when checking No. 1 cylinder injector.
b. Check the harness wire between injector intermediate con-
nector B-44 (terminal No. 8) and injector connector B-33
(terminal No. 1) and injector connector B-33 (terminal No. 2)
and injector intermediate connector B-44 (terminal No. 2)
when checking No. 2 cylinder injector.
c. Check the harness wire between injector intermediate con-
nector B-44 (terminal No. 8) and injector connector B-02
(terminal No. 1) and injector connector B-02 (terminal No. 2)
and injector intermediate connector B-44 (terminal No. 1)
when checking No. 3 cylinder injector.
d. Check the harness wire between injector intermediate con-
nector B-44 (terminal No. 8) and injector connector B-35
(terminal No. 1) and injector connector B-35 (terminal No. 2)
and injector intermediate connector B-44 (terminal No. 7)
when checking No. 4 cylinder injector.
e. Check the harness wire between injector intermediate con-
nector B-44 (terminal No. 8) and injector connector B-03
(terminal No. 1) and injector connector B-03 (terminal No. 2)
and injector intermediate connector B-44 (terminal No. 6)
when checking No. 5 cylinder injector.
f. Check the harness wire between injector intermediate con-
nector B-44 (terminal No. 8) and injector connector B-11
(terminal No. 1) and injector connector B-11 (terminal No. 2)
and injector intermediate connector B-44 (terminal No. 5)
when checking No. 6 cylinder injector.
Q: Is the harness wire in good condition?
YES : Replace the injector. Then go to Step 17.
NO : Repair it. Then go to Step 17.

STEP 6. Measure the power supply voltage at injector
intermediate connector B-44.
(1) Disconnect the connector B-44 and measure at the female
connector relay side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 8 and ground.
• Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts)
present?
YES : Go to Step 8.
NO : Go to Step 7.
STEP 7. Check harness connector B-22X at MFI relay for
damage.
Q: Is the harness connector in good condition?
YES : Repair harness wire between MFI relay connector B-
22X (terminal No. 1) and intermediate connector B-44
(terminal No. 8) because of open circuit or short
circuit to ground or harness damage. Then go to Step
17.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 17.
