Diagnostic Test

TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, erase all Satellite Radio DTCs.
3. Turn the ignition and radio on.
4. Put the satellite radio in seek up mode for two loops around the band cycle.
5. With the scan tool, read the DTCs.
  Does the scan tool display active: B156B-Satellite Radio Antenna Circuit?
  
  Yes
  - Go to step 2
  No
  - Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the SYSTEM WIRING DIAGRAMS as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension. Repair as necessary.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
TEST RADIO
NOTE: In order to perform this test, you must secure a Known Good Satellite Antenna.
1. With the scan tool, record the DTCs.
2. Erase the DTCs.
3. Turn the ignition off.
4. Disconnect the Satellite Radio Antenna connector at the Radio.
5. Install a Known Good Satellite Radio Antenna at the back of the Radio.
6. Turn the ignition and radio on.
7. Put the satellite radio in seek up mode for two loops around the band cycle.
8. With the scan tool, read the active DTCs.
  Does the scan tool display: B156B-Satellite Radio Antenna Circuit as Active?
  
  Yes
  - Replace the Satellite Radio in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go to step 3
ANTENNA CABLE
