Terminals of ecuOpen in one side of can branch line
Description
If 2 or more ecus and/or sensors do not appear on the intelligent tester's
"bus check" screen via the
can vim, one side of the can branch wire may be open. (One side of the canh
[branch wire] /canl
[branch wire] of the ecu and/or sensor is open.)

Hydraulic test
Measure line pressure
Notice:
Perform the test at the normal operating atf
temperature: 50 to 80°c (122 to 176°f).
The line pressure test should always be
performed with at least 2 people. One person
should observe the condition of the wheels or
wheel chocks while the other ...
Vehicle speed sensor "A"
description
The speed sensor detects the wheel speed and sends the appropriate signals to
the skid control ecu.
The skid control ecu converts these wheel speed signals into a 4-pulse signal
and outputs it to the ecm
via the combination meter. The ecm determines the vehicle speed based o ...
