Honda CR-V 2007-2008

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Remove the fuel fill cap, to relieve the pressure in the fuel tank.
  4.  
  5. Turn the ignition switch to ON.
  6.  
  7. From the INSPECTION MENU of the Honda Diagnostics System (HDS), select Fuel Pump OFF, then start the engine, and let it idle until it stalls.
    NOTE
    Do not allow the engine to idle above 1,000 RPM or the PCM will continue to operate the fuel pump. A DTC or a Temporary DTC may be set during this procedure. Check for DTC-s, and clear them as needed.

  8.  
  9. Turn the ignition switch to LOCK.
  10.  
  11. Perform the battery terminal disconnection procedure. Some systems store data in memory that is lost when the battery is disconnected. Do the following steps before disconnecting the battery:
    1. Make sure to record the anti-theft code(s) for the audio and/or the navigation system (if equipped).
    2.  
    3. If replacing the audio unit, write down the audio presets (AM and FM), and the XM audio presets (if equipped), because the audio unit does not retain the presets after the battery is disconnected.
    4.  
    5. Make sure the ignition switch is in LOCK position.
    6.  
    7. Disconnect and isolate the negative cable from the battery.
      NOTE
      Always disconnect the negative cable from the battery first.

  18.  
  19. Disconnect the quick-connect fitting (A): hold the connector (B) with one hand and squeeze the retainer tabs (C) with the other hand to release them from the locking tabs (D). Pull the connector off.

    Be careful not to damage the line (E) or other parts
     
    Do not use tools
     
    If the connector does not move, keep the retainer tabs pressed down, and alternately pull and push the connector until it comes off easily
     
    Do not remove the retainer from the line; once removed, the retainer must be replaced with a new one
