BRC-48 < DTC/CIRCUIT DIAGNOSIS > [TYPE 1] C1113, C1145, C1146 YAW RATE/SIDE/DECEL G SENSOR C1113, C1145, C1146 YAW RATE/SIDE/DECEL G SENSOR Description INFOID:0000000009479276 The yaw rate/side/decel G sensor detects the yaw rate/side/decel G affecting the vehicle, and transmits the data to the ABS actuator and electric unit (control unit) as an analog voltage signal. DTC Logic INFOID:0000000009479277 DTC DETECTION LOGIC DTC CONFIRMATION PROCEDURE 1. CHECK SELF-DIAGNOSIS RESULTS Check the self-diagnosis results. Is above displayed on the self-diagnosis display? YES >> Proceed to diagnosis procedure. Refer to . NO >> Inspection End Diagnosis Procedure INFOID:0000000009479278 Regarding Wiring Diagram information, refer to BRC-92, "Wiring Diagram - VDC WITHOUT HILL DESCENT CAUTION: • Sudden turns (such as spin turns, acceleration turns), drifting, etc. when VDC function is OFF may cause the yaw rate/side/decel G sensor system to indicate a malfunction. This is not a malfunction if normal operation can be resumed after restarting the engine. • If vehicle is on turn table at entrance to parking garage, or on other moving surface, VDC OFF indica- tor lamp may illuminate and CONSULT self-diagnosis may indicate yaw rate sensor system malfunc- tion. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of turn table or other moving surface, and start engine. Results will return to normal. 1. CONNECTOR INSPECTION 1. Disconnect the ABS actuator and electric unit (control unit) connector and yaw rate/side/decel G sensor connector. 2. Check the terminals for deformation, disconnection, looseness or damage. YES >> GO TO 2 NO >> Repair or replace as necessary. 2.
