Mitsubishi Outlander XL. Manual - part 774

Q:Is the DTC set?

YES:

 Replace KOS-ECU and register the ID codes. (Refer

to P.42B-12.) After registering the ID codes, go to Step
3.

NO:

 The procedure is complete.

STEP 3. Recheck for diagnostic trouble code.
Check again if the DTC is set to the KOS-ECU.

(1)

Turn the ignition switch to the "ON" position.

(2)

Check if the DTC is set.

Q:Is the DTC set?

YES:

 Replace the engine control module and record the

VIN. (Refer to GROUP 00 - How To Perform Vehicle
Identification Number (VIN) Writing P.00-26.)

NO:

 The procedure is complete.

DTC SET CONDITION
If  an  open  circuit  or  short  to  ground  occurs  in  the
antenna, KOS-ECU sets the DTC B2352.

TECHNICAL DESCRIPTION (COMMENT)
When  the  ignition  switch  is  turned  ON,  KOS-ECU
sends  signals  to  the  receiver  antenna  module.  The
receiver  antenna  transmits  random  numbers  to  the
emergency key when it receives signals from KOS-

ECU. If an open circuit or short to ground occurs on
the wiring harness between KOS-ECU and receiver
antenna at this time, KOS-ECU determines that there
is a problem.

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)

Connect scan tool MB991958. Refer to "How to connect scan
too (M.U.T.-III) P.54Af-4."

(2)

Turn the ignition switch to the "ON" position.

(3)

Check if DTC is set.

(4)

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

Q:Is the DTC B2415 is set?

YES:

 Refer to P.42B-75.

NO:

 Go to Step 2.

STEP 2. Check receiver antenna module connector C-30
and KOS-ECU connector C-102 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.

Q:Is the receiver antenna module connector C-30 and KOS-

ECU connector C-102 in good condition?

YES:

 Go to Step 3.

NO:

 Repair the defective connector.

STEP 3. Check the wiring harness between the receiver
antenna module connector C-30 (terminal No. 1, 2) and the
KOS-ECU connector C-102 (terminal No. 11, 12).

｠

Check the signal lines for open circuit and short circuit.

Q:Is the wiring harness between receiver antenna module

connector  C-30  (terminal  No.  1,  2)  and  the  KOS-ECU

connector C-102 (terminal No. 11, 12) in good condition?

YES:

 Go to Step 4.

NO:

 The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary.

STEP 4. Replace the receiver antenna module, and check
whether the diagnostic trouble code is reset.

(1)

Erase the DTC.

(2)

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

(3)

Check if the DTC is set.

Q:Is the DTC set?

YES:

 Replace KOS-ECU and register the ID codes. (Refer

to P.42B-12.)

DTC B2400: KOS key registration fail

M14209100014USA0000010000

｠

If the DTC B2400 is set, diagnose the CAN bus
lines.

｠

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

DTC SET CONDITION
If the registration of the keyless operation key ID to
KOS-ECU fails, KOS-ECU sets the DTC B2400.

TECHNICAL DESCRIPTION (COMMENT)
Assuming  that  another  keyless  operation  key  has
already  been  registered  with  KOS-ECU,  if  the

registration of the keyless operation key ID fails when
a new keyless operation key is added or the existing
key is replaced, KOS-ECU determines that there is a
problem.
