Mitsubishi Outlander XL. Manual - part 821

 

 

YES:

 Go to Step 5.

NO:

 Replace it. Then go to Step 7.

STEP 5. Tire pressure check by M.U.T.-III

(1)

Check  the  registered  ID  code  by  the  transmitter  ID  check
function.

(2)

Check the wheel to which the DTC is set by the transmitter
check function.

(3)

Using the M.U.T.-III, check the relevant tire pressure.

(4)

Using the tire pressure gauge, check the tire pressure at the
air  valve  of  relevant  tire.  Then,  measure  the  difference
between  that  checked  tire  pressure  and  the  tire  pressure
displayed at the procedure (3).

OK: 20 kPa or less

Q:Is the check result normal?

YES:

 Go to Step 6.

NO:

 Replace the TPMS transmitter and register the ID

codes. (refer to P.42C-8.) Then go to Step 7.

STEP 6. Tire pressure check by M.U.T.-III

(1)

Check  the  registered  ID  code  by  the  transmitter  ID  check
function.

(2)

Check the wheel to which the DTC is set by the transmitter
check function.

(3)

Using the M.U.T.-III, check the relevant tire pressure.

(4)

Using the tire pressure gauge, check the tire pressure at the
air  valve  of  relevant  tire.  Then,  measure  the  difference
between  that  checked  tire  pressure  and  the  tire  pressure
displayed at the procedure (3).

OK: 20 kPa or less

Q:Is the check result normal?

YES:

 Go to Step 7.

NO:

 Replace the WCM and register the ID codes. (refer

to P.42C-8.) Then go to Step 7.

STEP 7. Recheck for diagnostic trouble code.

(1)

Correct the tire pressure for all wheels.

(2)

Turn the ignition switch to the "LOCK" (OFF) position.

(3)

Turn the ignition switch to the "ON" position.

(4)

Check if the DTC is set.

(5)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is  the  diagnostic  trouble  code  C1912,  C1922,  C1932  or

C1942 set?

YES:

 Start over at Step 1.

NO:

 The procedure is complete.

DTC C1913: Acceleration Sensor Abnormality 1
DTC C1923: Acceleration Sensor Abnormality 2
DTC C1933: Acceleration Sensor Abnormality 3

WIRELESS CONTROL MODULE (WCM)

42C-43

DIAGNOSIS

DTC C1943: Acceleration Sensor Abnormality 4

M14209200064USA0000010000

If there is any problem in the CAN bus lines, an incorrect
diagnostic trouble code may be set. Prior to this diagnosis,
diagnose the CAN bus lines. (Refer to GROUP 54D, Trouble
code diagnosis P.54D-17
).

TPMS DTC SET CONDITION
The TPMS transmitter detects if the wheel is rotated and sends
the signals to WCM. When the TPMS transmitter judges that the
portion for detecting the wheel rotation is failed, the failure signal
is sent to WCM, and WCM sets this code.

TROUBLESHOOTING HINTS
The most likely causes for this DTC to set are:

Damaged wiring harness and connector

Malfunction of TPMS transmitter

Malfunction of WCM

DIAGNOSIS

Required Special Tools:

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

MB991824: Vehicle Communication Interface (V.C.I.)

MB991827: M.U.T.-III USB Cable

MB991910: M.U.T.-III Main Harness A

STEP 1. M.U.T.-III CAN bus diagnostics
Use scan tool MB991958, diagnose the CAN bus lines.

Q:Is the check result normal?

YES:

 Check the registered ID by the transmitter ID check

function, and detect the wheel to which the DTC is set by
the transmitter check function. Then, replace the TPMS
transmitter, and register the ID codes. (Refer to P.
42C-8.) Then go to Step 3.

NO:

 Repair the CAN bus lines. (Refer to GROUP 54D - CAN

Bus Diagnostics table P.54D-17.) On completion, go to
Step 2.

STEP 2. Diagnostic trouble code recheck after resetting
CAN bus lines.

(1)

Turn the ignition switch to the "ON" position.

(2)

Check if the DTC is set.

(3)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is  the  diagnostic  trouble  code  C1913,  C1923,  C1933  or

C1943 set?

YES:

 Start over at Step 1.

NO:

 The procedure is complete.

DIAGNOSIS

STEP 3. Recheck for diagnostic trouble code.

(1)

Turn the ignition switch to the "LOCK" (OFF) position.

(2)

Turn the ignition switch to the "ON" position.

(3)

Check if the DTC is set.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is  the  diagnostic  trouble  code  C1913,  C1923,  C1933  or

DTC U0019: Bus off(CAN-B)

M14209200024USA0000010000

If DTC U0019 is set, be sure to diagnose the CAN
bus line.

When replacing the ECU, always check that the
communication circuit is normal.

DTC SET CONDITION
If the CAN-B circuit malfunctions, the WCM sets DTC
U0019.

TECHNICAL DESCRIPTION(COMMENT)
If  WCM  cannot  perform  the  data  transmission  in
normal conditions due to a malfunction of the CAN-B
bus circuit, WCM determines that there is a problem.

TROUBLESHOOTING HINT
The CAN bus line may be defective
