ECU DIAGNOSIS
ECM
Reference ValueINFOID:0000000005398635
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 relat ed to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before m onitoring IGN TIMING, because the monitor may show the
specification data in spite of the ignition timing not bei ng 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.

ECM
*: 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. Doi ng so may result in dam-
age to the ECMs transistor. Use a ground ot her than ECM terminals, such as the ground.
COOLING FAN• Engine: After warning up, idle the
engine
• Air conditioner switch: OFF Engine coolant temperature is 98
°C
(208 °F) or less OFF
Engine coolant temperature is between
98 °C (208 °F) and 99 °C (210 °F) LOW
