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.

Front (vehicles with slide function)
Slide the console box lid forward
or backward as needed.
Pull the lid forward by holding
the front of the lid.
Rear
Fold down the armrest for use.
Notice
To prevent damage to the armrest
Do not apply too much load on the armrest. ...
Removal
Hint:
Use the same procedures for the rh side and lh side.
The procedures listed below are for the lh side.
Disconnect cable from negative battery

Diagnosis system
Check dlc3
Check the dlc3:
the power steering ecu uses can (iso11898-1)
and iso9141-2 for communication protocol. The
terminal arrangement of the dlc3 complies with
sae j1962 and matches the iso9141-2 format.
Notice:
*: Before measuring the resistance, leave the
vehicle ...
