Connectors: F-14, F-17

DIAGNOSTIC FUNCTION
If an open circuit is detected in the exterior transmitter
antenna (liftgate), 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 the exterior transmitter antenna
assembly (liftgate)

｠

Malfunction of the KOS-ECU

｠

Damaged wiring harness and connectors

DIAGNOSTIC PROCEDURE

STEP 1. Check KOS-ECU connector C-102 and exterior
transmitter antenna assembly (liftgate) connector F-14for
loose, corroded or damaged terminals, or terminals pushed
back in the connector.

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

antenna assembly (liftgate) connector D-101 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, 19 and 40) and exterior
transmitter antenna assembly (liftgate) connector F-14
(terminal Nos. 1, 2 and 3).

NOTE:

Also check intermediate connectors C-22, C-32 and

F-17 for loose, corroded, or damaged terminals, or
terminals pushed back in the connector. If intermediate
connectors C-22, C-32 and F-17 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, 19 and 40) and exterior transmitter

antenna assembly (liftgate) connector F-14(terminal Nos.

1, 2 and 3) 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 exterior transmitter
antenna assembly (liftgate) is normal (Refer to Antenna Test P.
42B-169).

KEYLESS OPERATION SYSTEM (KOS)

DIAGNOSIS

Antennas to be checked

liftgate side antenna (exterior)

OK: Normal is displayed.

Q:Is the check result normal?

YES:

Go to Step 4.

NO:

Replace the exterior transmitter antenna assembly

(liftgate).

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).
