C1282

DTC C1282 YAW RATE & LATERAL G SENSOR-ELECTRICAL

COMPONENT LOCATION:

GENERAL DESCRIPTION
The yaw-rate & Lateral G sensor are used for the stability of a vehicle. The yaw-rate is used to measure angular velocity while the Lateral G is to measure the force that moves the vehicle away from the center, when a vehicle is cornering.

DTC DESCRIPTION
This code sets when there is an open or short in the circuit of the yaw-rate & lateral G sensor.

DTC DETECTING CONDITION

DTC DETECTING CONDITION:

TERMINAL & CONNECTOR INSPECTION
Refer to DTC C1101. C1101

POWER SUPPLY CIRCUIT INSPECTION
1. Ignition ON & Engine OFF.





2. Measure voltage between terminal 1 of the Yaw Rate & Lateral G sensor harness connector and chassis ground.
Specification: approximately B+
Is the measured voltage within specifications?
YES
- Go to Ground Circuit Inspection procedure.
NO
- Check for open or short to GND in the Yaw Rate & Lateral G sensor harness between terminal 3 of the Yaw Rate & Lateral G sensor harness connector and terminal "16,20 of the HECU harness connector. Repair as necessary and then go to Verification of vehicle Repair procedure.

GROUND CIRCUIT INSPECTION
1. Ignition "OFF".
2. Disconnect Yaw Rate & Lateral G sensor connector.





3. Measure resistance between terminal 4 of the Yaw Rate & Lateral G sensor harness connector and chassis ground.
Specification: Approximately below 1 Ohms
Is the measured resistance within specifications?
YES
- Go to Signal Circuit Inspection procedure.
NO
- Check for open or short in the Yaw Rate & Lateral G sensor harness between terminal 4 of the Yaw Rate & Lateral G sensor harness connector and terminal "15 of the HECU harness connector. Repair as necessary and then go to Verification of vehicle Repair procedure.

SIGNAL CIRCUIT INSPECTION
1. Ignition "ON".





2. Measure voltage between terminal 5, 6 of the Yaw Rate & Lateral G sensor harness connector and chassis ground.
Specification: Approximately 2.5 Volts
Is the measured voltage within specifications?
YES
- Go to Component Inspection procedure.
NO
- Check for open or short in the Yaw Rate & Lateral G sensor harness between terminal 5, 6 of the Yaw Rate & Lateral G sensor harness connector and terminal 1 6, 20 of the HECU harness connector. Repair as necessary and then go to Verification of Vehicle Repair procedure.

COMPONENT INSPECTION
1. Ignition "OFF".
2. Engine "ON".
Does warning lamp remain On?
YES
- Substitute with a known-good Yaw Rate & Lateral G sensor and check for proper operation. If problem is corrected, replace Yaw Rate & Lateral G sensor and then go to Verification of Vehicle Repair" procedure.
NO
- Fault is intermittent caused by open or short of Yaw Rate & Lateral G sensor harness and/or faulty Yaw Rate & Lateral G sensor or was repaired and HECU memory was not cleared. Go to the applicable troubleshooting procedure.

VERIFICATION OF VEHICLE REPAIR
Refer to DTC C1101. C1101
