CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the
scan tool (GROUP 00, How to Cope with Intermittent
Malfunction

P.00-15

).

.

When detecting fault and storing the DTC, the ECU
connected to CAN bus line obtains the data before
the determination of the DTC and the data when the
DTC is determined, and then stores the ECU status
of that time. By analyzing each data from scan tool,
the troubleshooting can be performed more effi-
ciently. The displayed items are as the table below.
DISPLAY ITEM LIST

NOTE:

: If a failure occurs to both the ABS-ECU and

ETACS-ECU, 0000 mile or FFFF mile is displayed to

CAUTION

Do not replace the engine control module (ECM)
and WCM at the same time. When replacing sev-
eral ECUs, always replace one ECU at a time, reg-
ister the necessary IDs in it, and then replace the
next ECU.
The transponder (a small transmitter) in the ignition
key, WCM, and the ECM have their own ID codes
stored in them. When the cases listed in the table
below occur, the ID codes must be registered in the
WCM or ECM again.

NOTE: Up to eight ignition keys (key ID and keyless
entry secret code) can be stored in the memory of
WCM.

NOTE:

*

: Key (the key that can be used to lock/unlock the door or glove box only)

NOTE:
