Mitsubishi Outlander (2013+). Manual - part 674
REVERSING SENSOR (CORNER SENSOR AND BACK SENSOR)
CHASSIS ELECTRICAL
54A-181
STEP 4. Diagnosis code recheck
Temporarily replace the rear corner sensor (LH), and
then check if the diagnosis code No. B253B is set.
Q: Is the diagnosis code set?
YES :
Replace the corner sensor/back
sensor-ECU.
NO :
Replace the rear corner sensor (LH).
STEP 5. Diagnosis code recheck
Temporarily replace the back sensor (RH), and then
check if the diagnosis code No. B253C is set.
Q: Is the diagnosis code set?
YES :
Replace the corner sensor/back
sensor-ECU.
NO :
Replace the back sensor (RH).
STEP 6. Diagnosis code recheck
Temporarily replace the back sensor (LH), and then
check if the diagnosis code No. B253D is set.
Q: Is the diagnosis code set?
YES :
Replace the corner sensor/back
sensor-ECU.
NO :
Replace the back sensor (LH).
Code No. U0141 ETACS CAN timeout
CAUTION
• If the diagnosis code No. U0141 is set, be sure
to diagnose the CAN bus line.
• Before replacing the ECU or sensor, ensure
that the power supply circuit, the earth circuit
and the communication circuit are normal.
• When the ETACS-ECU of vehicles without
KOS is replaced, the encrypted code of the
ignition key needs to be registered to the
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in
Immobilizer System
− How to Register Key ID
• When the illuminated licence plate is
installed, the sensors may not operate
because of noise from the plate. (When the
ultrasonic noise is received, the bass toned
buzzer sound continuously. When the ultra-
sonic noise stops, the normal operation will
be resumed immediately.)
DIAGNOSTIC FUNCTION
The corner sensor/back sensor-ECU sets diagnosis
code No.U0141 when it cannot receive signals from
the ETACS-ECU.
JUDGEMENT CRITERIA
The corner sensor/back sensor-ECU cannot receive
the signal from the ETACS-ECU via the CAN bus
line.
PROBABLE CAUSES
• Malfunction of CAN bus line
• Malfunction of ETACS-ECU
• Malfunction of corner sensor/back sensor-ECU
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-III CAN bus diagnostics
Use the M.U.T.-III to diagnose the CAN bus lines.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the CAN bus line (Refer to GROUP
54C
− Troubleshooting − CAN Bus
Diagnosis Chart ).
STEP 2. Check the M.U.T.-III Diagnosis code for
other systems
Check if the diagnosis code No. U0141 is set to
engine-ECU.
Q: Is the diagnosis code set?
YES :
Go to Step 3.
NO :
Go to Step 4.
STEP 3. Diagnosis code recheck
Check again if the diagnosis code is set to the corner
sensor/back sensor-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the LOCK (OFF)
position to the ON position.
(3) Check if the diagnosis code is set.
Q: Is the diagnosis code set?
YES :
Replace the ETACS-ECU.
NO :
A poor connection, open circuit, or other
intermittent malfunction in the CAN bus line
between the corner sensor/back
sensor-ECU and the ETACS-ECU (Refer to
GROUP 00
− How to Use
Troubleshooting/Inspection Service Points -
How to Cope with Intermittent Malfunction ).
