FUNCTION
If a line-to-line short is present in the CAN-C lines, this
diagnosis result will be set.

TROUBLE JUDGEMENT CONDITIONS
If  only  diagnostic  trouble  code  U0001  is  set,  the
ETACS-ECU determines that there is a failure.

TROUBLESHOOTING HINTS

Malfunction  of  the  connector  (joint  connectors  or
ECU connectors improperly connected)

Malfunction of the wiring harness (line-to-line short
in the CAN-C main or sub bus lines)

Malfunction  of  the  ECU  (ECU  on  CAN-C  lines
failed)

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

MB991970: ABS Check Harness

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

DIAGNOSIS

Q:Are  joint  connector  (CAN2)  C-04  and  joint  connector

(CAN3) C-01 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 steering wheel sensor connector C-209 for
line-to-line short. Measure the resistance at joint connector
(CAN2) C-04.

Disconnect the negative battery terminal. For details refer
to P.54D-8.

A digital multimeter should be used. For details refer to P.
54D-8.

The test wiring harness should be used. For details refer
to P.54D-8.

(1)

Disconnect joint connector (CAN2), and check that there is
continuity at the harness side of joint connector (CAN2).

(2)

Check  that  there  is  continuity  between  joint  connector
(CAN2) terminals 4 and 15.

OK: No continuity

Q:Is the check result normal?

YES:

 Go to Step 3.

NO:

 Go to Step 8.

STEP 3. Check the wiring harness between joint connector
(CAN2) C-04 and AWD-ECU connector C-128 for line-to-line
short. Measure the resistance at joint connector (CAN2)
C-04.

(1)

Disconnect joint connector (CAN2), and check that there is
continuity at the harness side of joint connector (CAN2).

DIAGNOSIS

STEP 4. Check the wiring harness between joint connector
(CAN3) C-01 and ECM connector B-11 for line-to-line short.
Measure the resistance at joint connector (CAN3) C-01.

(1)

Disconnect joint connector (CAN3), and check that there is
continuity at the harness side of joint connector (CAN3).

OK: No continuity

Q:Is the check result normal?

YES:

 Go to Step 5.

NO:

 Go to Step 10.

STEP 5. Check the wiring harness between joint connector
(CAN3) C-01 and ABS-ECU connector A-01 <vehicles
without ASC> or ASC-ECU connector A-02 <vehicles with
ASC> for line-to-line short. Measure the resistance at joint
connector (CAN3) C-01.

(1)

Disconnect joint connector (CAN3), and check that there is
continuity at the harness side of joint connector (CAN3).

OK: No continuity

Q:Is the check result normal?

YES:

 Go to Step 6.

NO:

 Go to Step 11.

STEP 6. Check the wiring harness between joint connector
(CAN3) C-01 and TCM connector C-38 for line-to-line short.
Measure the resistance at joint connector (CAN3) C-01.
