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.
