INSPECTION PROCEDURE
HINT:
Read freeze frame data using   
 . Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running
or stopped, the engine was warmed up or not, etc. at the time of the malfunction.

INSPECTION PROCEDURE
HINT:
Start the inspection from step 1 if you are using the hand±held tester and start from step 2 if you are not using
the hand±held tester.
1 READ VALUE OF HAND±HELD TESTER(FRONT SPEED SENSOR)
(a) Select the item ºWHEEL SPEED FL (FR)º in the DATA LIST and read the value displayed on the hand±
held tester.
(b) Check that there is no difference between the speed value output from the speed sensor displayed
on the hand±held tester and the speed value displayed on the speedometer when driving the vehicle.
OK:
There is almost no difference in the displayed speed value.
HINT:
There is tolerance of
10 % in the speedometer indication.
OK Go to step 5
