STEP 5. Check the harness wire between ECM connector
C-56 terminal 61 <M/T> or PCM connector C-57 terminal 92
<A/T> and intermediate connector D-16 terminal 5 for
damage.
Q: Is the harness wire in good condition?
YES : Go to Step 22.
NO : Repair it. Then go to 22.
STEP 6. Check the 5-volt supply circuit voltage at
intermediate connector D-16.
(1) Use special tools (MB991658 and MB991709) to connect
terminals 5, 6 and 8 between connectors of the
intermediate connector D-16 respectively.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 8 and ground.
• Voltage should be between 4.9 and 5.1 volts.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the voltage normal?
YES : Go to Step 11.
NO : Remove the special tools and connect intermediate
connector D-16. Then go to Step 7.

STEP 7. Check the 5-volt supply circuit voltage at ECM
connector C-60 <M/T> or PCM connector C-54 <A/T> by
backprobing.
(1) Do not disconnect ECM connector C-60 <M/T> or PCM
connector C-54 <A/T>.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 81 <M/T> or terminal
46 <A/T> and ground by backprobing.
• Voltage should be between 4.9 and 5.1 volts.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the voltage normal?
YES : Go to Step 9.
NO : Go to Step 8.
STEP 8. Check connector C-60 at ECM <M/T> or C-54 at
PCM <A/T> for damage.
Q: Is the connector in good condition?
YES : Go to Step 21.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 10. Check the harness wire between ECM connector
C-60 terminal 81 <M/T> or PCM connector C-54 terminal 46
<A/T> and intermediate connector D-16 terminal 8 for
damage.
Q: Is the harness wire in good condition?
YES : Go to Step 22.
NO : Repair it. Then go to 22.
STEP 11. Check the circuit voltage at intermediate
connector D-16.
(1) Use special tools (MB991658 and MB991709) to connect
terminals 5 and 8 between connectors of the intermediate
connector D-16 respectively.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage at the male side connector between
terminal 6 and ground.
• The voltage should be 0.5 volt or less.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
(5) Remove the special tools and connect intermediate
connector D-16.
Q: Is the voltage normal?
YES : Go to Step 12.
NO : Go to Step 15.
