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.

CAUTION

• During troubleshooting, a DTC code associated with other system may be set when the ignition

switch is turned on with connector(s) disconnected. On completion, check all systems for DTC
code(s). If DTC code(s) are set, erase them all.

• When the combination meter is required to be replaced as a result of the troubleshooting, the cur-

rent driving distance and number of elapsed days to be used for service reminder function must
be entered into the meter after the replacement. Therefore, read "Integrated mileage for reminder,"
"Integrated days for reminder," "Mileage until Extra reminder," "Months until Extra reminder," and
"Current Schedule" from the meter before the replacement using the special function of scan tool
MB991958, and note them. For the operation method of scan tool MB991958, refer to

P.54A-93

. If

"Integrated mileage for reminder" or "Integrated days for reminder" cannot be read by the scan
tool MB991958, follow the method described below.

a. For the driving distance for check warning, use the driving distance displayed on the multi

information display.

b. For the elapsed days for check warning, calculate the number of elapsed days from the deliv-

ery date to the customer (service remainder function start date) and current date.
