Mitsubishi Outlander XL. Manual - part 816

STEP 2. Check if VIN registered in the engine control
module matches with the vehicle's VIN.
Check if VIN registered in the engine control module matches
with the vehicle's VIN.

Q:Does  the  VIN  registered  in  the  engine  control  module

match the vehicle's VIN?

YES:

 Go to Step 3.

NO:

 Replace the engine ECU and record VIN (Refer to GROUP

00 - How to Perform Vehicle Identification Number (VIN)
Writing P.00-26). Record VIN and go to Step 3.

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

(1)

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

(2)

Check if the DTC is set.

Q:Is the DTC set?

YES:

 Replace WCM and register the ID codes. (Refer to P.

42C-8.)

NO:

 Intermittent malfunction is suspected. (Refer to

GROUP 00 - How to Use Troubleshooting/Inspection Service
Points - How to Deal with Intermittent Malfunction P.
00-15.)

DTC B1A35: Transponder read error

M14209200017USA0000010000

｠

When DTC B1A35 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
WCM sets DTC B1A35 when it cannot receive data
from the transponder.

TECHNICAL DESCRIPTION (COMMENT)
WCM determines that the abnormality is present, if it
cannot receive the encrypted code for the ignition key
when the ignition switch is turned ON.

DIAGNOSIS

STEP 1. Using scan tool MB991958, diagnose the CAN bus
line.

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 to the data link connector.

(2)

Turn the ignition switch to the "ON" position.

(3)

Diagnose the CAN bus line.

(4)

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

Q:Is the CAN bus line found to be normal?

YES:

 Go to Step 2.

NO:

 Repair the CAN bus line. (Refer to GROUP 54D,

Diagnosis P.54D-17).

STEP 2. Check the ignition key inserted in the key cylinder
for interference.

Q:Are there other ignition keys or anything that interferes

with  the  communication  (things  that  generate  radio

waves such as magnets or air-cleaning device that has a

power  plug)  near  the  ignition  key  inserted  in  the  key

cylinder?

YES:

 Move away or remove other ignition keys or anything

that interferes with the communication, and go to Step 3.

NO:

 Go to Step 3.

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

(1)

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

(2)

Check if the DTC is set.

Q:Is the DTC set?

YES:

 Go to Step 4.

NO:

 The procedure is complete.

STEP 4. Replace the ignition key and recheck the diagnostic
trouble code.
Replace the ignition key by which the DTC is set with a new one,
register the encrypted code of the new key, (refer to P.42C-8),
and recheck if the DTC is set.

(1)

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

(2)

Check if the DTC is set.

Q:Is the diagnostic trouble code set?

WIRELESS CONTROL MODULE (WCM)

DIAGNOSIS

YES:

 Replace WCM and register the ID codes. (Refer to P.

42C-8.)

NO:

 The procedure is complete.

｠

If  DTC  B2101  or  B2102  is  set,  be  sure  to
diagnose the CAN bus line.

｠

Before  replacing  the  ECU,  ensure  that  the
communication circuit is normal.

DTC SET CONDITION
WCM sets DTC B2101 or B2012 when the actual state
of the ignition switch and the ignition switch position
information received from ETACS-ECU via CAN do
not match.

TECHNICAL DESCRIPTION (COMMENT)
WCM determines that the abnormality is present, if it
has detected discrepancy in the ignition switch level
shown below ten consecutive times when WCM has
received the CAN message (ignition switch position
information) from ETACS-ECU with the ignition switch
turned to the ON or START position.
