Description
When there is an abnormality in the power supply circuit of the brake actuator (skid control ecu), the skid control ecu sets a dtc and the operation is prohibited by the fail-safe function. This dtc is set when the voltage supplied to terminal ig1 is outside the dtc detection threshold, due to abnormalities of the battery, power source circuits or charging circuits such as the alternator circuit.
The fail-safe function is canceled when the voltage to terminal ig1 returns to normal.

Work in a location with good air ventilation that
does not have welders, grinders, drills, electric
motors, stoves, or any other ignition sources.
Never work in a pit or near a pit as vaporized
fuel will collect in those places.

Check mode procedure
Hint:
Intelligent tester only:
compared to normal mode, check mode is more sensitive to
malfunctions. Therefore, check mode can detect the
malfunctions that cannot be detected by normal mode.
Notice:
All the stored dtcs and freeze frame data are erased if:
The ecm is changed from normal mo ...
