C-23

Connector: C-23

 

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
If switching the drive mode selector to FWD or LOCK
do  not  change  the  drive  mode  at  all,  AWD-ECU
detects the drive mode selector internal circuit failure,
and  switches  from  AWD  AUTO  mode  in  order  to
prevent system damage.

DTC SET CONDITIONS
If  the  following  conditions  are  met,  AWD-ECU
switches the control from AWD mode to AWD AUTO
mode, flashes the AWD/LOCK indicators alternately,
and sets the DTC No. C1460.

Intermittent malfunction of drive mode selector

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. 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 and hold there for 15 seconds.

(3)

Check that the meter display is correct when the drive mode
selector  is  switched  to  each  position  (FWD,  AWD,  and
LOCK).

DIAGNOSIS

(4)

Check if the DTC is set.

Q:Is the DTC No. C1460 set?

YES:

 Go to Step 3.

NO:

 This diagnosis is complete.

STEP 3. Scan tool MB991958 data list
Check the following service data. (Refer to P.27C-87.)

｠

Item 10: FWD SW

｠

Item 11: LOCK SW

Q:Is the check result normal?

YES:

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

NO:

 Go to Step 4.

STEP 4. Check the following connector:
Check the connectors below for improper engagement, terminal
damage or terminal drawn in the connector case.

｠

C-128 AWD-ECU connector

｠

C-23 Drive mode selector connector

｠

C-32 intermediate connector

Q:Are the connectors and terminals in good condition?

YES:

 Go to Step 5.

NO:

 Repair the connector(s) or terminal(s). Then go to

Step 10.

STEP 5. Wiring harness check
Check  the  wiring  harness  between  the  C-128  AWD-ECU
connector  and  the  C-23  drive  mode  selector  connector  for
damage or other problem.

Q:Is the wiring harness in good condition?

YES:

 Go to Step 6.

NO:

 Repair damage or other problem in the wiring harness.

Then go to Step 10.

STEP 6. Resistance measurement between the drive mode
selector connector terminals

ZC3052090001

Disconnect  the  C-23  connector,  and  measure  the  resistance
value  between  the  connector  terminals  on  the  drive  mode
selector side. (Refer to P.27C-94.)

Standard value: Continuity exists (2 Ω or less).

Q:Is  the  measured  resistance  value  within  the  standard

value range?

YES:

 Go to Step 7.

NO:

 Replace the drive mode selector. (Refer to P.

27C-93.) Then go to Step 10.

STEP 7. Voltage measurement at the AWD-ECU connector

(1)

Disconnect the C-128 AWD-ECU connector.

DIAGNOSIS

C-128 harness 
connector: 
harness side 

ZC3047200000

(2)

Measure the voltage between the C-128 wiring harness side
connector terminals No. 4 and No. 10.

OK: Battery voltage

Q:Is the check result normal?

YES:

 Go to Step 9.

NO:

 Go to Step 8.

STEP 8. Wiring harness check

｠

Wiring harness between the C-128 AWD-ECU connector and
the C-313 ETACS-ECU connector

｠

Wiring harness between the C-128 AWD-ECU connector and
the C-317 ETACS-ECU connector

Check the wiring harness above for damage or other problem.

Q:Is the wiring harness in good condition?

YES:

 Go to Step 9.

NO:

 Repair the wiring harness. Then go to Step 10.

STEP 9. Check whether the DTC is reset.

(1)

Erase the DTC.

(2)

Turn the ignition switch from the LOCK (OFF) position to the
ON position and hold there for 15 seconds.

(3)

Check that the meter display is correct when the drive mode
selector  is  switched  to  each  position  (FWD,  AWD,  and
LOCK).

(4)

Check if the DTC is set.

Q:Is the DTC No. C1460 set?

YES:

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

Step 10.
