DIAGNOSIS

NO:

 Perform troubleshooting for the central door locking

system (Refer to GROUP 42Ab, Trouble symptom chart P.
42Ab-11).

STEP 4. Check the customize function.
Check that either of the followings other than "ENG strt enable"
or  "Both  disabled"  are  set  for  "KOS  feature"  with  the
customization function.

Both enable

｠

Door Entry enable

Q:Is the check result normal?

YES:

 Go to Step 5.

NO:

 Set either of the followings other than "ENG strt

enable" or "Both disabled" for "KOS feature" with the
customization function (Refer to P.42B-170).

STEP 5. Key reminder switch check.

(1)

Disconnect the C-315 ETACS-ECU connector.

(2)

Measure the resistance at the harness-side connector with
the ignition key removed from the ignition key cylinder.

Connector C-315 
(harness side)

(3)

Check  for  continuity  between  the  C-315  ETACS-ECU
connector terminal No. 13 and the ground.

OK: Continuity exists (2 Ω or less)

Q:Is the check result normal?

YES:

 Go to Step 6.

NO:

 Check the C-209 key reminder switch connector, the

C-315 ETACS-ECU connector, the wiring harness between the
C-211 key reminder switch connector (terminal No. 3) and
the C-315 ETACS-ECU connector (terminal No. 13), and
between the C-211 key reminder switch connector (terminal
No. 2) and the ground. If they are normal, replace the key
reminder switch.

STEP 6. Check with another registered keyless operation
key.

Q:Does  the  IG  knob  turn?  (Is  the  keyless  operation  key

recognised?)

YES:

 Replace the keyless operation key with which the IG

knob does not turn (no recognition) and register the ID
codes (Refer to P.42B-163).

NO:

 Go to Step 7.

STEP 7. Check of the troubles.
Operate the lock switch and check that the door can be locked
and unlocked. Also, check that the unlock sensor can lock and
unlock the door.

Q:Is the check result normal?

YES:

 The procedure is complete.

NO:

 Replace KOS-ECU and register the ID codes (Refer

to P.42B-163).
