Connector: C-01

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

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

TROUBLESHOOTING HINTS

｠

Malfunction of the connector [joint connector
(CAN3) or ASC-ECU connector improperly
connected]

｠

Malfunction of the wiring harness [open circuit
between the ASC-ECU and the joint connector
(CAN3), power supply circuit to the ASC-ECU]

｠

Malfunction of the ASC-ECU

DIAGNOSIS

Required Special Tools:

｠

MB991223: Harness Set

｠

MB992006: Extra Fine Probe

STEP 1. Check joint connector (CAN3) C-01 and ASC-ECU
connector A-02 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 (CAN3) C-01 and ASC-ECU connector

A-02 in good condition?

YES:

Go to Step 2.

NO:

Repair the damaged parts.

STEP 2. Check the wiring harness between joint connector
(CAN3) C-01 and ASC-ECU connector A-02.

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

(1)

Disconnect joint connector (CAN3) C-01 and ASC-ECU
connector A-02, and check the wiring harness.

(2)

Check the wiring harness between joint connector (CAN3)
C-01 (terminal No.6) and ASC-ECU connector A-02 (terminal
No.11)

(3)

Check the wiring harness between joint connector (CAN3)
C-01 (terminal No.19) and ASC-ECU connector A-02
(terminal No.15)

DIAGNOSIS

Q:Is the wiring harness between joint connector (CAN3)

C-01 and ASC-ECU connector A-02 in good condition?

YES:

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

to Group 35C, Troubleshooting P.35C-176.

NO:

Repair the wiring harness between joint connector

(CAN3) C-01 and ASC-ECU connector A-02.

DIAGNOSTIC ITEM 11: Diagnose when the scan tool cannot receive the data sent by
ECM.

M15408300017USA0000010000

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.
