Diagnostic Test

CHECK FOR AN ACTIVE DTC
NOTE: Before proceeding with this diagnostic procedure, verify the Left and Right Multifunction Switch and Clockspring harness connectors are properly seated and verify proper pin terminal tension. A loose connection at any of these connectors may cause this DTC to set.
1. Turn the ignition on.
2. With the scan tool, read DTCs.
  Does the scan tool display this DTC as active?
  
  Yes
  - Go to step 2
  No
  - Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.

1. Turn the ignition off.
2. Disconnect the Right Steering Wheel Switch harness connector.
3. Turn the ignition on.
4. Measure the voltage of the (A108) Fused B (+) circuit.
  Is the voltage above 10.0 volts?
  
  Yes
  - Go to step 3
  No
  - Using the Wiring Information as a guide, repair the (A108) Fused B (+) circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .

1. Turn the ignition off.
2. Measure the resistance between ground and the (Z907) Ground circuit at the Right Steering Wheel Switch harness connector.
  Is the resistance below 10K Ohms?
  
  Yes
  - Go to step 4
  No
  - Using the Wiring Information as a guide, repair the (Z907) Ground circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
