Q:Is the liftgate lock release handle normal?

YES:

 Go to Step 5.

NO:

 Replace the liftgate lock release handle. Check that

the liftgate lock release handle works normally.

STEP 5. KOS communication test
Using scan tool (M.U.T-III), perform the antenna communication
test to check that the exterior transmitter antenna (liftgate side)
is normal (Refer to P.42B-169).

Q:Is the check result normal?

YES:

 Go to Step 6.

NO:

 Perform troubleshooting for the diagnostic trouble

code No. B240C (Refer to P.42B-18).

STEP 6. Check of the troubles
Operate the liftgate lock release handle to check that the door
can be locked.

Q:Is the check result normal?

YES:

 Intermittent malfunction is suspected. (Refer to

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

NO:

 Replace KOS-ECU and register the ID codes (Refer

to P.42B-163).

OPERATION
The  receiver  antenna  module  receives  lock  and
unlock  signals  from  the  keyless  operation  key,  and
sends them to KOS-ECU, and further to ETACS-ECU.
Also,  when  ETACS  receives  signals  from  the  key
reminder  switch  and  all  the  door  switches,  ETACS-
ECU  judges  them  to  activate  the  keyless  entry
system.
