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:
Door control transmitter
Registration
1. Registration of recognition code
Hint:
the add mode is used to retain the already registered codes while
registering a new recognition code.
This mode is used when adding a transmitter. If the number of the registered
codes exceeds 4, the
previously registered code wi ...
Source voltage drop
The srs is equipped with a voltage–increase circuit (dc–dc converter) in the
airbag sensor assy center
in case the source voltage drops.
When the battery voltage drops, the voltage–increase circuit (dc–dc converter)
functions to increase the
voltage of the srs to normal voltage.

Shift position uses
*: Shifting to the D position allows the system to select a gear suitable for
driving conditions. Setting the shift lever to the D position is recommended for
normal driving.
■Downshifting restrictions
The shift lever cannot be downshifted if the following speeds are exceeded.
