STEP 5. Check connector C-59 at MFI relay for damage.
Q: Is the connector in good condition?
YES : Check connectors C-14, C-79 and E-45 at
intermediate connector for damage, and repair or
replace as required. Refer to GROUP 00E, Harness
Connector Inspection
. If intermediate
connectors are in good condition, repair harness wire
between MFI relay connector C-59 (terminal No. 1)
and evaporative emission ventilation solenoid
connector E-63 (terminal No. 1) because of open
circuit or short circuit to ground. Then go to Step 12.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 12.
STEP 6. Measure the power supply voltage at PCM
connector C-89 by backprobing.
(1) Do not disconnect the connector C-89.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 35 and ground
by backprobing.
• 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 9.
NO : Go to Step 7.

STEP 7. Check connector C-89 at PCM for damage.
Q: Is the connector in good condition?
YES : Go to Step 8.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection

STEP 8. Check for open circuit and short circuit to ground
between evaporative emission ventilation solenoid
connector E-63 (terminal No. 2) and PCM connector C-89
(terminal No. 35).
NOTE: Check harness after checking intermediate connectors
C-79 and E-45. If intermediate connectors are damaged, repair
or replace them. Refer to GROUP 00E, Harness Connector
Inspection
. Then go to Step 12.
Q: Is the harness wire in good condition?
YES : Replace the PCM. Then go to Step 12.
NO : Repair it. Then go to Step 12.
