Scheme 4

Scheme 5

1. Connect the HDS to the DLC (see «GENERAL TROUBLESHOOTING INFORMATION»(/acura/tsx/ii-2008-2014/remont/testing-diagnostics/#fuel-and-emissions-systems-v6) ).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the PCM. If it does not communicate, troubleshoot the DLC circuit (see «DLC CIRCUIT TROUBLESHOOTING»(/acura/tsx/ii-2008-2014/remont/testing-diagnostics/#pgm-fi-system-v6__dlc-circuit-troubleshooting) ).
4. Check for DTCs (see «GENERAL TROUBLESHOOTING INFORMATION»(/acura/tsx/ii-2008-2014/remont/testing-diagnostics/#fuel-and-emissions-systems-v6) ). If a DTC is present, diagnose, and repair the cause before continuing with this test.
5. Start the engine, and check the OIL PRESSURE SWITCH in the PGM-FI DATA LIST with the HDS. Is ON indicated? YES -Replace the gauge control module (see «GAUGE CONTROL MODULE REPLACEMENT»(/acura/tsx/ii-2008-2014/remont/gauges-instrument-panels/#gauges-v6__gauge-control-module-replacement) ). NO -Go to step 6.
6. Turn the ignition switch to LOCK (0).
7. Check the oil pressure switch (see «OIL PRESSURE SWITCH TEST»(/acura/tsx/ii-2008-2014/remont/lubrication-system/#engine-lubrication-v6) ). Is the oil pressure switch OK? YES -Go to step 8. NO -Do the oil pressure test (see «OIL PRESSURE TEST»(/acura/tsx/ii-2008-2014/remont/lubrication-system/#engine-lubrication-v6__oil-pressure-test) ). if the oil pressure is OK, replace the oil pressure switch (see «OIL PRESSURE SWITCH TEST»(/acura/tsx/ii-2008-2014/remont/lubrication-system/#engine-lubrication-v6) ).
8. Turn the ignition switch to ON (II), and jump the SCS line with the HDS, then turn the ignition switch to LOCK (0). NOTE: This step must be done to protect the PCM from damage.
9. Disconnect PCM connector C (49P) and the oil pressure switch connector.
10. Check for continuity between PCM connector terminal C45 and the oil pressure switch connector. Is there continuity? YES -Update the PCM if it does not have the latest software (see «PCM UPDATE»(/acura/tsx/ii-2008-2014/remont/testing-diagnostics/#pgm-fi-system-v6__pcm-update) ), or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(/acura/tsx/ii-2008-2014/remont/testing-diagnostics/#fuel-and-emissions-systems-v6__substituting-the-pcm) ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM (see «PCM REPLACEMENT»(/acura/tsx/ii-2008-2014/remont/testing-diagnostics/#pgm-fi-system-v6__pcm-replacement) ).

If four numbers or marks (1 to 4 or 1 Triangle to 4 Triangles ) are printed around the outside of the filter, you can use the following procedure to tighten the filter: Spin the filter on until its seal lightly seats against the oil filter base, and note which number or mark is at the bottom. Tighten the filter by turning it clockwise three numbers or marks from the one you noted. For example, if mark Triangle is at the bottom when the seal is lightly seated, tighten the filter until the mark 4 Triangles comes around to the bottom.
7. After installation, fill the engine with oil to the specified level (see «ENGINE OIL REPLACEMENT»(/acura/tsx/ii-2008-2014/remont/lubrication-system/#engine-lubrication-v6) ), run the engine for more than 3 minutes, then check for oil leakage.
