Scheme 307: 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 doesn't, troubleshoot the DLC circuit (see «DLC CIRCUIT TROUBLESHOOTING»(/acura/tl/iv-2008-2011/remont/testing-diagnostics/#pgm-fi-system__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 If no DTCs are indicated, refer to «SYMPTOM TROUBLESHOOTING»(/acura/tl/iv-2008-2011/remont/entertainment-systems/#acuralink)

Note. After troubleshooting, clear the DTCs with the HDS For specific operations, refer to the user's manual that came with the HDS

SYMPTOM TROUBLESHOOTING CHART

System Description

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

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

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-day 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 don't 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
