Toyota Corolla (E120): Inspection procedure
Hint
: start the inspection from step 1 in case of using the hand–held tester and start from step 2 in case of not using hand–held tester.
1 Inspect brake actuator assy
- Select the datalist mode on the hand–held tester.
- check the operation sound of the abs pump motor when operating it
with the hand–held tester.
Ok: the operation sound of the abs pump motor should be heard.
2 Inspect skid control ecu terminal voltage(+bm terminal voltage)
- Disconnect the skid control ecu connector.
- measure the voltage between terminal +bm (24) and
gnd (23) of skid control ecu harness side connector.
Ok: the operation sound of the abs pump motor should be heard.
Replace brake actuator assy

Circuit description
The vehicle speed sensor circuit is sent to cruise control ecu assy as a
vehicle speed signal. For each rotation
of the shaft, the vehicle speed sensor sends a signal through the combination
meter assembly to the
cruise control ecu assy (see the following chart). The cruise control ecu assy
...
