CAN BUS DIAGNOSTICS

DIAGNOSTIC ITEM 1: Diagnose when the scan tool cannot receive the data sent by
ETACS-ECU

M15408300006USA0000010000

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.

Connector: C-301

FUNCTION
When the CAN bus diagnosis is carried out, the scan
tool communicates with the ETACS-ECU. If a
communication flag is not set for the ETACS-ECU, the
ETACS-ECU will be diagnosed as a communication
error.

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

TROUBLESHOOTING HINTS

｠

Malfunction of the connector (data link connector or
ETACS-ECU connector improperly connected)

｠

Malfunction of the wiring harness (open circuit,
short to ground, short to power supply between the
data link connector and the ETACS-ECU
connector, line-to-line short, or power supply to the
ETACS-ECU)

｠

Malfunction of ETACS-ECU

DIAGNOSIS

Required Special Tools:

｠

MB991223: Harness Set

｠

MB992006: Extra Fine Probe

｠

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

｠

MB991824: Vehicle Communication Interface (V.C.I.)

｠

MB991827: M.U.T.-III USB Cable

｠

MB991910: M.U.T.-III Main Harness A

STEP 1. Check data link connector C-125 and ETACS-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 data link connector C-125 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 data link
connector C-125 and ETACS-ECU connector C-301.

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