DTC C1232/32 - Stuck in Acceleration Sensor

DTC C0371/71 - Yaw Rate Sensor (Test Mode DTC)

DTC C1234/34 - Yaw Rate Sensor Malfunction

DTC C1243/43 - Acceleration Sensor Stuck Malfunction

DTC C1244/44 - Open or Short in Acceleration Sensor Circuit

DTC C1245/45 - Acceleration Sensor Output Malfunction

DTC C1279/79 - Acceleration Sensor Output Voltage Malfunction (Test Mode DTC)

DTC C1381/97 - Acceleration Sensor Power Supply Voltage Malfunction

DESCRIPTION

The yaw rate and acceleration sensor send signals to the skid control ECU through the CAN communication system. When there is a malfunction in the communication, it will be detected by the diagnosis function.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK SENSOR
(a) Check that the yaw rate and acceleration sensor has been installed properly .
OK:
The sensor should be tightened to the specified torque.
The sensor should not be tilted.
NG -- INSTALL YAW RATE AND ACCELERATION SENSOR PROPERLY
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR
(a) Disconnect the yaw rate and acceleration sensor connector.
(b) Turn the ignition switch to the ON position.





(c) Measure the voltage according to the value(s) in the table below.
Standard voltage:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR
(a) Disconnect the yaw rate and acceleration sensor connector.





(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE YAW RATE AND ACCELERATION SENSOR
