DTC C1283 YAW RATE AND LATERAL G SENSOR-SIGNALCOMPONENT LOCATION
Refer to DTC C1282. C1282
GENERAL DESCRIPTION
Refer to DTC C1282. C1282
DTC DESCRIPTION
A lateral acceleration reference signal is calculated from the wheel speeds, the steering angle and the yaw rate signals to observe the lateral acceleration sensor signal. The difference between the reference signal and the sensor signal is evaluated for failure detection. A yaw rate reference signal is calculated from the wheel speeds, the steering angle and the lateral acceleration signals to observe the yaw rate sensor signal. The difference between the reference signal and the sensor signal, and the gradient of the measured sensor signal is evaluated for the failure detection. If the difference between estimated value and measured value of the sensor is larger than predefined value for predefined time, the failure is recognized. Also if an impossible signal according to sensor characteristic is detected the failure is recognized.
DTC DETECTING CONDITION:
MONITOR SCANTOOL DATA
Refer to DTC C 1282.
TERMINAL & CONNECTOR INSPECTION
Refer to DTC C1102. C1102
SIGNAL CIRCUIT INSPECTION
1. Ignition "ON" & Engine "OFF".
2. Measure voltage between terminal "3, 5, 6" of the Yaw Rate & Lateral G sensor harness connector and chassis ground.
3. Is the measured resistance within specifications?
YES
^ Go to "Self Test Circuit Inspection" procedure.
NO
^ Check for open or short in the Yaw Rate & Lateral G sensor harness between terminal "3, 5, 6" of the Yaw Rate & Lateral G sensor harness connector and terminal "16, 18, 20" of the chassis ground. Repair as necessary and then go to "Verification of vehicle Repair" procedure.
^ If OK, Substitute with a known-good Yaw Rate & Lateral G sensor and check for proper operation. If problem is corrected, replace sensor and then go to "Verification of Vehicle Repair" procedure.
