Vehicle Side : No. 1-12

Engine Side : No. 61-72

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.
