Toyota Corolla (E120): Manual shifting test
1. Perform manual shifting test
Hint
: by this test, it can be determined whether the trouble is within the electrical circuit or is a mechanical problem in the transaxle.

- Disconnect the transmission wire connector.
- inspect the manual driving operation.
Check that the shift and gear positions correspond to the table below.
While driving, shift through the l, 2 and d positions.
Check that the gear change corresponds to the shift position.

Hint
: if the gear positions of the l, 2 and d are difficult to distinguish, do the following road test.
If any abnormality is found in the above test, the problem is in the transaxle itself.
- Connect the transmission wire connector.
- clear the dtc

Inspection procedure
1 Check fuse(ecu–ig)
Remove the ecu–ig fuse from the instrument panel j/b.
check the continuity of the ecu–ig fuse.
Ok: continuity
2 Inspect terminal voltage(b)
Remove the cruise control ecu assy with connector still
connected.
turn the ignition switch ...
Circuit description
When the brake pedal is depressed, the stop lamp switch assy sends a signal
to the cruise control ecu assy.
When the cruise control ecu assy receives this signal, it cancels the cruise
control.
A fail–safe function is provided so that cancel functions normally, even if
there is a malfu ...
Dtc check/clear
1. Dtc check (normal mode)
Notice:
hand–held tester only:
when the diagnostic 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 ...
