Toyota Corolla Cross: Terminals Of Ecm
TERMINALS OF ECM
HINT:
The standard normal voltage and resistance between each pair of ECM terminals
is shown in the table below. The appropriate conditions for checking each pair of
terminals are also indicated. The result of checks should be compared with the standard
normal voltage and resistance for that pair of terminals, displayed in the Specified
Condition column. The illustration above can be used as a reference to identify
the ECM terminal locations.

DESCRIPTION
The airbag ECU assembly has a built-in yaw rate and acceleration
sensor and detects the vehicle condition.
The skid control ECU (brake actuator assembly) memorizes the
range of the acceleration sensor (airbag ECU assembly) and the range of vehicle
speed calculated using each spee
