ENGINE CONTROL MODULE
YAD1F610
The Engine Control Module (ECM), located inside the right side kick panel, is the control center of the fuel
injection system. It constantly looks at the information fromvarious sensors and controls the systems that affect
the vehicle’s performance. Engine rpm and air mass are used to measure the air intake quantity resulting in fuel
injection metering. The ECM also performs the diagnostic functions of the system. It can recognize operational
problems, store failure code(s) which identify the problem areas to aid the technician in making repairs.
There are no serviceable parts in the ECM. The calibrations are stored in the ECM in the Programmable Read
Only Memory (PROM).
The ECM supplies either 5 or 12 volts to power the sensors or switches. This is done through resistance in the
ECM which are so high in value that a test light will not come ON when connected to the circuit. In some cases,
even an ordinary shop voltmeter will not give and accurate reading because its resistance is too low. You must
use a digital voltmeter with a 10 Mohm input impedance to get accurate voltage readings. The ECM controls
output circuits such as the ignition coils, the fuel injectors, the fuel pump relay, the camshaft actuator, the
canister purge valve, etc., by controlling the ground circuit.
