BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS ELECTRONICALLY CONTROLLED BRAKE SYSTEM(for Gasoline Model) C14D71C Multi-axis Acceleration Sensor Module "A" Supply Voltage Circuit Voltage Out of Range

DESCRIPTION

The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.

This DTC is stored when the skid control ECU (brake actuator assembly) receives a sensor supply voltage malfunction signal from the yaw rate and acceleration sensor (airbag sensor assembly).

PROCEDURE

1.CHECK HARNESS AND CONNECTOR (POWER SOURCE TERMINAL)

Pre-procedure1

Turn the ignition switch off.

Disconnect the cable from the negative (-) battery terminal.

CAUTION:: Wait at least 60 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.; Click hereVehicle Interior>SUPPLEMENTAL RESTRAINT SYSTEMS>AIRBAG SYSTEM>PRECAUTION202111,202203,_58,_111838,_0499714,RM100000001YZDL,202203,202303,_58,_111838,_0499714,RM1000000022EO1,202303,999999,_58,_111838,_0499714,RM100000002AQNJ,

Procedure1

Make sure that there is no looseness at the locking part and the connecting part of the connector.

OK:: The connector is securely connected.

Pre-procedure2

Disconnect the E64 yaw rate and acceleration sensor (airbag sensor assembly) connector.

Procedure2

Check both the connector case and the terminals for deformation and corrosion.
