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

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

TROUBLESHOOTING HINTS

｠

Malfunction  of  the  connector  [joint  connector
(CAN1),  occupant  classification-ECU  connector
improperly connected]

｠

Malfunction  of  the  wiring  harness  [open  circuit
between

 the

 occupant

 classification-ECU

connector  and  the  joint  connector  (CAN1),  power
supply circuit to the occupant classification-ECU]

｠

Malfunction of the occupant classification-ECU

DIAGNOSIS

Required Special Tools:

｠

MB991223: Harness Set

｠

MB992006: Extra Fine Probe

STEP 1. Check joint connector (CAN1) C-103, occupant
classification-ECU connector D-34, D-34-2 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

 (CAN1)

 C-103,

 occupant

classification-ECU

 connector

 D-34,

 D-34-2

 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
(CAN1) C-103 and occupant classification-ECU connector
D-31-2.

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

(1)

Disconnect  joint  connector  (CAN1)  C-103  and  occupant
classification-ECU  connector  C-301,  and  check  the  wiring
harness.

DIAGNOSIS

(2)

Check the wiring harness between joint connector (CAN1)
C-103  (terminal  No.11)  and  occupant  classification-ECU
connector D-31-2 (terminal No.24)

(3)

Check the wiring harness between joint connector (CAN1)
C-103  (terminal  No.24)  and  occupant  classification-ECU
connector D-31-2 (terminal No.25)

Q:Is  the  wiring  harness  between  joint  connector  (CAN1)

C-103 and occupant classification-ECU connector D-31-2

in good condition?

YES:

 Check the power supply circuit of the occupant

classification-ECU. Refer to Group 52B, SRS air bag
Diagnosis P.52B-306.

NO:

 Repair the wiring harness between joint connector

(CAN1) C-103 and occupant classification-ECU connector
D-31-2.

DIAGNOSTIC ITEM 19: Diagnose when the scan tool cannot receive the data sent by A/
C-ECU.

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.
