Mitsubishi Outlander XL. Manual — part 1144
STEP 6. Check the wiring harness between joint connector
(CAN3) C-01 and TCM connector C-38 for a short to power
supply. Measure the voltage at joint connector (CAN3) C-01.
(1)
Disconnect joint connector (CAN3), and measure the voltage
at the wiring harness side of joint connector (CAN3).
(2)
Turn the ignition switch to the ON position.

Harness side: C-01
Test harness
(3)
Measure the voltage between joint connector (CAN3)
terminal 7 and body ground.
OK: 4.7 volts or less

Harness side: C-01
Test
harness
(4)
Measure the voltage between joint connector (CAN3)
terminal 20 and body ground.
OK: 4.7 volts or less
Q:Do all the voltages measure 4.7 volts or less?
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.
