VERIFY DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE
NOTE:
If present, diagnose and repair DTC C2114-DYNAMICS SENSOR SUPPLY VOLTAGE LOW or DTC C2115-DYNAMICS SENSOR SUPPLY VOLTAGE HIGH before proceeding.
1. Turn the ignition on.
2. Using the scan tool, read and record ABS DTC's.
3. Using the scan tool, read and record Environmental Data (EV Data).
4. Using the scan tool, erase ABS DTC's.
5. Cycle the ignition switch.
6. Using the scan tool, read ABS DTC's.
  Does this DTC reset?
  
  Yes
  - Go To 2.
  No
  - Perform the ABS INTERMITTENT CONDITION diagnostic procedure. Refer to ABS INTERMITTENT CONDITION .
INSPECT RELATED WIRING HARNESS, TERMINALS, AND CONNECTORS
WARNING:
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

NOTE:
Proper Steering Angle Sensor installation is crucial for proper operation.
1. Visually inspect the related wiring harness. Look for any pinched, chafed, pierced, and partially broken wires.
2. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, and corroded terminals.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST .
  No
