transmitters. When registering two transmitters, register them successively following the proceduresgiven below.

3.If a new transmitter is registered, all the former identification codes registered in the receiver will beerased.

4.The memory of the identification code will not be lost even if the battery is disconnected.1-5-2 HOW TO REGISTER IDENTIFICATION CODE



(1) VEHCLE IN AN INITIAL REGISTRATION CONDITION1.The initial condition refers to the condition that satisfies the following given below.

(1) No key is inserted into the key cylinder.(2) The battery negative terminal or receiver connector is disconnected.

1-5 HOW TO PROCEED WITH TROUBLE SHOOTING1.The immobilizer system is equipped with a diagnosis function which diagnoses malfunctioning

sections and gives important clues in the trouble shooting.2.The diagnosis function of the immobilizer system is equipped with the battery backup. (Which keeps

supplying power for diagnosis memory even when the ignition switch is set to LOCK position.)

1-6 INQUIRY1.In an effort to remove causes for malfunction from the vehicle concerned, it is impossible to determine

the cause without confirming the malfunction phenomenon. If the phenomenon is not confirmed, thevehicle may not be able to return to the normal conditions even if you continue your work. Thediagnosis through inquiries is to collect information from the customer before confirming themalfunction phenomena. The diagnosis through inquiries provides very important clues inreproducing malfunction phenomena.

2.Since the information obtained by the diagnosis through inquiries is referred to during the troubleshooting, it is imperative to make an inquiry of the customer, centering on the items related to themalfunction, instead of simply asking general questions.

1-7 DIAGNOSIS1-7-1 OUTLINE1.When the diagnosis code is indicated, confirm whether the malfunction took place sometimes in the

system or is still persisting. Also it is necessary to check any relation between the code and thereproduced malfunction. For this purpose, the diagnosis code should be indicated twice, namelybefore and after the confirmation of the phenomena.

1-7-2 CHECKING METHOD OF DIAGNOSIS1.Connect the SST to between the terminal BAT' and terminal W of the diagnosis check connector

located under the instrument panel. Connect the terminal ECUT and terminal E and start thediagnosis check mode. The SST lamp will flash, thus indicating the diagnosis code.SST: 09991-87403-000

09991-97201-000

I4–32

2.All the diagnosis codes memorized are shown repeatedly in the sequence of diagnosis number,starting from the smallest number.

CAUTION• The SST lamp section uses a light emitting diode. Therefore, connect the "red" wire of the SST to

the terminal "BAT" of the diagnosis check connector; the "black" wire of the SST to the terminal "W"of the connector.

1-7-3 CANCELING METHOD OF DIAGNOSIS1.When the section which is responsible for the malfunction code has been checked and repaired,

erase the memory, following the procedure given below. After the erasure, let the diagnosis code beoutputted again and confirm that the normal code is outputted.

CAUTION• The code No.12 will be erased even when the normal main key (Registered main key) is used.• The diagnosis codes No. 23 and No. 31 are not memorized.

(1) ERASURE BY DISCONNECTING EFI FUSE1.The memorized diagnosis code can be erased by setting the ignition knob to the "LOCK" position and

disconnecting the "hazard fuse" for at least 30 seconds. NOTE• The "hazard fuse" is located inside the engine compartment (Relay box).• The codes can be erased usually in about 30 seconds, but in some cases it may take more than 30

seconds.


systems or radio settings are erased at the same time when the battery negative terminal of thebattery is disconnected.
