Diagnostic Test

VERIFY DTC B106B-REAR DEFROST CONTROL CIRCUIT LOW IS ACTIVE
1. Ensure the Rear Defogger is switched off.
2. With the scan tool, erase TIPM DTCs.
3. Operate the Rear Defogger Switch several times.
4. With the scan tool, read TIPM DTCs.
  Does the scan tool display active DTC B106B-REAR DEFROST CONTROL CIRCUIT LOW?
  
  Yes
  - Go to step 2
  No
  - Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, corroded, or contaminated terminals.
  - Perform BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
INSPECT (C515) REAR WINDOW DEFOGGER CONTROL OUTPUT CIRCUIT AT REAR WINDOW GRID
1. Inspect (C515) Rear Window Defogger Control Output wiring at rear window grid. If necessary remove trim around rear window.
2. Check for a chafed, pierced or pinched wire. Also look for a metal object that may cause a short to ground condition at the grid.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go to step 3
