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).

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:

｠

MB991223: Harness Set

｠

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)

DIAGNOSIS

(3)

Check the wiring harness between joint connector (CAN2)
C-04  (terminal  No.19)  and  ETACS-ECU  connector  C-301
(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.

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

(1)

Connect scan tool MB991958 to the data link connector.

(2)

Turn the ignition switch to the "ON" position.

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).
