C1279; YAW RATE SENSOR CIRCUIT FAULTG92304t10: CHECK THE POWER SUPPLY TO THE YAW RATE SENSOR
1. Turn the ignition switch to the OFF position.
2. Disconnect the yaw rate sensor electrical connector, IP20.
3. Turn the ignition switch to the ON position.
4. Measure the voltage between IP20, pin 04 (GW) and GROUND.
^ Is the voltage less than 5 volts?
> Yes
> No
G92304t15: CHECK THE YAW RATE SENSOR POWER SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the DSC control module electrical connector, JB185.
3. Measure the resistance between IP20, pin 04 (GW) and JB185, pin 39 (GW).
^ Is the resistance greater than 5 ohms?
> Yes REPAIR the high resistance circuit. This circuit includes harness splice, IPSO. CLEAR the DTC, test the system for normal operation.
> No REPAIR the circuit between the yaw rate sensor and battery. This circuit includes the primary distribution box (fuse 96), the ignition switch and the DSC control module. Please check part is not on any form of prior authorization before replacement.
G92304t11: CHECK THE GROUND TO THE YAW RATE SENSOR
1. Measure the resistance between IP20, pin 01 (B) and GROUND.
^ Is the resistance greater than 5 ohms?
> Yes
> No For CAN circuit tests,
G92304t16: CHECK THE YAW RATE SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the DSC control module electrical connector, JB185.
2. Measure the resistance between IP20, pin 01 (B) and JB185, pin 21 (B).
^ Is the resistance greater than 5 ohms?
> Yes REPAIR the high resistance circuit. This circuit includes harness splice, IPS7. Test the system for normal operation.
> No For CAN circuit tests, Please check part is not on any form of prior authorization before replacement.
