Is an ignition coil DTC indicated at the exchanged cylinder position?
YES: Replace the faulty ignition coil (see IGNITION COIL REMOVAL/INSTALLATION ), then go to step 25.
NO: Go to step 9.
- Turn the ignition switch to LOCK (0).
- Check the No. 33 IGNITION COIL (15 A) fuse in the under-dash fuse/relay box.
Is the fuse OK?
YES: Go to step 11.
NO: Go to step 12.
- Open the fuse access panel (A), then test the ignition coil relay (B) in the under-dash fuse/relay box (see REMOVAL AND INSTALLATION
).
Is the ignition coil relay OK?
YES: Go to step 15.
NO: Replace the ignition coil relay, then go to step 25.
- Open the fuse access panel (A), then remove the ignition coil relay (B) from the under-dash fuse/ relay box.
- Disconnect all ignition coil 3P connectors.
- Check for continuity between No. 1 ignition coil 3P connector terminal No. 3 and body ground.
Is there continuity?
YES: Repair short in the wire between the ignition coils and the ignition coil relay. Also replace the No. 33 IG COIL (15 A) fuse, then go to step 25.
NO: Check the under-dash fuse/relay box, and replace it if needed (see REMOVAL AND INSTALLATION ), then go to step 25.
- Reinstall the ignition coil relay.
- Disconnect the ignition coil 3P connector from the problem cylinder.
- Turn the ignition switch to ON (II).
- Measure the voltage between ignition coil 3P connector terminal No. 3 of the problem cylinder and body ground (see table below).DTC TABLE
PROBLEM CYLINDER DTC No. 1 P0351 No. 2 P0352 No. 3 P0353 No. 4 P0354 Is there battery voltage?
YES: Go to step 19.
NO: Repair open in the wire between the ignition coil and the ignition coil relay, then go to step 25.
- Turn the ignition switch to LOCK (0).
- Check for continuity between ignition coil 3P connector terminal No. 2 of the problem cylinder and body ground (see table below).DTC TABLE
PROBLEM CYLINDER DTC No. 1 P0351 No. 2 P0352 No. 3 P0353 No. 4 P0354 Is there continuity?
YES: Go to step 21.
NO: Repair open in the wire between the ignition coil and G101; M/T model (see CONNECTOR TO HARNESS INDEX ), A/T model (see CONNECTOR TO HARNESS INDEX ), then go to step 25.
- Jump the SCS line with the HDS.
- Disconnect ECM/PCM connector C (49P).
- Check for continuity between body ground and the appropriate ECM/PCM connector terminal of the problem cylinder (see table below).DTC TABLE
PROBLEM CYLINDER DTC ECM/PCM TERMINAL WIRE COLOR No. 1 P0351 C15 WHT No. 2 P0352 C16 WHT/GRN No. 3 P0353 C17 WHT/BLK No. 4 P0354 C18 WHT/BLU Is there continuity?
YES: Repair short in the wire between the ECM/PCM and the ignition coil, then go to step 25.
NO: Go to step 24.
- Check for continuity between appropriate ignition coil 3P connector terminal No. 1 and the appropriate ECM/PCM connector terminal of the problem cylinder (see table below).DTC TABLE
PROBLEM CYLINDER DTC ECM/PCM TERMINAL WIRE COLOR No. 1 P0351 C15 WHT No. 2 P0352 C16 WHT/GRN No. 3 P0353 C17 WHT/BLK No. 4 P0354 C18 WHT/BLU Is there continuity?
YES: Go to step 31.
NO: Repair open in the wire between the ECM/PCM and the ignition coil, then go to step 25.
- Turn the ignition switch to LOCK (0).
- Reconnect all connectors.
- Turn the ignition switch to ON (II).
- Reset the ECM/PCM with the HDS.
- Do ECM/PCM IDLE LEARN PROCEDURE .
- Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0351, P0352, P0353, and/or P0354 indicated?
YES: Check for poor connections or loose terminals at the ignition coil and the ECM/PCM, then go to step 1.
NO: Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
- Reconnect all connectors.
- Update the ECM/PCM if it does not have the latest software (see ECM/PCM UPDATE ), or substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).
- Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0351, P0352, P0353, and/or P0354 indicated?
YES: Check for poor connections or loose terminals at the ignition coil and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the ECM/PCM was substituted, go to step 1.
NO: If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
