Mitsubishi Outlander XL. Manual — part 780

ZC600880

Connector: D-106

0029

DIAGNOSTIC FUNCTION
If an open circuit is detected in the interior transmitter
antenna (rear: passenger's side), the diagnostic
trouble code is set.

JUDGEMENT CRITERIA
When the ignition push switch is pressed, or when the
antenna open circuit detection request is received
from the diagnosis function, the failure is detected.

PROBABLE CAUSES

｠

Malfunction of interior transmitter antenna
assembly (rear: passenger's side)

｠

Malfunction of the KOS-ECU

｠

Damaged wiring harness and connectors

DIAGNOSTIC PROCEDURE

STEP 1. Check KOS-ECU connector C-102 and interior
transmitter antenna assembly (rear: passenger’s side)
connector D-106 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.

Q:Are KOS-ECU connector C-102 and interior transmitter

antenna assembly (rear: passenger’s side) connector

D-106 in good condition?

YES:

Go to Step 2.

NO:

Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2.

STEP 2. Check the wiring harness between KOS-ECU
connector C-102 (terminal Nos. 6, 15 and 40) and interior
transmitter antenna assembly (rear: passenger’s side)
connector D-106 (terminal Nos. 3, 2 and 1).

NOTE:

Also check intermediate connector C-22 for loose,

corroded, or damaged terminals, or terminals pushed back in
the connector. If intermediate connectors C-22 is damaged,
repair or replace the damaged component(s) as described in
GROUP 00E, Harness Connector Inspection P.00E-2.

Q:Is the wiring harness between KOS-ECU connector C-102

(terminal Nos. 6, 15 and 40) and interior transmitter

antenna assembly (rear: passenger’s side) connector

D-106 (terminal Nos. 3, 2 and 1) in good condition?

YES:

Go to Step 3.

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 3. Keyless operation system communication test
Check that the communication with the interior transmitter
antenna assembly (rear: passenger’s side) is normal (Refer to
Antenna Test P.42B-169).

KEYLESS OPERATION SYSTEM (KOS)

DIAGNOSIS

Antennas to be checked

Rear front passenger's side antenna (interior)

OK: Normal is displayed.

Q:Is the check result normal?

YES:

Go to Step 4.

NO:

Replace the interior transmitter antenna assembly

(rear: passenger’s side).

STEP 4. Check whether the diagnostic trouble code is reset.

(1)

Erase the diagnostic trouble code.

(2)

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

(3)

Check if the diagnostic trouble code is set.

Q:Is the diagnostic trouble code set?

YES:

Replace KOS-ECU and register the ID codes (Refer

to P.42B-163).

NO:

Intermittent malfunction is suspected (Refer to

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

DTC B2412 LF antenna power voltage

M14209100030USA0000010000

｠

If diagnostic trouble code No. B2412 is set,
diagnose the CAN bus lines.

｠

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

DIAGNOSTIC FUNCTION
If KOS-ECU detects an abnormality in power supply
of the exterior or interior antennas, KOS-ECU sets
diagnostic trouble code No. B2412.

JUDGEMENT CRITERIA
If an abnormality in power supply of the exterior or
interior transmitter antenna is detected when power
supply of it is turned on, KOS-ECU determines that
there is a problem.
