Scheme 618: How to Check for DTCs with the HDS
  1. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
  2. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
  3. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
  4. Make sure the HDS communicates with the vehicle and the AcuraLink control unit (XM receiver). If it does not, troubleshoot the DLC circuit (see «DLC CIRCUIT TROUBLESHOOTING»(/acura/zdx/i-2009-2013/remont/communication-devices/#communication-systems-f-can-k-line__dlc-circuit-troubleshooting) ).
  5. Select XM/HIP in the BODY ELECTRICAL menu.
  6. Select DTCs in the XM/HIP menu.
  7. Check for DTCs. If any DTCs are indicated, write down the DTCs, then go to the indicated «DTC TROUBLESHOOTING»(/acura/zdx/i-2009-2013/remont/entertainment-systems/#acuralink) ; If no DTCs are indicated, refer to symptom troubleshooting. NOTE: After troubleshooting, clear the DTCs with the HDS. For specific operations, refer to the user's manual that came with the HDS.

Disconnecting

To disconnect the connector, pull the lever (A) while pushing the lock tab (B) down, then pull the connector (C).

System Description

AcuraLink® Satellite Communication System uses the client's cell phone or XM radio to transmit and receive information about the vehicle. In addition, the AcuraLink system is also able to initiate voice or data calls with the HandsFreeLink control unit.

The AcuraLink control unit (XM receiver) is very similar in design to an XM receiver, but it has additional communication features. The main functions include

Scheme 621

Scheme 621: System Description
Scheme 621: System Description
  1. Receiving and playing XM stations. Displaying station, song title and other information on the audio display using the GA-Net bus.
  2. Receiving XM traffic channel data.
  3. Receiving weather data.
  4. Gives Feature Guide tips.
  5. Receiving AcuraLink messages and displaying them in the navigation display.
  6. Processing DTC (diagnostic trouble code) error messages from the PCM, the SRS, and other systems, and displaying them on the navigation display.
  7. Sending DTC information to the AcuraLink servers using the client's cell phone (only if the client has set up and enabled this option).

Service Application

  1. Malfunction indicator lamp (MIL) explanation (from server message and vehicle message)
  2. Service information message
  3. Recall Information
  4. Quick tips
  5. Place to provide feedback/view cautions that were not available when vehicle was initially sold
  6. Correction of address and full name that is registered
  7. Real time traffic information
  8. Maintenance information message
  9. Feature guide (90 days)
  10. Weather information

The AcuraLink Satellite Communication System stores and displays these types of messages on the navigation system display screen

  1. Feature Guide info
  2. System malfunction info
  3. Driver warnings
  4. DTCs
  5. Quick tips

Note. To delete any stored AcuraLink messages, follow these procedures. The first procedure is for your client. It lets them delete certain types of messages. The second procedure is for technicians. It lets you delete all stored messages. The diagnostic menu includes a DATA RESET function. Select this only at TQI and when the vehicle changes ownership. It deletes all AcuraLink messages, log data, and AcuraLink registration. If you select DATA RESET during the 45-days activation period, the AcuraLink Feature Guide repeats the first message. AcuraLink messages related to a repair should be deleted after that repair is done. If you do not delete these messages, they stay in your client's AcuraLink message log.

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 resets 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 are available.

The AcuraLink control unit (XM receiver) has a self-diagnostic function. To run the self-diagnostic function, do the following

How to Enter the Self-Diagnostic Function

DTC B2240: XM Antenna Line Failure

  1. Connect the HDS to the DLC (see «HOW TO CHECK FOR DTCS WITH THE HDS»(/acura/zdx/i-2009-2013/remont/entertainment-systems/#acuralink__how-to-check-for-dtcs-with) ).
  2. Clear the DTC with the HDS.
  3. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, and then back to ON (II), or the ON mode and wait 30 seconds or more.
  4. Check for DTC with the HDS. Is DTC B2240 indicated? YES -Go to step 5. NO -Intermittent failure, the XM antenna is OK at this time. Check for poor connections or loose terminals at the AcuraLink control unit (XM receiver) and the XM antenna.
  5. Check the XM antenna lead connection at the AcuraLink control unit (XM receiver) and at the XM antenna. Is it connected properly? YES -Substitute a known-good AM/FM/XM antenna (see «AM/FM/XM ANTENNA REPLACEMENT»(/acura/zdx/i-2009-2013/remont/entertainment-systems/#audio-system) ), and recheck. If the symptom/indicated goes away, replace the original AM/FM/XM antenna (see «AM/FM/XM ANTENNA REPLACEMENT»(/acura/zdx/i-2009-2013/remont/entertainment-systems/#audio-system) ). If the symptom/indicated is still present, update the AcuraLink control unit (see «ACURALINK CONTROL UNIT UPDATE»(/acura/zdx/i-2009-2013/remont/entertainment-systems/#acuralink) ) if it does not have the latest software, then recheck. If the software is the latest, replace the AcuraLink control unit (XM receiver) (see «ACURALINK CONTROL UNIT (XM RECEIVER) REMOVAL/INSTALLATION»(/acura/zdx/i-2009-2013/remont/entertainment-systems/#audio-system) ). NO -Reconnect the connector, and recheck the DTC.

Scheme 635: DTC U0100: F-CAN Lost Communication with PCM
  1. Connect the HDS to the DLC (see «HOW TO CHECK FOR DTCS WITH THE HDS»(/acura/zdx/i-2009-2013/remont/entertainment-systems/#acuralink__how-to-check-for-dtcs-with) ).
  2. Clear the DTC with the HDS.

Special Tools Required

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

Note. Before you update an AcuraLink control unit (XM receiver), 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 some cases, you may damage the GNA600 or the AcuraLink control unit (XM receiver). Whenever you install a new AcuraLink control unit (XM receiver), you must update the AcuraLink control unit with the latest software. The GNA600 is the only tool currently available to update the AcuraLink control unit (XM receiver). If you are updating a AcuraLink 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 (XM receiver) with its current or previous software versions. It will only accept a new software version. Before you update the AcuraLink control unit (XM receiver), 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 AcuraLink control unit (XM receiver). 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 on-screen instructions, or if necessary, reboot the iN workstation, and try again. There are five process involved in updating the AcuraLink control unit (XM receiver): Setting up the GNA600 Capturing the current program ID from the AcuraLink control unit (XM receiver) Download the new software to the GNA600 Update the software in the vehicle's AcuraLink control unit (XM receiver) Confirm the AcuraLink self-diagnosis While updating the AcuraLink control unit (XM receiver), do not turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode. To prevent damage to the AcuraLink control unit (XM receiver), 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 (XM receiver). To update the AcuraLink control unit (XM receiver), you must connect the GNA600 to the AcuraLink connector (A), not the DLC.
