Specific to:

  1. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC).
  2.  
  3. Turn the ignition switch to ON (II).
  4.  
  5. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain control module (PCM) If it does not communicate, troubleshoot the DLC circuit.
  6.  
  7. Check for DTCs. If a DTC is present, diagnose and repair the cause before continuing with this test.
  8.  
  9. Start the engine. Hold the engine speed at 3,000 rpm with no load (in N or P (A/T model) or neutral (M/T model)) until the radiator fan comes on, and then let it idle.
  10.  
  11. Check the idle speed.
  12.  
  13. Jump the SCS line with the HDS.
    NOTE
    This step must be done to protect the ECM/PCM from damage.

  14.  
  15. Connect the timing light to the service loop (white tape).
  16.  
  17. Aim the light toward the pointer on the cam chain case. Check the ignition timing under a no load condition (headlights, blower fan, rear window defogger, and air conditioner are turned off).
  18.  
  19. If the ignition timing differs from the specification, check the cam timing. If the cam timing is OK, update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, and then recheck. If the system works properly, and the ECM/PCM was substituted, replace the original ECM/PCM.
  20.  
  21. Disconnect the HDS and the timing light.
  22.
