect each one to the appropriate end of the coax cable.
At the pinout adapter test terminals, measure the total resistance of the coax cable loop including the connected load test adapter.
- If not within 5 Ω of the reading from step 10.
  Replace the coax cable
- Go to next step: If within 5 Ω of the reading from step 10.
All OK.
