FUNCTION
If the scan tool MB991958 cannot communicate with
the AWD-ECU, this diagnosis result will be set.

TROUBLE JUDGEMENT CONDITIONS
If a communication flag is not set for the AWD-ECU,
the ETACS-ECU determines that there is a failure.

TROUBLESHOOTING HINTS

｠

Malfunction  of  the  connector  [joint  connector
(CAN2)  or  AWD-ECU  connector  improperly
connected]

｠

Malfunction  of  the  wiring  harness  [open  circuit
between  the  AWD-ECU  and  the  joint  connector
(CAN2), power supply circuit to the AWD-ECU]

｠

Malfunction of the AWD-ECU

DIAGNOSIS

Required Special Tools:

｠

MB991223: Harness Set

｠

MB992006: Extra Fine Probe

STEP 1. Check joint connector (CAN2) C-04, AWD-ECU
connector C-128 and intermediate connector C-31 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

The strand end of the twisted wire should be within 10 cm
(4 inches) from the connector. For details refer to P.54D-8.

Q:Are  joint  connector  (CAN2)  C-04,  AWD-ECU  connector

C-128  and  intermediate  connector  C-31  in  good

condition?

YES:

 Go to Step 2.

NO:

 Repair the damaged parts.

STEP 2. Check the wiring harness between joint connector
(CAN2) C-04 and AWD-ECU connector C-128.

Strictly  observe  the  specified  wiring  harness  repair
procedure. For details refer to P.54D-8.

(1)

Disconnect  joint  connector  (CAN2)  C-04  and  AWD-ECU
connector C-301, and check the wiring harness.

(2)

Check the wiring harness between joint connector (CAN2)
C-04  (terminal  No.5)  and  AWD-ECU  connector  C-128
(terminal No.5)

DIAGNOSIS

(3)

Check the wiring harness between joint connector (CAN2)
C-04  (terminal  No.16)  and  AWD-ECU  connector  C-128
(terminal No.13)

Q:Is  the  wiring  harness  between  joint  connector  (CAN2)

C-04 and AWD-ECU connector C-128 in good condition?

YES:

 Check the power supply circuit of the AWD-ECU. Refer

to Group 27C, Multiselect AWD Diagnosis P.27C-74.

NO:

 Repair the wiring harness between joint connector

(CAN2) C-04 and AWD-ECU connector C-128.

DIAGNOSTIC ITEM 7: Diagnose when the scan tool cannot receive the data sent by
steering wheel sensor.

M15408300012USA0000010000

When servicing a CAN bus line, ground yourself
by touching a metal object such as an unpainted

water  pipe.  If  you  fail  to  do  so,  a  component
connected to the CAN bus line may be damaged.
