connector (terminal No. 1) for damage or other problem.

Q:Is the wiring harness in good condition?

YES:

 Go to Step 7.

NO:

 Repair the wiring harness. Then go to Step 8.

STEP 7. Check whether the DTC is reset.

(1)

Erase the DTC.

(2)

Turn the ignition switch from the LOCK (OFF) position to the
ON position.

(3)

Check  if  the  alternator  is  correctly  operated.  (Refer  to
GROUP  16a  -  On-vehicle  Service,  Generator  Output  Line
Voltage Drop Test P.16a-6.)

(4)

Check if the DTC is set.

Q:Is the DTC No. C211F set?

YES:

 Replace AWD-ECU. (Refer to P.27C-92.) Then go to

Step 8.

NO:

 The trouble can be an intermittent malfunction.

(Refer to GROUP 00 - How to Cope with Intermittent
Malfunction P.00-15.)

STEP 8. Check whether the DTC is reset.

(1)

Erase the DTC.

(2)

Turn the ignition switch from the LOCK (OFF) position to the
ON position.

(3)

Check  if  the  alternator  is  correctly  operated.  (Refer  to
GROUP  16a  -  On-vehicle  Service,  Generator  Output  Line
Voltage Drop Test P.16a-6.)

(4)

Check if the DTC is set.

Q:Is the DTC No. C211F set?

YES:

 Diagnose again from Step 1.

NO:

 This diagnosis is complete.

DIAGNOSIS

 

If there is any problem in the CAN bus lines, an
incorrect DTC may be set. Prior to this diagnosis,
always diagnose the CAN bus lines.

OPERATION
AWD-ECU  monitors  the  coupling  solenoid  wiring
harness  abnormality  and  AWD-ECU  internal  error,
and  if  any  abnormality  occurs,  it  deactivates  the
system.

DTC SET CONDITIONS
If the following conditions are met when the system is
activated, AWD-ECU switches the control from AWD
to  FWD,  flashes  the  AWD/LOCK  indicators
alternately, and sets the DTC No. C2208.

STEP 1. Scan tool MB991958 CAN bus diagnostics
Use scan tool MB991958 to diagnose the CAN bus lines.

Q:Is the check result normal?

YES:

 Go to Step 3.

NO:

 Repair the CAN bus line. (Refer to GROUP 54D - CAN

bus diagnostic chart P.54D-17.) On completion, go to
Step 2.

STEP 2. Check whether the DTC is reset after repairing the
CAN bus line.

(1)

Erase the DTC.

(2)

Turn the ignition switch from the LOCK (OFF) position to the
ON position at least 3 times.

(3)

Use scan tool MB991958 to forcibly activate the electronic
control coupling to 10 N·m (7 ft-lb), 360 N·m (265 ft-lb), and
730  N·m  (538  ft-lb).  (Refer  to  Actuator  Test  Table  P.
27C-89.)
