Toyota Corolla (E120): Inspection procedure
1 Reconfirm dtc
- Check the dtc
2 Inspect skid control ecu connector securely connected
3 Inspect skid control ecu connector(ig1 terminal voltage)
In case of using hand–held tester:
- check the voltage condition output from the ecu displayed on the
hand–held tester.
Ok: ”normal” is displayed.
In case of not using hand–held tester:
- disconnect the skid control ecu connector.
- turn the ignition switch to on.
- measure voltage between terminals ig1 (3) and gnd (1,
23) of skid control ecu harness side connector.
Ok: oltage: 10 – 14 v
4 Inspect skid control ecu connector(gnd terminal continuity)
- Measure resistance between terminal gnd (s1–2, 24) of
skid control ecu harness side connector and body
ground.
Resistance: 1 Ω or less
Check and repair harness and connector
5 Go to combination meter system(abs warning light)
- Disconnect the skid control ecu connector.
- using service wire, connect terminals wa (30) and gnd (1, 23) of skid control ecu harness side connector.
- turn the ignition switch to on.
Ok: abs warning light goes off.

Inspection procedure
Hint:
hand–held tester only:
narrowing down the trouble area is possible by performing ”a/f control” active
test (heated oxygen
sensor or other trouble areas can be distinguished).
Perform active test using hand–held tester (a/f control).
Hint:
”a/f control” is the active te ...
Overhaul
1. Precaution
2. Disconnect battery negative terminal
3. Inspect place front wheels facing straight ahead
4. Remove horn button assy
Notice:
if the airbag connector is disconnected with the ignition
switch being at on, dtcs will be recorded.
using a torx socket wrench, loosen the ...
