  1. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on «IF THE MIL (MALFUNCTION INDICATOR LAMP) HAS COME ON»(/acura/rsx/i-2004-2006/remont/auxiliary-emission-control-systems/#fuel-system-emissions-systems) ), and check for DTCs. If a DTC is present, diagnose and repair the cause before inspecting the ignition timing.
  2. Start the engine. Hold the engine speed at 3,000 RPM without load (in Park or Neutral) until the radiator fan comes on, then let it idle.
  3. Check the idle speed (see «IDLE SPEED INSPECTION»(/acura/rsx/i-2004-2006/remont/testing-diagnostics/#idle-control-system__idle-speed-inspection) ).
  4. Select "SCS" mode using the HDS.
  5. Connect the timing light to the service loop.
  6. Aim the light toward the pointers (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).
  7. 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 (see «HOW TO UPDATE THE ECM/PCM»(/acura/rsx/i-2004-2006/remont/auxiliary-emission-control-systems/#fuel-system-emissions-systems__how-to-update-the-ecmpcm) ), or substitute a known-good ECM/PCM (see «HOW TO SUBSTITUTE THE ECM/PCM (2002-2004 MODELS)»(/acura/rsx/i-2004-2006/remont/auxiliary-emission-control-systems/#fuel-system-emissions-systems__how-to-substitute-the-ecmpcm-2002-2004) ), then recheck. If the system works properly, and the ECM/PCM was substituted, replace the original ECM/PCM (see «ECM/PCM REPLACEMENT»(/acura/rsx/i-2004-2006/remont/testing-diagnostics/#pgm-fi-system) ).
  8. Turn the ignition switch OFF.
  9. Disconnect the HDS and the timing light.

Scheme 6: Ignition Coil Removal/Installation
  1. Remove the ignition coil cover (A), disconnect the ignition coil connectors (B), then remove the ignition coils (C).
  2. Install the ignition coils in the reverse order of removal.

  1. Check the No. 31 (15 A) fuse in the under-dash fuse/relay box. Is the fuse OK? YES - Go to step 2. NO - Replace the fuse.
  2. Remove the ignition coil relay from the under-dash fuse/relay box, and test it (see «POWER RELAY TEST»(/acura/rsx/i-2004-2006/remont/body-electrical/#relays__power-relay-test) ). Is the relay OK? YES - Go to step 3. NO - Replace the ignition coil relay.
  3. Measure the voltage between ignition coil relay 4P socket terminal No. 1 and body ground, and between terminal No. 4 and body ground. Is there battery voltage? YES - Go to step 4. NO - Replace the under-dash fuse/relay box.
  4. Check for continuity between ignition coil relay 4P socket terminal No. 2 and the No. 1, No. 2, No. 3 and No. 4 ignition coil 3P connector terminal No. 3. Is there continuity? YES - Go to step 5. NO - Repair an open in the wire between ignition coil relay 4P socket terminal No. 2 and ignition coil 3P connector terminal No. 3.
  5. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on «IF THE MIL (MALFUNCTION INDICATOR LAMP) HAS COME ON»(/acura/rsx/i-2004-2006/remont/auxiliary-emission-control-systems/#fuel-system-emissions-systems) ). Turn the ignition switch ON (II), and jump the SCS line with the HDS, then turn the ignition switch OFF. NOTE: This step must be done to protect the engine control module (ECM)/ powertrain control module (PCM) from damage.
  6. Disconnect ECM/PCM connector E (31P).
  7. Check for continuity between ignition coil relay 4P socket terminal No. 3 and body ground. Is there continuity? YES - Repair a short in the wire between ignition coil relay 4P socket terminal No. 3 and the ECM/PCM. NO - Go to step 8.
  8. Check for continuity between ignition coil relay 4P socket terminal No. 3 and ECM/PCM connector terminal E7. 2002-2004 models 2005-2006 models Is there continuity? YES - The system is OK at this time. Check for loose or poor connections at the ignition coil relay and the ECM/PCM (E7). NO - Repair an open in the wire between ignition coil relay 4P socket terminal No. 3 and the ECM/PCM (E7).

  1. Inspect the electrodes and ceramic insulator. Burned or worn electrodes may be caused by: Advanced ignition timing Loose spark plug Plug heat range too hot Insufficient cooling Fouled plug may be caused by: Retarded ignition timing Oil in combustion chamber Incorrect spark plug gap Plug heat range too cold Excessive idling/low speed running Clogged air cleaner element Deteriorated ignition coils
  2. If the spark plug electrode is dirty or contaminated, clean the electrode with a plug cleaner. NOTE: Do not use a wire brush or scrape the iridium electrode since this will damage the electrode. Use a chemical cleaner such as Carb Spray to clean contamination on the electrode. When using a sand blaster spark plug cleaner, do not clean for more than 20 seconds to avoid damaging the electrode.
  3. Do not adjust the gap of iridium tip plugs (A); replace the spark plug if the gap is out of specification.
  4. Replace the plug at the specified interval, or if the center electrode is rounded (A). Use only the spark plugs listed.
  5. Apply a small amount of anti-seize compound to the plug threads, and screw the plugs into the cylinder head, finger-tight. Then torque them. Specified Torque IFR7G11KS (NGK), SK22PR-M11S (DENSO): 25 N.m (2.5 kgf.m, 18 lbf.ft) Except IFR7G11KS (NGK), SK22PR-M11S (DENSO): 18 N.m (1.8 kgf.m, 13 lbf.ft)
