6-42 ENGINE GENERAL INFORMATION AND DIAGNOSIS (G16/J20 ENGINES)

Inspection of PCM (ECM) and Its Circuits

PCM (ECM) and its circuits can be checked at PCM (ECM) wiring
couplers by measuring voltage, pulse signal and resistance.

VOLTAGE CHECK

1) Remove PCM (ECM) cover from bracket referring to “Engine

Control Module (ECM)/Powertrain Control Module (PCM)” in
Section 6E1.

2) Check voltage at each terminal of couplers connected, using

voltmeter (1) and oscilloscope (2).

CAUTION:

PCM/ECM cannot be checked by itself. It is strictly pro-
hibited to connect voltmeter or ohmmeter to PCM (ECM)
with couplers disconnected from it.

NOTE:

• As each terminal voltage is affected by the battery volt-

age, confirm that it is 11 V or more when ignition
switch is ON.

• Voltage with asterisk (*) cannot be measured by volt-

meter because it is pulse signal.

• Check it with oscilloscope if necessary.
