Accord, Odyssey & S2000
- Set parking brake. Connect tachometer. Start engine and ensure idle speed is correct. See IDLE SPEED & MIXTURE . Turn ignition off and connect scan tool to Data Link Connector (DLC). On Accord, DLC is located, behind driver's side left kick panel. See Figure. On Odyssey, DLC is located above drivers side lower heater cover. See Figure. On S2000, DLC is located under passenger side instrument panel. See Figure. On all models, follow scan tool prompts. Run engine at 3000 RPM with no electrical loads (headlights, blower motor, rear defogger, A/C and cooling fan off) and transmission in Park or Neutral. When radiator cooling fan comes on, allow engine to idle.
- Connect timing light to No. 1 ignition coil wire. Check base ignition timing with no electrical loads. See IGNITION TIMING (DEGREES BTDC - RED MARK @ RPM) table. Timing marks are located on timing belt cover (Accord and Odyssey) or timing chain cover (S2000) and crankshaft pulley. See Figure, Figure, Figure or Figure . Timing is controlled by Power Control Module (PCM). If timing is not as specified, replace PCM. See REMOVAL, OVERHAUL & INSTALLATION article. Remove scan tool.
