Mitsubishi Outlander XL. Manual — part 1141

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

(1)

Disconnect joint connector (CAN3), and measure the
resistance at the wiring harness side of joint connector
(CAN3).

ZC5010410012

Harness side: C-01

Test harness

(2)

Measure the resistance between joint connector (CAN3)
terminal 7 and body ground.

OK: 1 kiloohm or more

ZC5010410013

Harness side: C-01

Test
harness

(3)

Measure the resistance between joint connector (CAN3)
terminal 20 and body ground.

OK: 1 kiloohm or more

Q:Do all the resistances measure 1 kiloohm or more?

YES:

Check intermediate connector C-27, and repair if

necessary. If the intermediate connector is in good
condition, repair the wiring harness between joint
connector (CAN2) C-04 and joint connector (CAN3) C-01.

NO:

Go to Step 12.

STEP 7. Using scan tool MB991958, diagnose the CAN bus
line. (checking the steering wheel sensor for internal short
to ground)

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
connecting or disconnecting scan tool MB991958.

(1)

Disconnect steering wheel sensor connector C-209.

shown in the figure.

Q:Does scan tool MB991958 screen correspond to the

illustration?

YES:

Repair the wiring harness between steering wheel

sensor connector C-209 and joint connector (CAN2) C-04.

NO:

Check steering wheel sensor connector C-209, and

repair if necessary. If the steering wheel sensor
connector is in good condition, replace the steering
wheel sensor.

STEP 8. Using scan tool MB991958, diagnose the CAN bus
line. (checking the AWD-ECU for internal short to ground)

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
connecting or disconnecting scan tool MB991958.

(1)
