Mitsubishi Outlander XL. Manual — part 786

(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 KOS-ECU 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.

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 KOS-ECU. When the TPMS transmitter judges
that the portion for detecting the wheel rotation is failed, the
failure signal is send to KOS-ECU, and KOS-ECU 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 KOS-ECU

STEP 1. M.U.T.-III CAN bus diagnostics
Use scan tool to 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.
42B-12.) 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.

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)

M14209100101USA0000010000

｠

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.

DIAGNOSTIC FUNCTION
If the CAN-B circuit malfunction occurs, the
combination meter sets the DTC U0019.

JUDGMENT CRITERIA
If KOS-ECU cannot perform the data transmission in
normal conditions due to a malfunction of the CAN-B
bus circuit, KOS-ECU determines that there is a
problem.

TROUBLESHOOTING HINTS
The CAN bus line may be defective
