MONITOR DESCRIPTION
C148B (Case 1):When the electronically controlled brake system is operating or shutting down and the voltage value of the No. 1 temperature sensor exceeds a certain value, the electric brake booster (brake booster with master cylinder assembly) illuminates the MIL and stores this DTC.
When the electronically controlled brake system is operating or shutting down and the voltage value of the No. 1 temperature sensor is less than a certain value, the electric brake booster (brake booster with master cylinder assembly) illuminates the MIL and stores this DTC.
When the electronically controlled brake system is operating or shutting down and it is detected that the total voltage value of the No. 1 and No. 2 temperature sensor is outside of a certain range a certain number of times or more, the electric brake booster (brake booster with master cylinder assembly) illuminates the MIL and stores this DTC.
When the electronically controlled brake system is operating or shutting down and the voltage value of the No. 2 temperature sensor exceeds a certain value, the electric brake booster (brake booster with master cylinder assembly) illuminates the MIL and stores this DTC.
When the electronically controlled brake system is operating or shutting down and the voltage value of the No. 2 temperature sensor is less than a certain value, the electric brake booster (brake booster with master cylinder assembly) illuminates the MIL and stores this DTC.
