VALUES ON THE DIAGNOSIS TOOL

NOTE:

  • The following table includes information (items) inapplicable to this vehicle. For information (items) applicable to this vehicle, refer to CONSULT display items.
  • Numerical values in the following table are reference values.
  • These values are input/output values that ECM receives/transmits and may differ from actual operations.

    Example: The ignition timing shown by the timing light may differ from the ignition timing displayed on the data monitor.

    This occurs because the timing light shows a value calculated by ECM according to signals received from the camshaft position sensor and other sensors related to ignition timing.

  • For outlines of following items.

*: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM internally.

Thus, they differ from ECM terminals voltage signal.

NOTE:

  • ECM is located in the engine room left side near battery.
  • When disconnecting ECM harness connector (A), loosen (C) it with levers as far as they will go as shown in the figure. ECM (1) Fasten (B)
  • Connect a breakout box and harness adapter between the ECM and ECM harness connector.

    Use extreme care not to touch 2 pins at one time.

    Data is for comparison and may not be exact.

  • Specification data are reference values and are measured between each terminals.
  • Pulse signal is measured by CONSULT.
