FUNCTION
If a failure is present in the wiring harness between
the  joint  connector  (CAN2)  and  the  joint  connector
(CAN3), this diagnosis result will be set.

TROUBLE JUDGEMENT CONDITIONS
If a communication flag is not set for some of the ECUs
on the CAN-C line, the ETACS-ECU determines that
there is a failure.

TROUBLESHOOTING HINTS

｠

Malfunction  of  the  connector  [joint  connector
(CAN2),  joint  connector  (CAN3)  or  intermediate
connector failed]

｠

Malfunction  of  the  wiring  harness  [open  circuit
between joint connector (CAN2) and joint connector
(CAN3)]

DIAGNOSIS

Required Special Tools:

｠

MB991223: Harness Set

｠

MB992006: Extra Fine Probe

STEP 1. Check joint connector (CAN2) C-04, joint connector
(CAN3) C-01 and intermediate connector C-33 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, joint connector (CAN3)

C-01 and intermediate connector C-33 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 joint connector (CAN3) C-01.

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

(1)

Disconnect joint connector (CAN2) C-04 and joint connector
(CAN3) C-01, and check the wiring harness.

(2)

Check the wiring harness between joint connector (CAN2)
C-04  (terminal  No.6)  and  joint  connector  (CAN3)  C-01
(terminal No.5)

DIAGNOSIS

(3)

Check the wiring harness between joint connector (CAN2)
C-04  (terminal  No.19)  and  joint  connector  (CAN3)  C-01
(terminal No.16)

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

C-04 and joint connector (CAN3) C-01 in good condition?

YES:

 The trouble can be an intermittent malfunction

(Refer to GROUP 00, How to use Troubleshooting/inspection
Service Points - How to Cope with Intermittent
Malfunction P.00-15).

NO:

 Repair the wiring harness between joint connector

(CAN2) C-04 and joint connector (CAN3) C-01.

DIAGNOSTIC ITEM 14: Diagnose when the scan tool cannot receive the data sent by
combination meter.

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.
