Mitsubishi Outlander XL. Manual — part 1150

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

C-01 and ECM connector B-11 in good condition?

YES:

Check the power supply circuit of the ECM. Refer to

Group 13Ab, Troubleshooting P.13Ab-807.

NO:

Repair the wiring harness between joint connector

(CAN3) C-01 and ECM connector B-11.

DIAGNOSTIC ITEM 12: Diagnose the lines between the ETACS-ECU and joint connector
(CAN2).

M15408300022USA0000010000

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
If a failure is present in the wiring harness between
the ETACS-ECU connector and the joint connector
(CAN2), this diagnosis result will be set.

TROUBLE JUDGMENT CONDITIONS
If a communication flag is not set for some of the ECUs
on the CAN-C line, the ETACS-ECU determines that
there is a failure.

TROUBLESHOOTING HINTS

｠

Malfunction of the connector [joint connector
(CAN2) or ETACS-ECU connector improperly
connected]

｠

Malfunction of the wiring harness [open circuit
between the ETACS-ECU connector and the joint
connector (CAN2), power supply circuit to the
engine control module]

｠

Malfunction of the ETACS-ECU

DIAGNOSIS

Required Special Tools:

｠

MB992006: Extra Fine Probe

STEP 1. Check joint connector (CAN2) C-04 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 joint connector (CAN2) C-04 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
(CAN2) C-04 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 (CAN2) C-04 and ETACS-ECU
connector C-301, and check the wiring harness.

(2)

Check the wiring harness between joint connector (CAN2)
C-04 (terminal No.6) and ETACS-ECU connector C-301
(terminal No.9)

(terminal No.8)

Q:Is the wiring harness between joint connector (CAN2)

C-04 and ETACS-ECU connector C-301 in good

condition?

YES:

Go to Step 3.

NO:

Repair the wiring harness between joint connector

(CAN2) C-04 and ETACS-ECU connector C-301.

STEP 3. Using scan tool MB991958, diagnose the CAN bus
line.

Diagnose CAN bus lines, and check if the scan tool screen
is as shown in the illustration.

Q:Does the scan tool 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 13: Diagnose the lines between joint connector (CAN2) and joint
connector (CAN3).
