Audio System - Error code: Check Antenna is displayed

NOTE:

Check the vehicle 12 volt battery condition first .
Check SXM radio reception in an open area. Poor reception/interference can be caused by tall buildings, mountains, or high-voltage power lines.
Check the connectors for poor connections or loose terminals.

Problem verification
-1. Turn the vehicle to the ON mode.

-2. Turn on the audio system, and select the XM radio.

Is Check Antenna displayed on the center display?

YES

Intermittent failure, the system is OK at this time.

NO

The failure is duplicated, go to step 2.

Determine possible failure area (SAT/TER circuit, others)

-1. Turn the vehicle to the OFF (LOCK) mode.

-2. Open the driver's door, and wait more than 1 minute.

-3. Disconnect the following connector.

Roof antenna 2P connector

-4. Turn the vehicle to the ON mode.

-5. Measure the voltage between test points 1 and 2.

Is there about 4.0 V - 5.0 V?

YES

Go to step 3.

Go to step 4.

XM antenna check
-1. Turn the vehicle to the OFF (LOCK) mode.

-2. Open the driver's door, and wait more than 1 minute.

-3. Substitute a known-good roof antenna .

-4. Reconnect all the connectors, and recheck.

Does the symptom go away?

YES

Replace the original roof antenna.

NO

Replace the tuner unit .

Open wire check (SH(SAT/TER) line)

-1. Turn the vehicle to the OFF (LOCK) mode.

-2. Open the driver's door, and wait more than 1 minute.

-3. Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Roof antenna 2P connector: disconnected
Test point 1	Roof antenna 2P connector (male terminals) No. 2:
Test point 2	Body ground

Is there continuity?

YES: Without navigation

The SH(SAT/TER) wire is not open. Go to step 5.

YES: With navigation

The SH(SAT/TER) wire is not open. Go to step 8.

There is an open in the wire. Replace the affected antenna lead.

Shorted wire check (SAT/TER line)

-1. Disconnect the following connector.

Audio unit connector N (2P)

-2. Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Roof antenna 2P connector: disconnected
	Audio unit connector N (2P): disconnected
Test point 1	Audio unit connector N (2P) No. 1
Test point 2	Body ground

Is there continuity?

YES

There is a short to body ground in the wire. Replace the affected antenna lead.

The SAT/TER wire is not shorted to ground. Go to step 6.

Shorted wire check (SAT/TER line to SH(SAT/TER) line)

-1. Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Roof antenna 2P connector: disconnected
	Audio unit connector N (2P): disconnected
Test point 1	Audio unit connector N (2P) No. 1
Test point 2	Audio unit connector N (2P) No. 2

Is there continuity?

YES

There is a short in the wire. Replace the affected antenna lead.

The SAT/TER wire is not shorted to the SH(SAT/TER) wire. Go to step 7.

Open wire check (SAT/TER line)

-1. Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	Roof antenna 2P connector: disconnected
	Audio unit connector N (2P): disconnected
Test point 1	Audio unit connector N (2P) No. 1
