Toyota Corolla Repair Manual: Dtc check/clear
Notice
:
- if there is no dtc in the normal mode, check the pending
fault code using the continuous test results
function (mode 7 for sae j1979) on the obd ii scan
tool or the hand–held tester.
- Hand–held tester only:
when the diagnosis system is switched from the normal
mode to the check mode, all the dtcs and freeze
frame data recorded in the normal mode will be
erased. So before switching modes, always check the
dtcs and freeze frame data, and then write them
down.
1. Check dtc (using the obd ii scan tool or hand–held tester)

- Connect the obd ii scan tool or hand–held tester to the
dlc3.
- turn the ignition switch on.
- use the obd ii scan tool or the hand–held tester to check
the dtcs and freeze frame data and then write them
down. If you need help with the obd ii scan tool, refer to
the scan tool’s instruction book.
If there is no dtc in the normal mode, check the pending
fault code using the continuous test results function on
the obd ii scan tool or the hand–held tester.
- to confirm the details of the dtcs.
Notice
:
- when simulating a symptom with the obd ii scan tool
(excluding hand–held tester) to check the dtcs, use
the normal mode. For code on the dtc chart subject
to the ”2 trip detection logic”, perform either of the following
actions.
- Turn the ignition switch off after the symptom is
simulated once. Then repeat the simulation process
again. When the problem has been simulated twice,
the mil lights up and the dtcs are recorded in the
ecm.
- Check the pending fault code using the continuous
test results function on the obd ii scan tool.
2. Clear dtc (using the obd ii scan tool or hand–held
tester)
- Connect the obd ii scan tool or the hand–held tester to
the dlc3.
- turn the ignition switch on.Operate the obd ii scan tool or the
hand–held tester to
erase the codes. All the dtcs and freeze frame data will
be erased. (See the obd ii scan tool’s instruction book for
operating instructions.)
3. Clear dtc (not using the obd ii scan tool or hand–
held tester)
- Disconnect the battery terminal or remove the efi fuse
from the engine room r/b for more than 60 seconds.
The vehicle’s ecm uses the iso 9141–2 for communication
protocol. The terminal arrangement of the dlc3 complies
with sae j1962 and matches the iso 9141–2 format.
