All 2003 Infiniti Vehicles and later - equipped with XM(R) or SIRIUS(TM) Satellite Radio Receiver and Service
IF YOU CONFIRM:
A satellite (SAT) radio related incident has occurred on an Infiniti vehicle factory equipped with SAT radio.
ACTIONS:
First, refer to Chart A for a list of Infiniti vehicles that are pre-wired for SAT radio.
Second, refer to the Service Information section in this bulletin.
^ The Audio unit, SAT receiver, and Satellite Service may be OK.
Third, refer to the Service Procedure section shown in this bulletin.
^ The Service Procedure section contains a Diagnostic Flowchart. It will provide Symptoms and Possible Causes to help you judge the SAT radio
condition.
IMPORTANT:
The purpose of ACTIONS (above) is to give you a quick idea of the work you will be performing. You MUST closely follow the entire Service
Procedure as it contains information that is essential to successfully completing this procedure.
SERVICE INFORMATION
212
Vehicles with the hardware to receive SAT Radio can be identified by a special antenna (see Figure 1).
In order for SAT radio to work the vehicle must have all of the following:
^ SAT antenna (see Figure 1) and "N-Buss" harness (hidden in the vehicle)
^ Either a XM(R) or SIRIUS(TM) SAT receiver (hidden in the vehicle)*
^ A current, active and registered subscription to the appropriate* SAT radio provider
*IMPORTANT NOTES ABOUT SAT:
^ The type of SAT receiver the vehicle has XM(R) or SIRIUS(TM) determines which service is available for subscription.
^ A subscription registers to the SAT receiver not to the vehicle's in-dash Audio (head) unit harness etc.
^ Each SAT receiver has an Electronic Serial Number (ESN) used to register the subscription.
^ For SAT radio the Audio (head) unit is only a controller/sound amplifier. SAT radio reception occurs in and by the SAT receiver.
^ The quality of SAT radio reception just like regular radio can still be affected by environmental factors like buildings tunnels geographic
location etc. (For more information on SAT reception see Nissan TechTalk issue Sept./Oct. 2002)
^ Depending on the year and model of the vehicle, the SAT receiver can be located either in the rear of the vehicle or under the dashboard.

Service Procedure
TUNING TO PREVIEW CHANNEL
1. Determine which Satellite Radio receiver is installed in the vehicle (XM(R) or SIRIUS(TM)) as follows:
a. Turn the audio unit "ON".
b. Select SAT function (varies from model to model consult the Owner's Manual).
c. Try to tune in the Preview Channel for the receiver.
215
^ The Preview Channel for XM(R) is Channel 001. When you turn to Channel 001, the audio display will show "XM CH - 001" for a
couple of seconds then it will show "XM Preview" (see Figure 2).
^ The Preview Channel for SIRIUS(TM) is Channel 184. When you turn to Channel 184 the audio display will show "SR CH - 184".
Special Note For SIRIUS(TM) Preview Channels:
A SIRIUS(TM) receiver will receive the Preview Channel 184 and the 15 select channels for 180 days from the moment the receiver is first
turned on. After 180 days the preview channels will not be available.
216
2. Return to the SAT RADIO DIAGNOSTIC FLOWCHART shown.

SAT RADIO "ERROR" CODES
CHECK ANTENNA
1. Check antenna lead for cuts or wear.
218
2. Check antenna leads for proper installation (see Figure 3).
3. Perform electrical check of antenna looking for shorts or opens:
See Figure 3 for a view of the GREEN (terrestrial) and YELLOW (satellite) connectors plugged into an installed satellite receiver.
a. Unplug both antenna leads (see Figure 4) from the receiver. Check the connector for signs of water entry and/or corrosion.
219
b. Check each lead one at a time (see Figure 5).
^ The connector should be clean and dry inside with no visible corrosion.
^ There should be continuity from the center conductor to the shield.
^ The resistance value between the center conductor and the shield should match a "known good" cable or a new cable.
^ Write down your findings on the repair order for future reference.
c. Return to the SAT RADIO DIAGNOSTIC FLOWCHART.
REPLACE THE SAT ANTENNA
NOTE:
Installation instructions for all vehicles are available at www.NNAnet.com
A. Remove the existing antenna as follows:
1) Disconnect the cable connector from the receiver.
DO NOT CUT THE ANTENNA CABLE!
2) Pull up the antenna's tail. Working from the tail to the front of the vehicle slide a nylon cord or equivalent (example: dental floss 6
lb. fishing line) between the antenna and the vehicle's roof (see Figure 6).
3) Cut through the adhesive pad between the antenna module and vehicle's roof using a side-to-side cutting motion (see Figure 6).
220
NOTE:
There are magnets under the base of the antenna. You may not be able to slide the cord all the way through to the front.
If needed Carefully apply heat with a heat gun to the antenna to soften the existing adhesive-backed tape. Keep the heat gun's nozzle at
least 12 inches away from the antenna.
CAUTION:
Too much heat will damage the vehicle's paint or surrounding parts (rear window molding, window finishers, etc.).
Only an experienced paint technician who is familiar with paint temperature limitations should use a heat gun.
Important Points
^ DO NOT overheat the antenna or roof. Heat the area just enough to soften the adhesive tape for easy removal.
^ The heat gun wattage should not exceed 1400 watts.
^ Do not hold the heat gun nozzle closer than 12 inches from the roof surface. Also do not hold the heat gun in one position. Keep the
nozzle moving from side to side to evenly heat the tape.
4) Slowly pull up on the antenna and remove it.
DO NOT CUT THE ANTENNA CABLE!
B. Use a 50/50 alcohol/water solution to clean the area of the roof where the antenna was located of any small pieces of the tape or
adhesive.
C. Prepare the new antenna for mounting using the adhesive tape included in the antenna kit. You will also need to use clear butyl gum and
black tape for installation.
D. Install the replacement antenna. Be sure to handle the antenna wires carefully. Do not bend kink or push on the wires. Doing so may
damage the wires.
E. Re-connect the cable connector to the receiver.
F. Turn the ignition key to OFF position wait for 10 seconds then turn the ignition key to ACC position. Wait for the receiver to restart. If
the original symptom still exists SAT RADIO DIAGNOSTIC FLOWCHART.
GETTING THE SAT RADIO ESN & CONTACTING THE PROVIDER
1. Determine which Satellite Radio receiver is installed in the vehicle (XM(R) or SIRIUS(TM)):
a. Turn the audio unit "ON".
b. Push the SAT button.
c. Tune in the Preview Channel for the receiver.
^ The Preview Channel for XM(R) is Channel 001. A XM(R) receiver will display "XM1 CH - 001" (see Figure 2) on the Audio unit
face.
^ The Preview Channel for SIRIUS(TM) is Channel 184. A SIRIUS(TM) receiver will display "SR1 CH - 184" on the Audio unit
face.
2. Now tune to Channel 0.
a. The Audio unit face will first display "RADIO ID".
b. Then the Audio unit face will display a letter-number (alpha-numeric) code. XM(R) has an eight character letter-number code while
SIRIUS(TM) has a twelve character letter-number code. This code is the receiver ESN (electronic serial number).
c. Write down the code in the space provided below.
- - - - - - - - - - - -
3. Call the applicable service provider.
^ The number for XM(R) is: 1 (800) 852-9696.
^ The number for SIRIUS(TM) is: 1 (888) 539-SIRI.
221
a. Identify yourself as a repair station working with a customer's receiver.
b. Ask them to verify if a current subscription is applied to this receiver.
c. Give them the ESN (RADIO ID) you wrote down in step 2c above.
d. While you have them on the phone return to the SAT RADIO DIAGNOSTIC FLOWCHART. The provider's answer to the subscription
question (3b) will determine the next step.
REPLACEMENT OF THE SAT RECEIVER
The location of the satellite receiver varies from vehicle to vehicle. Some vehicles have the receiver located in the rear. Other vehicles have the
receiver located under the dashboard. Figure 7 shows a rear-mounted receiver.
When replacing a receiver note that vehicle-specific instructions are provided at www.NNAnet.com.
Special Note - SIRIUS(TM) Receivers ONLY:
A remanufactured SIRIUS(TM) receiver may not receive the Preview Channel 184 and the 15 select channels. Reason: The remanufactured receiver
was in use for more than 180 days.
To receive the preview channels (or any other specific channels) the remanufactured receiver must be reactivated. Contact SIRIUS(TM) to do this.
