ECM POWER SOURCE CIRCUIT
CIRCUIT DESCRIPTION
When the ignition switch is turned to ON, the battery voltage is applied to terminal IGSW of the ECM. The
ECM ”MREL” output signal causes a current to flow to the coil, closing the contacts of the EFI relay and sup-
plying power to terminal +B of the ECM.

INSPECTION PROCEDURE
1 INSPECT ECM(+B VOLTAGE)
(a) Turn the ignition switch to ON.
(b) Measure the voltage between the terminals of the E9 and E13 ECM connectors.
Standard:
Tester ConnectionSpecified Condition
+B (E9–1) – E1 (E13–5)9 to 14 V

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester II. Freeze frame data record the engine condition\
when
malfunctions are detected. When troubleshooting, freeze frame data can h\
elp determine if the vehicle was
moving or stationary, if the engine was warmed up or not, if the air–fuel ratio was lean \
or rich, and other data
from the time the malfunction occurred.
