Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Test Equipment
All voltage tests should be performed with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless specifically stated differently in testing procedure.
On Accord and Prelude, when directed by testing to install Engine Control Module (ECM) test harness, turn ignition off. Connect ECM Test Harness (07LAJ-PT3010A) between ECM and ECM connector. See Fig 1 . Follow testing directions. For test harness terminal identification, see Figure . For oil pressure gauge hookup, see Fig 3 .
On Odyssey, use Backprobe Set (07SAZ-001000A) to backprobe Engine Control Module (ECM) when directed by testing. See Fig 2 . For ECM connector terminal identification, see Figure .
