Diagnostic Test

INTERMITTENT DTC
1. Using the scan tool, erase the current WIN DTCs.
2. Turn the ignition off.
3. Arm the Vehicle Theft and Security System (VTSS) and wait one minute.
4. Disarm the VTSS and turn the ignition on.
  Does the scan tool display the same DTC?
  
  Yes
  - Go To step 2
  No
  - The condition that caused this symptom is currently not present. Inspect the related wiring harness for a possible intermittent condition. Look for any chafed, pierced, pinched or partially broken wires.
  - Perform the WIN VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure
