STEP 3. Wiring harness check

• Wiring harness between the C-128 AWD-ECU connector

(terminal No. 16) and the C-23 drive mode selector connec-
tor (terminal No. 3)

• Wiring harness between the C-128 AWD-ECU connector

(terminal No. 14) and the C-23 drive mode selector connec-
tor (terminal No. 1)

Check the wiring harness above for damage or other problem.
Q: Is the wiring harness in good condition?

YES : Go to Step 4.
NO : Repair the wiring harness. Then go to Step 9.

STEP 4. Resistance measurement at the drive mode
selector connector
(1) Disconnect the C-23 drive mode selector connector.
(2) Measure the resistance between the C-23 wiring harness

side connector terminal No. 2 and the body ground.

OK: Continuity exists (2 ohm or less)

Q: Is the check result normal?

YES : Go to Step 6.
NO : Go to Step 5.

STEP 5. Wiring harness check
Check the wiring harness between the C-23 drive mode selec-
tor connector (terminal No.2) and the body ground for damage
or other problem.
Q: Is the wiring harness in good condition?

YES : Go to Step 8.
NO : Repair the wiring harness. Then go to Step 9.

STEP 6. Check the following connector:
Check the connectors below for improper engagement, termi-
nal damage or terminal drawn in the connector case.

• C-128 AWD-ECU connector

• C-138 intermediate connector

• C-313, C-317 ETACS-ECU connector

Q: Are the connectors and terminals in good condition?

YES : Go to Step 7.
NO : Repair the connector(s) or terminal(s). Then go to

Step 9.

STEP 7. Wiring harness check
Check the wiring harness between the C-128 AWD-ECU con-
nector (terminal No.4) and the C-313 ETACS-ECU connector
(terminal No.2) for damage or other problem.
Q: Is the wiring harness in good condition?

YES : Go to Step 8.
NO : Repair damage or other problem in the wiring

harness. Then go to Step 9.

STEP 8. Retest the system.
Q: Does the malfunction occur again?

YES : Replace AWD-ECU (Refer to

P.27C-95

). Then go to

Step 9.

NO : The trouble can be an intermittent malfunction (Refer

to GROUP 00

− How to Use Troubleshooting/How to

Cope with Intermittent Malfunctions

P.00-15

).

STEP 9. Retest the system.
Q: Does the malfunction occur again?

YES : Troubleshoot the combination meter multi information

display (Refer to GROUP 54A

−

Troubleshooting/CAN Bus Diagnostics Table

P.54A-69

). Then diagnose again from Step 1.

NO : The procedure is complete.

NOTE:

.

•

*

Tight corner braking phenomenon: When a AWD

vehicle makes sharp cornering in a paved road at
low speed (ex. parallel parking), there is a differ-
ence in turning radius between front and rear
wheels. If such a difference can no longer be
compensated by tire slippage, the vehicle
behaves as if it is under braking.

•

The vehicle is tuned so that the tight corner brak-
ing phenomenon appears at a certain level with
the drive mode selector in the LOCK position.

.

COMMENTS ON TROUBLE SYMPTOM

If the tight corner braking phenomenon occurs with
the drive mode selector being on the FWD position,
the electronic control coupling may have a problem.
If the tight corner braking phenomenon occurs only
with the drive mode selector being on the AWD posi-
tion, the data received by AWD-ECU from each ECU,
the electronic control coupling, or AWD-ECU may
have a problem.

.

TROUBLESHOOTING HINTS

• Malfunction of electronic control coupling

• Malfunction of data transmitted from ABS or ASC

system

• Malfunction of data transmitted from the engine

control system

• AWD-ECU malfunction

DIAGNOSIS

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

STEP 1. Check for the tight corner braking phenomenon
occurrence during driving on a flat road
Check if the tight corner braking phenomenon occurs during
driving on a flat road with the drive mode selector being on the
FWD or AWD position.
Q: Does the tight corner braking phenomenon occur?

YES : Go to Step 2.
NO : The procedure is complete.
