SRS Unit Update
Special Tools Required
  • Honda diagnostic system (HDS) table tester
  • Honda interface module (HIM) and an iN workstation with HDS and CM update software
  • HDS pocket tester
  • GNA600 and an iN workstation with HDS and CM update soft ware (Any one of the update tools above will work)
NOTE:
  • Use this procedure when you need to update the SRS unit at anytime.
  • Make sure the HDS/HIM has the latest software version.
  • Before you update the SRS unit, make sure the battery in the vehicle is fully charged.
  • Never turn the ignition switch to LOCK (0) or ACC (I) during the update. If there is a problem with the update, leave the ignition switch in the ON (II).
  • To prevent SRS unit damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, moonroof (if equipped), door locks, etc.) during the update.
  • To ensure the latest program is installed, do an SRS unit update whenever the SRS unit is replaced.
  • You cannot update an SRS unit with a program it already has. It will only accept a new program.
  • If you need to diagnose the HIM because the HIM's red (#3) light came on or was flashed during the update, leave the ignition switch in the ON (II) position when you disconnect the HIM from the data link connector (DLC). This will prevent SRS unit damage.
  1. Connect the HDS to the DLC (A).
  1. Turn the ignition switch to ON (II), but do not start the engine.
  1. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit.
  1. Select the update program, and follow the screen prompts to update the SRS unit.
  1. If the software in the SRS unit is the latest, disconnect the HDS/HIM from the DLC, and go back to the procedure that you were doing. If the software in the SRS unit is not the latest, follow the instructions on the screen.
    NOTE: If you run into a problem during the update procedure (programming takes over 15 minutes, status bar goes over 100 %, D or immobilizer light flashes, HDS tablet freezes, etc.), follow these steps to minimize the chance of damaging the SRS unit :
    • Leave the ignition switch in the ON (II) position.
    • Connect a jumper battery (do not connect a battery charger).
    • Shut down the HDS.
    • Disconnect the HDS from the DLC.
    • Reboot the HDS.
    • Reconnect the HDS to the DLC, and try the update procedure again.
