iPod(R) - Charging With Nissan Interface System

Classification: EL08-037

Reference: NTB09-003

Date: January 9, 2009

iPod(R) Charging with Nissan Interface System for iPod(R)

APPLIED VEHICLES: All Nissan with Nissan Interface System for iPod(R)

(factory installed or accessory installed)

SERVICE INFORMATION

Please be aware that a recent design change was made by Apple to their iPod(R) and iPhone(R) products. As a result of this change, some customers

may report that their iPod(R)/iPhone(R) device does not charge while connected to the Nissan Interface System for iPod(R).

The Nissan Interface System for iPod(R) was designed to charge the customer's iPod(R) with a 12-volt power source, which has been supported by

all Apple iPod(R) and iPhone(R) devices until the latest generation. After Apple's design change, these new devices only support charging via a

5-volt source, which the Interface System does not provide. Customers may see error messages on the device screen, or notice that the device's

battery discharges while connected to their vehicle's interface system. Please note that while charging may not be supported playback and control

through the vehicle's audio system are still available.

Compatible Devices:

All Apple devices that support charging via a FireWire(R) connection are compatible with the Nissan Interface System for iPod(R). These include:

^ iPod(R) Classic - 1st through 6th generation

^ iPod(R) Mini - 1st through 2nd generation

^ iPod(R) Nano - 1st through 3rd generation

^ iPod(R) Touch - 1st generation

^ iPhone(R) - 1st generation

NOTE:

Refer to the vehicle Owner's Manual for further Nissan Interface System Information.

Non-compatible devices (as of 12/8/2008):

^ iPhone(R)3G

^ iPod(R) Nano - 4th generation

^ iPod(R) Touch - 2nd generation

Nissan is working closely with Apple to ensure full compatibility with our future Interface Systems, but as Apple's change was made without

adequate notification to Nissan, at this time there is no plan to modify the current Interface Systems for the 2009 model year.

Please make customers aware that there are products available in the aftermarket designed to reduce the 12V power source to 5V and should enable

their device to charge while connected to their vehicle. A few examples are provided below, however, Nissan expects these types of aftermarket

solutions to become even more widely available considering that Apple's change has impacted the charging ability of many automotive OEM's

iPod(R) integration systems.

Aftermarket Solutions:

PLEASE NOTE:

Nissan has not tested any of these aftermarket solutions and makes no endorsement, warranty, or guarantee of performance or compatibility for any

specific third party accessory. These devices are advertised by their respective manufacturers to resolve 12V to 5V charging issues, but have not

been designed for or tested with Nissan vehicles.

EXTERIOR LAMP FOGGING

This bulletin has been amended. The Applied Vehicles section and the first paragraph of the Service Information section have been revised. Please

discard all previous versions.

APPLIED VEHICLES: 2001-2012 Nissan, All Models

2017 Nissan-Datsun Altima L4-2.5L (QR25DE) Page 158

SERVICE INFORMATION

Occasionally customers may notice water vapor or fog in the exterior lamps. This is generally NOT due to a defect.

The following information, illustrations, and flow chart are provided to help you in determining if an incident for water/condensation in the lamps is

normal or not.

All current exterior lamp assemblies are vented to the atmosphere (not sealed).

^ This is necessary to allow for expansion and contraction of air from temperature "variations" (warmer or colder) without damage to the lamp.

^ Moisture in the air sometimes "travels" into and out of the lamp assembly through these vents.

^ Certain environmental conditions may cause moisture to condense.

^ The fogging/cloudiness should disappear over time when the lamp is in a dry environment.

Fog may temporarily form inside the lens of the exterior lamp assemblies based on environmental conditions or sudden temperature changes (such as

in a car wash, or parked on a cold, sunny day). This is normal. See Figure 1.

NOTE:

This condensation can appear anywhere on the outer lens, typically at its coldest location.

If the moisture trickles, drips, or pools, it may not be considered normal and the lamp assembly may have a water leak path. See Figure 2 for an

example.

If large drops of water collect inside the lens, refer to the flow chart below to find the next step.

SERVICE PROCEDURE

Should a customer note water in a lamp assembly, please use the following flow chart to determine if the condition is normal or requires lamp

REMOVAL PROCEDURE FOR SEIZED EXHAUST SENSOR

APPLIED VEHICLES: All Nissan vehicles

SERVICE INFORMATION

If an exhaust sensor is seized in the exhaust manifold/catalyst/front tube, perform the procedure described in this bulletin to remove the sensor and

prevent unnecessary replacement of the exhaust manifold/catalyst/front tube.

In most cases this procedure is successful. This is because the threads of the exhaust sensors are made of a softer material than the part they thread

into on the exhaust manifold/catalyst/front tube.

NOTE:

The replacement of exhaust manifolds/catalysts/front tubes for stripped exhaust sensor threads may not be considered a warrantable expense.

This procedure can be performed by two methods:

Method #1 - If the Sensor Can Be Easily Accessed

Service Procedure

Rust Penetrant

Recommended rust penetrants to be used in this procedure:

NOTES:

^ Rust penetrant is considered a shop supply.

^ Nissan Rust Penetrant can be ordered through the Nissan Direct Ship Chemical Care Product Program, Website order via link on dealer portal.

^ WD-40 is available from various local sources.

Removal Tool

^ When removing a seized exhaust sensor with a specialty socket (which contains a slit to accommodate the wiring harness), it may spread open and

strip the sensor.

^ Before this occurs, it is recommended to cut the wiring harness from the sensor and use a box end wrench or 6-point deep well socket.

1. Clamp the exhaust manifold/catalyst/front tube in a vice.

2. Spray the sensor with the rust penetrant for 2 to 3 seconds.

^ It is important that the spray is directed at the base of the sensor to ensure it penetrates into the threads.

3. Loosen the sensor approximately 10 degrees.

4. Spray with rust penetrant again for 2 to 3 seconds.

5. Tighten the sensor 10 degrees, then loosen the sensor 10 degrees.

^ Repeat this motion several times until the sensor begins to turn more easily.

6. Continue the tightening/loosening motion while gradually unscrewing the sensor. Stop when the sensor will not unscrew any further.

7. Spray with rust penetrant again for 2 to 3 seconds.

8. Repeat steps 6 and 7 until the sensor is removed.

9. Use compressed air to remove any metal debris from inside the boss threads.

CAUTION:

DO NOT perform this step if the procedure is being done on the vehicle (Method #1). Doing so may cause metal debris to enter the engine cylinders.

10. If metal debris remains trapped in the boss threads, use a spiral nylon brush to remove it.

11. Spray the boss threads with rust penetrant for 2 to 3 seconds.

12. Run a thread chaser through the boss to clean the threads.

^ Use Kent Moore part number J-43897-18 or J43897-12.

13. Use compressed air to remove any remaining debris.

CAUTION:

DO NOT perform this step if the procedure is being done on the vehicle (Method #1). Doing so may cause metal debris to enter the engine cylinders.

14. If metal debris remains trapped in the boss threads, use a spiral nylon brush to remove it.

15. Tilt the manifold/catalyst/front tube so that the metal debris falls out of the part.

16. Apply compressed air through the boss to blow out any remaining debris.

CAUTION:

DO NOT perform this step if the procedure is being done on the vehicle (Method #1). Doing so may cause metal debris to enter the engine cylinders.

17. Install the new sensor as described in the applicable Electronic Service Manual (ESM).
