STEP 2. Check the immobilizer-ECU power supply circuit
by backprobing.
(1) Do not disconnect immobilizer-ECU connector C-107.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 7 and ground by
backprobing.
• The measured value should be approximately 12 volts
(battery positive voltage).
Q: Does the measured voltage correspond with this range?
YES : Go to Step 5.
NO : Go to Step 3.
STEP 3. Check immobilizer-ECU connector C-107 and
engine control relay connector C-59 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Are immobilizer-ECU connector C-107 and engine
control relay connector C-59 in good condition?
YES : Repair or replace them. Refer to GROUP 00E,
Harness Connector Inspection
. Confirm that
scan tool MB991958 communicates normally.
NO : Go to Step 4.

STEP 4. Check the harness wires between
immobilizer-ECU connector C-107 (terminal No. 7) and MFI
relay connector C-59 (terminal No.1).
NOTE: After checking intermediate connector C-72 and joint
connector C-14, check the wires. If intermediate connector
C-72 and joint connector C-14 are damaged, repair or replace
them. Refer to GROUP 00E, Harness Connector Inspection
.
Q: Are the harness wires between immobilizer-ECU
connector C-107 (terminal No.7) and MFI relay
connector C-59 (terminal No.1) damaged?
YES : Replace them. Confirm that scan tool MB991958
communicates normally.
NO : There is no action to be taken.

STEP 5. Check the immobilizer-ECU ground circuit by
backprobing.
(1) Do not disconnect immobilizer-ECU connector C-107.
(2) Measure the resistance between terminal 3 and ground by
backprobing.
• The measured value should be 2 ohms or less.
Q: Does the measured resistance value correspond with
this range?
YES : Go to Step 6.
NO : Go to Step 8.
STEP 6. Check immobilizer-ECU connector C-107 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is immobilizer-ECU connector C-107 in good condition?
YES : Go to Step 7.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Confirm that scan tool
MB991958 communicates normally.
STEP 7. Check the harness wire between immobilizer-ECU
connector C-107 (terminal No.3) and ground.
Q: Is the harness wire between immobilizer-ECU connector
C-107 and ground damaged?
YES : Repair it. Confirm that scan tool MB991958
communicates normally.
NO : There is no action to be taken.

STEP 8. Check the harness wires between
immobilizer-ECU connector C-107 (terminal No.5) and
powertrain control module connector C-92 (terminal
No.111).
Q: Are the harness wires between immobilizer-ECU
connector C-107 (terminal No.5) and powertrain control
module connector C-92 (terminal No.111) damaged?
YES : Repair them. Confirm that scan tool MB991958
communicates normally.
NO : Go to Step 9.
STEP 9. Replace the immobilizer-ECU or powertrain
control module.
Replace the immobilizer-ECU or powertrain control module.
Q: Did the communication with MUT-II become possible
after replacing the immobilizer-ECU or the powertrain
control module?
YES : Register the password (secret code) and encrypted
code
. Confirm that scan tool MB991958
communicates normally.
NO : Go to Step 10.
