STEP 7. Check the continuity at PCM harness side
connector D-133.
(1) Disconnect the connector D-133 and measure at the
harness side.
(2) Check for the continuity between terminal No. 33, No. 42
and ground.
• Should be less than 2 ohms.
Q: Does continuity exist?
YES : Go to Step 8.
NO : Check harness connector D-14 at intermediate
connector for damage, and repair or replace as
required. Refer to GROUP 00E, Harness Connector
Inspection
. If intermediate connector D-14 is
in good condition, repair an open circuit or harness
damage between PCM connector D-133 (terminal No.
33, No. 42) and ground. Then confirm that the
malfunction symptom is eliminated.

STEP 8. Measure the power supply voltage at PCM harness
side connector D-133.
(1) Disconnect the connector D-133 and measure at the
harness side.
(2) Measure the voltage between terminal No.57 and ground.
• Voltage should be battery positive voltage.
Q: Is battery positive voltage (approximately 12 volts)
present?
YES : Go to Step 9.
NO : Repair an open circuit between MFI relay connector
B-22X (terminal No. 4) and PCM connector D-133
(terminal No. 57). Then confirm that the malfunction
symptom is eliminated.

STEP 9. Measure the power supply voltage at PCM harness
side connector D-133.
(1) Disconnect the connector D-133 and measure at the
harness side.
(2) Using a jumper wire, connect terminal No. 57 to ground.
(3) Measure the voltage between terminal No. 34, No. 43 and
ground.
• Voltage should be battery positive voltage.
Q: Is battery positive voltage (approximately 12 volts)
present?
YES : Replace the PCM. Then confirm that the malfunction
symptom is eliminated.
NO : Check harness connector D-116 at intermediate
connector for damage, and repair or replace as
required. Refer to GROUP 00E, Harness Connector
Inspection
. If intermediate connector D-116
is in good condition, repair an open circuit between
MFI relay connector B-22X (terminal No. 1) and PCM
connector D-133 (terminal No. 34, No. 43). Then
confirm that the malfunction symptom is eliminated.
