SYMPTOM TROUBLESHOOTING CHART

Scheme 3

Scheme 4

1. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 «HOW TO USE THE HDS (HONDA DIAGNOSTIC SYSTEM)»(/acura/mdx/ii-2006-2010/remont/testing-diagnostics/#fuel-and-emissions-systems__how-to-use-the-hds-honda) ).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the powertrain control module (PCM). If it doesn't, troubleshoot the DLC circuit (see «DLC CIRCUIT TROUBLESHOOTING»(/acura/mdx/ii-2006-2010/remont/testing-diagnostics/#pgm-fi-system__dlc-circuit-troubleshooting) ).
4. Check for DTCs (see «GENERAL TROUBLESHOOTING INFORMATION»(/acura/mdx/ii-2006-2010/remont/testing-diagnostics/#fuel-and-emissions-systems) ). If a DTC is present, diagnose and repair the cause before continuing with this test.
5. Turn the ignition switch to ON (II), select PGM-FI, and check the OIL PRESSURE SWITCH in the DATA LIST with the HDS. Is ON indicated? YES - Replace the gauge control module (see «GAUGE CONTROL MODULE REPLACEMENT»(/acura/mdx/ii-2006-2010/remont/gauges-instrument-panels/#gauges__gauge-control-module-replacement) ). NO - Go to step 6.
6. Check the oil pressure switch (see «OIL PRESSURE SWITCH TEST»(/acura/mdx/ii-2006-2010/remont/lubrication-system/#engine-lubrication) ). Is the oil pressure switch OK? YES - Go to step 7. NO - Replace the oil pressure switch (see «OIL PRESSURE SWITCH REPLACEMENT»(/acura/mdx/ii-2006-2010/remont/lubrication-system/#engine-lubrication) ).
7. 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.
8. Disconnect PCM connector C (49P) and the oil pressure switch connector.
9. 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/mdx/ii-2006-2010/remont/testing-diagnostics/#pgm-fi-system__pcm-update) ), or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(/acura/mdx/ii-2006-2010/remont/testing-diagnostics/#fuel-and-emissions-systems__substituting-the-pcm) ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM (see «PCM REPLACEMENT»(/acura/mdx/ii-2006-2010/remont/testing-diagnostics/#pgm-fi-system__pcm-replacement) ).B NO - Repair open in the wire between the oil pressure switch and the PCM.
