Toyota Corolla Repair Manual: 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 the hand–held tester.
1 Perform active test by hand–held tester(abs motor relay)
- Check the operation sound of the abs motor individually when operaing it
with the hand–held tester.
Ok: the operation sound of the abs motor should be heard.
2 Inspect skid control ecu connector(+bm terminal voltage)
- Disconnect the skid control ecu connector.
- measure the voltage between terminals +bm (24) and
gnd (1, 23) of skid control ecu harness side connector.
Voltage: 10 – 14 v
3 Inspect fuse(abs no.2 Fuse)
- Remove abs no.2 Fuse from the engine room r/b.
- check continuity of abs no.2 Fuse.
Ok: continuity
4 Inspect skid control ecu connector(gnd terminal continuity)
- Measure resistance between terminal gnd (1,23) of skid
control ecu harness side connector and body ground.
Resistance: 1 Ω or less
Check and replace brake actuator assy
Circuit description
The abs motor relay supplies power to the abs pump motor. While the abs is
activated, the ecu switches
the motor relay on and operates the abs pump motor.

Inspection procedure
1 Check security indicator light
Set the system in 30 seconds after filliping the security indicator to
check if the alarm is triggered.
2 Check glass breakage sensor ecu (glass breakage sensor)
Check the continuity and voltage of the glass breakage
sensor ecu, as shown in th ...
