Reference ValueINFOID:0000000001161405
VALUES ON THE DIAGNOSIS TOOL
Remarks:
 Specification data are reference values.
 Specification data are output/input values which are detected or supplied by the ECM at the connector.
*Specification data may not be directly related to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the
specification data in spite of the ignition timing not being adjusted to the specification data. this IGN TIMING
monitors the data calculated by the ECM according to the signals input from the camshaft position sensor and
other ignition timing related sensors.
Monitor Item Condition Values/Status
ENG SPEED  Run engine and compare CONSULT-III value with the tachometer indication.Almost the same speed as
the tachometer indication.

*: 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.
TERMINAL LAYOUT
PHYSICAL VALUES
NOTE:
 ECM is located in the engine room left side near battery.
 Specification data are reference values and are measured between each terminal and ground.
 Pulse signal is measured by CONSULT-III.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECMs transistor. Use a ground other than ECM terminals, such as the ground.
