1. Turn the ignition off.
2. Disconnect the C2 TIPM harness connector.
3. Disconnect the A/C Compressor Clutch harness connector.
4. Ignition on, engine not running.
5. Measure the voltage on the (C3) A/C Clutch Control Output circuit at the A/C Compressor Clutch harness connector.
  Is there any voltage present?
  
  Yes
  - Repair the short to battery voltage in the (C3) A/C Clutch Control Output circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .

1. Turn the ignition off.
2. Connect the C2 TIPM harness connectors.
3. Using a 12-volt test light connected to 12-volts, probe the (Z153) A/C Clutch ground circuit at the A/C Compressor Clutch harness connector.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 4
  No
  - Repair the excessive resistance in the (Z153) A/C Clutch ground circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .

1. Ignition on, engine not running.
2. With a 12-volt test light connected to ground, probe the (C3) A/C Clutch Control Output circuit at the A/C Compressor Clutch harness connector.
3. Using the scan tool under the TIPM Actuators, actuate the A/C Clutch.
  Does the test light illuminate brightly and flash on and off?
  
  Yes
  - Replace the A/C Compressor Clutch per Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Inspect the A/C Clutch Control Output circuit for an open.
    If OK, replace the Totally Integrated Power Module per Service Information.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
