WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

CHECK FOR DTC C1018-RIGHT FRONT WHEEL SPEED SENSOR CIRCUIT HIGH
NOTE: This DTC must be active for the results of this test to be valid.
1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Cycle the ignition switch from off to on.
4. With the scan tool, read DTCs.
  Does the scan tool display: C1018-RIGHT FRONT WHEEL SPEED SENSOR CIRCUIT HIGH?
  
  Yes
  - Go to step 2
  No
  - Perform the ABS-INTERMITTENT CONDITION TEST. Refer to DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
CHECK CONNECTOR/TERMINAL FOR DAMAGE
NOTE: Check all terminals for broken, bent, pushed out, or corroded terminals.
1. Turn the ignition off.
2. Inspect the Anti-Lock Brake Module harness connector, Right Front WSS, and Right Front WSS harness connector.
  Is the Right Front WSS or any of the connectors/terminals damaged?
  
  Yes
  - Repair as necessary.
  - Perform the ABS VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure .
  No
  - Go to step 3
