WARRANTY CLAIM INFORMATION



The normal warranty applies.



Operation Number: 710103



Flat Rate Time: 0.2 hour



Failed Part: 32600-STX-A01



Defect Code: 06801



Symptom Code: 03205



Skill Level: Repair Technician



DIAGNOSIS



Check that the battery sensor fuse is the correct type and is not blown, and that the battery sensor 2P cable is connected:



^ On MDX, check for a blown No.9 (7.5 A) micro fuse in the main under-hood fuse box.



- If the No.9 fuse is blown, replace it with a 7.5 A micro fuse. Clear the DTC and the MID message, then recheck the system. If the fuse blows



again, troubleshoot its cause.



- If the No.9 fuse is OK, go to REPAIR PROCEDURE.



On ZDX, check for a blown No.11(7.5 A) mini fuse in the auxiliary under-hood fuse/relay box.



A 7.5 A micro fuse will fit in the No.11 slot, but won't provide the necessary electrical contact. This could lead to a misdiagnosis, because this poor



contact will eventually set the same DTC (B1192) and MID message (CHECK BATTERY SENSOR) as if the battery sensor has failed.



- If the No.11 fuse is blown, or is a micro fuse, replace it with a 7.5 A mini fuse. Clear the DIG and the MID message, then recheck the system. If



the fuse blows again, troubleshoot its cause.



- If the No.11 fuse is OK, and a 7.5 A mini fuse is in the slot, go to REPAIR PROCEDURE.



REPAIR PROCEDURE



1. Make sure the computer memory saver is fully charged and ready to use.



2. Write down the anti-theft code for the audio system or the audio/navigation system.



3. Connect the computer memory saver to the data link connector (DLC).



4. Make sure the ignition switch is in LOCK (0). On ZDX models with the keyless access system, make sure that the power mode is set to



VEHICLE OFF.



11



5. Disconnect the battery sensor 2P connector.



6. Disconnect the negative battery cable, and isolate it from the battery.



7. Remove the bolt securing the ground cable to the vehicle's body, then remove the negative battery cable assembly.



8. Attach the new negative battery cable assembly ground cable to the body. Torque its bolt to 6.9-11.8 Nm (5.0-8.7 lb-ft).



9. Attach the negative battery cable to the negative battery terminal. Torque its nut to 4.0-6.0 N.m (3.0-4.5 lb-ft).



10. Connect the battery sensor 2P connector.



11. Apply multipurpose grease to the battery terminals to prevent corrosion.



12. Disconnect the computer memory saver from the DLC.



13. Do the power tilt and telescopic steering wheel system memorization procedure:



^ On MDX, insert the retractable key into the ignition switch, then remove it. The steering wheel automatically moves fully in and up to let you



know the system has reset.



^ On ZDX, insert the retractable key into the ignition switch, then remove it. Or, on models with the keyless access system, set the power mode to



VEHICLE OFF. With either system, the steering wheel automatically moves fully up to let you know the system has reset.



14. Turn on the radio, and check the channel presets to make sure they are working.



15. If the tailgate was opened while the battery was disconnected, the power tailgate control unit must be reset. With both battery cables attached,



12



reset the control unit by manually lowering and fully closing the tailgate. Operate the power tailgate to make sure it has reset.



16. Initialize the navigation system (see page 3).



17. To clear the Battery Sensor DTC using the HDS, from the system selection menu:



^ Select BODY ELECTRICAL, then select GAUGES from the sub-system menu.



^ Next, select DTCs and clear the Battery Sensor DTC, using the CLEAR DTCs button.



18. To clear the AcuraLink message:



^ Press and hold MENU, MAP, and CANCEL simultaneously for about 5 seconds until the display changes to the DIAGNOSTIC ITEMS



mode.



NOTE:



DO NOT select DATA RESET on this screen; doing so will deactivate the client's AcuraLink account and all its settings.



^ Using the navigation system's interface dial, highlight DETAIL INFORMATION & SETTING, then select it by pressing Enter.



^ Select XM (HIP).



^ Select XM (HIP) DIAG.



^ Select DIAGNOSTIC INFO.



^ Select the Battery Sensor DTC; a message will appear; press Enter. At the "delete DTC" confirmation screen, press Enter, then Yes. The



DTC and AcuraLink display message will be erased.



INITIALIZING THE NAVIGATION SYSTEM



Any time the navigation system loses power, such as through battery disconnection, it must be initialized by doing these procedures, in this order:



^ Entering the Security Code



^ GPS Initialization



^ Map Matching



Entering the Security Code



Turn the ignition switch to ON (II). For ZDX models with the keyless access system, select the ON mode. Enter the client's 5-digit anti-theft security



code.



If the security code is lost or unavailable, you can get it from the iN using the navigation unit's serial number. To get the serial number without



removing the audio-navigation unit, do this:



^ Press and hold the MENU, MAP/GUIDE, and CANCEL buttons at the same time.



^ At the Select Diagnosis Items screen, select Detail Information & Settings > Unit Check > ECU Info.



The system runs a brief diagnosis, then the audio-navigation unit's serial number displays at the bottom of the screen.



^ Use the Anti-Theft Code Inquiry option on the iN to enter the navigation unit's serial number, which will then provide its 5-digit anti-theft code.



The iN may display more than one code for a given serial number. Because serial numbers are not unique, you may have to try entering more than



one 5-digit code. If no anti-theft code is shown, or if the codes given do not unlock the audio-navigation unit, call the Honda Automobile



Warranty Department.



GPS Initialization



Depending on the length of time the battery was disconnected, the system may require GPS initialization.



^ After battery reconnection, if the navigation system displays the disclaimer screen, GPS initialization is not needed. Go to Map Matching.



13



^ If GPS initialization is needed, this text box appears on the navigation screen:



To initialize the GPS system:



^ Park the vehicle outside with an unobstructed view of the sky, and leave the engine running. The system searches for available GPS satellites, and



gets their orbital signal information.



NOTE:



The average time to acquire a GPS signal is less than 10 minutes, but it can take as long as 45 minutes.



^ Once the navigation system acquires its GPS signal, it displays the disclaimer screen. Go to Map Matching.



^ If the system does not initialize within 10 minutes, this screen appears:



Follow the screen's instructions, moving the vehicle to a different location away from tall buildings, large trucks, trees, parking structures,



mountains, and/or tunnels.



Once the system initializes, the disclaimer screen appears. Go to Map Matching.



Map Matching



Drive the vehicle on a road shown on the navigation system's map screen. Do not enter a destination at this time.



When the name of the current road you are driving on appears at the bottom of the screen, the initialization process is complete.
