Special Tools Required

1. GNA600 kit and an iN workstation with AcuraLink update software
2. 256MB PCMCIA Memory Card
3. AcuraLink Reprogramming Cable

Note. Whenever you install a new AcuraLink control unit, you must update the control unit with the latest software. The GNA600 is the only tool currently available to update the AcuraLink control unit. If you are updating a control unit in a new vehicle, make sure all the fuses are installed. Make sure the iN workstation has the latest HDS software installed. (The AcuraLink update software is contained in the HDS update CD.) The update may take up to 60 minutes. You cannot update an AcuraLink control unit with its current or previous software versions. If will only accept a new software version. Before you update the AcuraLink control unit, test the vehicle battery (see BATTERY TEST ), and only proceed if the results are good. Make sure the battery is connected to a battery booster (not a battery charger) while updating the control unit. If the battery is not in good condition, or it dies during the updating procedure, you may damage the AcuraLink control unit. If you encounter errors in the software, follow the onscreen instructions, or if necessary, reboot the iN workstation, and try again. There are five process involved in updating the AcuraLink control unit. Setting up the GNA600 Capturing the current program ID from the AcuraLink control unit Download the new software to the GNA600 Update the software in the vehicle AcuraLink control unit Confirm the AcuraLink self-diagnosis Do the update with the ignition switch turned to LOCK (0). To prevent damage to the AcuraLink control unit, do not operate anything electrical (brakes, head lights, etc.) during the update. Check any official Honda service website for more service information about updating the AcuraLink control unit. To update the AcuraLink control unit, you must connect the GNA600 to the AcuraLink connector (A), not the DLC. Before you update an AcuraLink control unit, read the procedure. The order of connecting and disconnecting connectors is critical, and some steps must be done within a specified period of time. If the steps are not followed exactly, you may have to repeat the procedure from the start, and in same cases, you may damage the GNA600 or the AcuraLink control unit.

1. Make sure the ignition switch is turned to LOCK (0).
2. Open the trunk lid and remove rear shelf under cover (see «TRIM REMOVAL/INSTALLATION - TRUNK AREA»(/acura/rl/ii-2004-2008/remont/exteriorinterior-trim/#interior-trim__trim-removalinstallation-trunk-area) ).
3. Launch the AcuraLink Update program and follow the on-screen instructions to complete the update. NOTE: If the software in the AcuraLink control unit is the latest, disconnect the update tool from the AcuraLink connector. If the update is part of a troubleshooting or a repair procedure, return to that procedure and continue troubleshooting or repairing the vehicle.

System Description

The AcuraLink uses the client's portable telephone or XM radio to transmit and receive information about the vehicle. It is controlled via serial data communication by using a remote display and control unit in the vehicle. For Honda specific XM data, the remote display and control unit is the navigation unit. In addition, the AcuraLink system has a Text-To-Speech engine, and will also have the capability to initiate voice or data calls with the HandsFreeLink control unit.

Self-diagnostic Function

Note. Only select "DATA RESET" from the "XM (HIP) ECU" screen when instructed. Selecting "DATA RESET" will clear the AcuraLink registration, and the AcuraLink service will reset to the factory default. If the vehicle was already registered for the AcuraLink service, it will have to be reactivated by calling Acura Client Services before all features will be available.

The AcuraLink, built into the XM receiver has a self-diagnostic function. To run the self-diagnostic function, do the following

Scheme 150

1. Turn the ignition switch ON (II).
2. Press the interface dial.
3. Press the MAP GUIDE, CANCEL, and MENU buttons at the same time, and the self-diagnosis will begin.
4. Using interface dial, select the "NAVI System" from the "Select Diagnosis Items" menu. Press the interface dial. The display indicates "NAVI System Link", and will perform a Navi connection check for each device. If a connection is faulty, the place where it is faulty will be indicated with "NG" (red color). If the "XM (HIP)" indicator is "NG" (red color), go to step 5.
5. Using the interface dial, select the "Return" from the "Navi System Link". Press the interface dial.
6. Using the interface dial, select the "XM (HIP)" from the "Select Diagnosis Items" menu. Press the interface dial.
7. Using the interface dial, select the "XM (HIP) System Link" from the "XM (HIP)" menu. Press the interface dial. The display indicates "XM (HIP) System Link", and will perform an AcuraLink connection check for each device. If a connection is faulty, the place where it is faulty will be indicated with "NG" (red color).
8. When a red color is indicated, check the continuity between the XM receiver unit and the device indicated in red.

Cancelling the Self-diagnostic Function

1. Use the interface dial, select the "Exit Diag". Press the interface dial to cancel the self-diagnostic function.

Note. Check the vehicle battery condition first. If you can only tune to channel 000, 001,174, and 247, make sure that the audio unit is set to the channel mode (see owner's manual). If it is set to the channel mode, call XM radio customer support and check the account activation status.

1. Call Acura Client Services and verify the unit status. Request ACS to send an activation signal to the vehicle. Park the vehicle outside, and let the vehicle idle for about an hour. Does the AcuraLink service application work? YES - The vehicle is OK at this time. NO - Go to step 2.
2. Check the No. 21 (10A) fuse and No. 32 (10A) fuse in the driver's under-dash fuse/relay box. Are the fuses OK? YES - Go to step 3. NO - Replace the fuse(s), and recheck.
3. Turn the ignition switch to ON (II).
4. Measure the voltage between the No. 2 terminal of AcuraLink control unit connector A (20P) and body ground. Is there battery voltage? YES - Go to step 5. NO - Repair open in the wire(s) between the AcuraLink control unit and the No. 32 (10A) fuse in the driver's under-dash fuse/relay box.
5. Measure the voltage between the No. 12 terminal of the AcuraLink control unit connector A (20P) and body ground. Is there battery voltage? YES - Go to step 6. NO - Repair open in the wire(s) between the AcuraLink control unit and the No. 21 (10A) fuse in the driver's under-dash fuse/relay box.
6. Turn the ignition switch to LOCK (0).
7. Measure the voltage between the No. 11 terminal of AcuraLink control unit connector A (20P) and body ground. Is there less than 1 V? YES - Check for loose wires or poor connections at AcuraLink control unit connector A (20P). If the connections are good, substitute a known-good AcuraLink control unit, then the navigation unit and recheck until the problem goes away. Replace the original faulty component. NO - Check for an open in the wire between the AcuraLink control unit and body ground. If the wire is OK, check for poor ground at G602.
