Diagnostic Test

CHECK FOR ACTIVE DTC
NOTE: If B2104 or B2105 are active, perform those tests first before proceeding.

NOTE: Check the Junction Block Fuse #24. An open fuse can cause this DTC to set. If open refer to the wiring diagrams to help isolate a possible shorted circuit.
1. With the scan tool, read the active DTCs.
2. Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 10 seconds.
3. With the scan tool, read the active DTCs.
  Does the scan tool display this DTC as active?
  
  Yes
  - Go to step 2
  No
  - If the DTC is stored, check for an intermittent condition. Using the wiring diagram/schematic as a guide, visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .

1. Turn the ignition off.
2. Disconnect the IPM C2 connector.
3. Turn the ignition on.
4. Measure the voltage of the (F942) Fused Ignition Switch Output circuit in the IPM C2 connector.
  Is the voltage above 10.0 volts?
  
  Yes
  - Go to step 3
  No
  - Repair the (F942) Fused Ignition Switch Output circuit for an open.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure .
