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)
