PINPOINT TEST G307559p7: C1279, C1281, C2778, C2785, B2741; LATERAL/YAW RATE CIRCUIT FAILURE
G307559t28: CHECK THE VOLTAGE SUPPLY TO THE LATERAL/YAW RATE SENSOR
1. Disconnect the yaw/lateral rate sensor electrical connector IP23.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between IP23, pin 03 (r) and GROUND.
^ Is the voltage less than 10 volts?
Yes: GO to Pinpoint Test G307559t29.
No: GO to Pinpoint Test G307559t4.

G307559t29: CHECK THE YAW/LATERAL RATE SENSOR VOLTAGE SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the ABS/DSC module electrical connector EC30.
3. Measure the resistance between IP23, pin 03 (r) and EC30, pin 07 (r).
^ Is the resistance greater than 5 ohms?
Yes: REPAIR the high resistance circuit. This circuit includes the splice IPS1 4. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
No: GO to Pinpoint Test G307559t30.

G307559t30: CHECK THE YAW/LATERAL RATE SENSOR VOLTAGE SUPPLY CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between IP23, pin 03 (r) and GROUND.
^ Is the resistance less than 10,000 ohms?
Yes: REPAIR the short circuit. This circuit includes the splice IPS1 4. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
No: Contact dealer technical support for advice on possible ABS/DSC module failure.

G307559t4: CHECK THE GROUND TO THE YAW/LATERAL RATE SENSOR
1. Measure the resistance between IP23, pin 05 (13K) and GROUND.
^ Is the resistance greater than 5 ohms?
Yes: GO to Pinpoint Test G307559t67.
No: GO to Pinpoint Test G307559t32.

G307559t67: CHECK THE YAW/LATERAL RATE SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the ABS/DSC module electrical connector EC30.
3. Measure the resistance between IP23, pin 05 (13K) and EC30, pin 05 (13K).
^ Is the resistance greater than 5 ohms?
Yes: REPAIR the high resistance circuit. This circuit includes the splice IPS1 0. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
No: GO to Pinpoint Test G307559t32.

G307559t32: CHECK THE YAW/LATERAL RATE SENSOR GROUND CIRCUIT FOR SHORT TO B+
1. Measure the voltage between IP23, pin 05 (13K) and GROUND.
^ Is the voltage greater than 3 volts?
Yes: REPAIR the short circuit. This circuit includes the splice IPS1 0. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
No: Contact dealer technical support for advice on possible ABS/DSC module failure.
