FUNCTION
If  a  failure  is  present  in  the  wiring  harness  wires
between  the  ETACS-ECU  connector,  the  joint
connector  (CAN1),  the  ETACS-ECU  connector  and
the joint connector (CAN1), this diagnosis result will
be set.

TROUBLE JUDGEMENT CONDITIONS
If a communication flag is set for none of the ECUs on
the CAN-B line, the ETACS-ECU determines that
there is a failure.

｠

MB992006: Extra Fine Probe

STEP 1. Check joint connector (CAN1) C-103 and EATCS-
ECU connector C-301 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 and ETACS-ECU

connector C-301 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 ETACS-ECU connector C-301.

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

(1)

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

DIAGNOSIS

(2)

Check the wiring harness between joint connector (CAN1)
C-103 (terminal No.6) and ETACS-ECU connector C-301
(terminal No.6)

(3)

Check the wiring harness between joint connector (CAN1)
C-103 (terminal No.17) and ETACS-ECU connector C-301
(terminal No.7)

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

C-103 and ETACS-ECU connector C-301 in good

condition?

YES:

Go to Step 3.

NO:

Repair the wiring harness between joint connector

(CAN1) C-103 and ETACS-ECU connector C-301.

STEP 3. Using scan tool MB991958, diagnose the CAN bus
line. (trouble symptom check)

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

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before

OK: The display of the scan tool MB991958 is as
shown in the figure.

Q:Does scan tool MB991958 screen correspond to the

illustration?

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:

Replace the ETACS-ECU.

DIAGNOSTIC ITEM 26: Short to power supply or ground, open circuit or line-to-line
short in the CAN-B bus lines.
