CAUTION / NOTICE / HINT

NOTICE:
·

Before replacing the transponder key ECU assembly or door control transmitter assembly, refer to the Service Bulletin.

·

Make sure that no DTCs are output. If any DTCs are output, proceed to the Diagnostic Trouble Code Chart.

·

After completing repairs, confirm that the problem does not recur.

·

After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".



PROCEDURE

1.CHECK REGISTRATION MODE
a.

Check that the system enters registration mode.

OK:

System enters registration mode.



Result:

5.INSPECT UNLOCK WARNING SWITCH ASSEMBLY
2.CHECK COMBINATION METER ASSEMBLY (SECURITY INDICATOR LIGHT) OPERATION
a.

In registration mode, insert the door control transmitter assembly into the ignition key cylinder and check the combination meter assembly (security indicator light).

HINT:

If the new key ID code registration fails, code 2-1 will be output through the security light. Trying to re-register an already registered door control transmitter assembly will cause code 2-2 to be output when the door control transmitter assembly is inserted. If the number of registered key ID codes exceeds the maximum limit, code 2-3 will be output through the combination meter assembly (security indicator light). The output details are shown in the following illustration.
