| 1. | Connect the Honda Diagnostic System (HDS) to the data link connector (DLC). |
| 2. | Turn the ignition switch ON(II). |
| 3. | Make sure the HDS communicates with the vehicle and the ECM/PCM. If it doesn't, troubleshoot the DLC circuit. |
| 4. | Start the engine. Hold the engine at 3,000 rpm (min-1) with no load (in Neutral) until the radiator fan comes on, then let it idle. |
| 5. | Check the idle speed. |
| 6. | Select ‘‘SCS'' mode using the HDS. |
| 7. | Connect the timing light to the No. 1 ignition coil harness.
|
| 8. | Aim the light toward the pointer (A) 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).

| 9. | If the ignition timing differs from the specification, check the cam timing. If the cam timing is OK, update the engine control module (ECM)/powertrain control module (PCM) if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the system work properly, and the ECM/PCM was substituted, replace the original ECM/PCM. |
| 10. | Disconnect the HDS and the timing light. |
