Toyota Corolla (E120): Fail–safe chart
If any of the following codes is recorded, the ecm enters the fail–safe mode.
Check for intermittent problems
Hand–held tester only:
by putting the vehicle’s ecm in the check mode, the 1 trip detection logic is possible instead of the 2 trip detection logic, and the sensitivity to detect faults is increased. This makes it easier to detect intermittent problems.
- Clear the dtcs .
- set the check mode .
- perform a simulation test .
- check the connector and terminal .
- wiggle the harness and connector
Other materials:
Inspection
1. Inspect inner rear view mirror assy
Inspect the electro chromic inner mirror operation.
Connect the positive (+) lead from the battery to terminal
1 and negative (–) lead to terminal 2.
) Attach black colored tape to the forward sensor to
prevent it from sensing.

record dtcs and the freeze frame data.
set the check mode using the hand–held tester .

Circuit description
While driving uphill with cruise control activated, in order to minimize gear
shifting and provide smooth cruising
overdrive may be prohibited temporarily under some conditions.
The cruise control ecu sends o/d cut signals to the ecm as necessary and the ecm
cancels overdrive
