STEP 6. Check harness connector B-11 at the crankshaft
position sensor for damage.
Q: Is the harness connector in good condition?
YES : Go to Step 7.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 10.
STEP 7. Measure the power supply voltage at ECM
connector B-11 by using power plant ECU check harness
special tool MB992110.
(1) Disconnect all ECM connectors. Connect the power plant
ECU check harness special tool MB992110 between the
separated connectors.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 117 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 : Check harness connectors C-129 and D-113 at
intermediate connector for damage, and repair or
replace as required. Refer to GROUP 00E, Harness
Connector Inspection
. If intermediate
connector is in good condition, repair harness wire
between evaporative emission ventilation solenoid
connector D-116 (terminal No. 1) and ECM connector
B-11 (terminal No. 117) because of open circuit or
short circuit to ground. Then go to Step 10.

STEP 8. Check for harness damage between MFI relay
connector A-33X (terminal No. 2) and evaporative emission
ventilation solenoid connector D-116 (terminal No. 2).
NOTE: Check harness after checking intermediate connectors
C-129 and D-113. If intermediate connectors are damaged,
repair or replace them. Refer to GROUP 00E, Harness Con-
nector Inspection
. Then go to Step 10.
Q: Is the harness wire in good condition?
YES : Go to Step 9.
NO : Repair it. Then go to Step 10.
STEP 9. Check for harness damage between evaporative
emission ventilation solenoid connector D-116 (terminal
No. 1) and ECM connector B-11 (terminal No. 117).
NOTE: Check harness after checking intermediate connector
D-113 and C-129. If intermediate connector is damaged, repair
or replace it. Refer to GROUP 00E, Harness Connector Inspec-
tion
. Then go to Step 10.
Q: Is the harness wire in good condition?
YES : Replace the ECM. When the ECM is replaced,
register the ID code. Refer to GROUP 42B, Diagnosis
− ID Code Registration Judgment Table <Vehicles
or GROUP 42C, Diagnosis
− ID
Codes Registration Judgment Table <Vehicles with
WCM>
. Then go to Step 10.
NO : Repair it. Then go to Step 10.
STEP 10. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function
− OBD-II Drive Cycle − Pattern 23
(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0446 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.
