G307559t8: CHECK THE WSS TO ABS/DSC MODULE SIGNAL CIRCUIT FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the ABS/DSC module electrical connector EC30.
3. Disconnect the WSS electrical connector EC15.
4. Measure the resistance between EC30, pin 34 (WU) and EC15, pin 02 (WU).
^ Is the resistance greater than 5 ohms?
-> Yes REPAIR the high resistance circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.
-> No GO to Pinpoint Test G307559t9.
G307559t9: CHECK THE WSS TO ABS/DSC MODULE SIGNAL CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between EC30, pin 34 (WU) and GROUND.
^ Is the resistance less than 10,000 ohms?
-> Yes REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.
-> No GO to Pinpoint Test G307559t10.
G307559t10: CHECK THE WSS TO ABS/DSC MODULE SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Measure the resistance between EC30, pin 33 (NG) and EC15, pin 01 (NG).
^ Is the resistance greater than 5 ohms?
-> Yes REPAIR the high resistance circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.
-> No GO to Pinpoint Test G307559t2.
G307559t2: CHECK THE WSS TO ABS/DSC MODULE SUPPLY CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between EC30, pin 33 (NG) and GROUND.
^ Is the resistance less than 10,000 ohms?
-> Yes REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.
-> No INSTALL a new right-hand front wheel speed sensor.
CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, contact dealer technical support for advice on possible ABS/DSC module failure.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
