COMPONENT PARTS

*: Not used for engine control system.

ECM

INFOID:0000000005991040

• ECM  (Engine Control Module) controls the engine.
• ECM consists of a microcomputer and connectors for signal input

and output and for power supply.

• Battery voltage is supplied to the ECM even when the ignition

switch is turned OFF for the ECM memory function of the DTC
memory, the air-fuel ratio feedback compensation value memory,
the idle air volume learning value memory, etc.

Malfunction Indicator Lamp (MIL)

INFOID:0000000005991041

The Malfunction Indicator Lamp (MIL) is located on the combination
meter.
The MIL will illuminate when the ignition switch is turned ON without
the engine running. This is a bulb check.
When the engine is started, the MIL should turn off. If the MIL
remains illuminated, the on board diagnostic system has detected an
engine system malfunction.
For details, refer to 

EC-45, "Diagnosis Description"
