Diagnostic Test

A/C CLUTCH OPERATION
1. Ignition on, engine not running.
2. With a scan tool in the TIPM Actuators, actuate the A/C Clutch.
  Is the A/C Clutch operating?
  
  Yes
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 2
VISUAL AND PHYSICAL CONNECTOR AND TERMINAL INSPECTION
1. Turn the ignition off.
2. Disconnect the TIPM C10 harness connector.
3. Disconnect the A/C Clutch harness connector.
4. Inspect the terminal and connector condition. Check for signs of corrosion build up or damage the would compromise the terminal to controller pin connector.
  NOTE: Make sure that all in-line connectors are inspected for corrosion and/or damage.
5. Visually inspect the wiring harness. Look for any chafed, pierced, pinched or partially broken wires hidden in the wire insulation.
  Were any of the above conditions found?
  
  Yes
  - Repair or replace as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 3

1. With a jumper wire, connect one end to the (C3) A/C Clutch Control Output circuit in the A/C Clutch harness connector and the other to a clean chassis ground.
2. Using a 12-volt test light to battery voltage, probe the (C3) A/C Clutch Control Output circuit in the TIPM C10 harness connector.
  NOTE: The test light should be illuminated and bright. Compared the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly.
  
  Yes
  - Go to step 4
  No
  - Repair the high resistance 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 .
(Z902) A/C CLUTCH GROUND CIRCUIT

1. Using a 12-volt test light to battery voltage, probe the (Z902) A/C Clutch Ground circuit in the A/C Clutch harness connector.
  NOTE: The test light should be illuminated and bright. Compared the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly.
  
  Yes
  - Go to step 5
  No
  - Repair the excessive resistance in the (Z902) A/C Clutch Ground circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
A/C CLUTCH CONTROL OUTPUT FROM TIPM
1. Reconnect the TIPM C10 harness connector.
2. Ignition on, engine not running.
3. With a scan tool in the TIPM Actuators, actuate the A/C Clutch.
4. Using the 12-volt test light connected to ground, probe the (C3) A/C Clutch Control Output circuit in the A/C Clutch harness connector.
  Does the test light illuminate brightly?
  
  Yes
  - Replace the A/C Clutch.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Replace the Totally Integrated Power Module (TIPM) in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
