  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go to step 2
CHECK FOR ACTIVE DIAGNOSTIC TROUBLE CODE (DTC)
1. With the scan tool, read the active DTCs.
2. Erase the DTCs.
3. Turn the ignition off, wait 10 seconds, then turn the ignition on.
4. With the scan tool, read the active DTCs.
  Does the scan tool display this DTC as active?
  
  Yes
  - Go to step 3
  No
  - If the DTC is stored, check for an intermittent condition. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals, and repair any obvious problems.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
