Terminal Resistance And Continuity Check

  1. Turn the ignition switch to OFF.
  2. Disconnect the PCM connector.
  3. Measure the resistance and check for continuity between the terminals of the PCM harness-side connector while referring to the check chart.
    NOTE:
    • When measuring resistance and checking continuity, a harness for checking connect pin pressure should be used instead of inserting a test probe.
    • Checks do not have to be carried out in the order given in this chart.
    CAUTION: If resistance or continuity checks are performed on the wrong terminals, damage to the vehicle wiring, sensors, PCM, and/or ohmmeter may occur. Use care to prevent this!
  4. If the ohmmeter shows any deviation from the normal condition, check the corresponding sensor, actuator and related electrical wiring, and then repair or replace.
  5. After repair or replacement, recheck with the ohmmeter to confirm that the repair or replacement has corrected the problem.
