DESCRIPTION AND OPERATION
COMPONENT DESCRIPTIONS - up to 99MY
Engine Control Module (ECM) - (up to 99MY)
The engine control module (ECM) prior to 99MY is a
GEMS (Generic Engine Management System), it is
located in a plastic moulded box behind the battery in
the engine compartment.
The ECM has various sensors fitted to the engine to
allow it to monitor engine condition. The ECM
processes these signals and decides what actions to
carry out to maintain driveability, after comparing the
information from these signals to mapped data within
its memory.
The black plastic case which houses the ECM
protects it from sources of contamination including
heat. The ECM itself is contained in a cast aluminium
case. The ECM has 3 independent connectors
totalling 90 pins, of which up to 66 are used,
dependent on market variations.
