Electrical Noise Test
23-75
Diagnostics CD 07AAZ-SDBA100
Do this test to check for electrical noise being induced
into the audio system.
NOTE: Electrical noise may be caused by outside
sources that cannot be handled by the audio system.
Make sure you remove any cell phones and/or turn off
any aftermarket device before beginning this test.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 4 (digital zero) at a normal, or slightly higher than normal, volume level.
3. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
4. Play track No. 5 (near digital zero) at a normal, or slightly higher than normal, volume level.
5. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
6. Play track No. 6 (SNR) at a normal, or slightly higher than normal, volume level. 7. Operate any electrical device that may create
electrical noise in the audio system, including
starting the engine.
If no abnormal noise is heard, go to individual speaker test.
If the noise is present only during the SNR track, replace the navigation unit or audio unit.
If the noise is heard during the digital zero or near digital zero track, check for;
– Poor ground for the audio unit, amplifier, engine or battery cable
– Pinched or shorted speaker or amplifier wire
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit
– Other faulty components causing excessive electrical noise (ignition coils, alternator, door
lock actuators, etc.). Disconnect any suspect
components, and then replay the tracks that
were originally noisy. If the noise is gone,
check the component’s circuit and the
component.

5. Turn the ignition switch to LOCK (0), then turn toON (II) and observe the navigation picture.
Check for sources of electrical noise, such as
poor battery connection, alternator, defective
battery, aftermarket accessories or cell phone, and
poor pin fits at the navigation unit.
Replace the navigation unit (see page 23-155). NOTE:
Check the vehicle battery condition first.
Always make sure that the correct DVD color and version are installed.
Check any official Honda service website for more service information about the navigation system.
Always check the connectors for poor connections or loose terminals.
Before troubleshooting, make sure you have the navigation and audio system anti-theft codes.
1. Turn the ignition switch to ON (II).
Replace the navigation unit (see page 23-155).
Refer to troubleshooting for no picture is
displayed (see page 23-119).
