RADIATOR COOLING FAN MODULE OPERATION
1. Ignition on, engine not running.
2. With a scan tool, select Radiator Cooling Fan Relay #1 Control State to actuate the Cooling Fan (Low/High).
  Is the one Cooling Fan operating?
  
  Yes
  - Refer to the CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 2

1. Ignition on.
2. Disconnect the Low/High Rad Relay harness connector.
3. Using a 12-volt test light connected to ground, probe the (A16) Fused B+ circuit in the Low/High Rad Relay harness connector.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 3
  No
  - Repair the (A16) Fused B+ circuit. Inspect the related fuse and repair as necessary.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .

1. Turn the ignition on, engine not running.
2. With a scan tool, select Radiator Cooling Fan Relay #1 Control State, Toggle, to actuate the Cooling Fan (Low/High).
3. Using a 12-volt test light connected to battery voltage, probe the (N201) Low/High Rad Fan Control circuit in the Low/High Rad Relay harness connector.
  Does the test light illuminate brightly and flash on and off?
  
  Yes
  - Replace the Low/High Rad Fan Relay.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go to step 4
(N201) LOW/HIGH RAD FAN CONTROL CIRCUIT SHORTED TO BATTERY VOLTAGE

1. Disconnect the TIPM C11 harness connector.
2. Using a voltmeter, measure the voltage of the (N201) Low/High Rad Fan Control circuit in the Low/High Rad Relay harness connector.
  Is there voltage present?
  
  Yes
  - Repair the short to voltage in the (N201) Low/High Rad Fan Control circuit
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go to step 5
(N201) LOW/HIGH RAD FAN CONTROL CIRCUIT OPEN

1. Measure the resistance of the (N201) Low/High Rad Fan Control circuit from the Low/High Rad Relay harness connector to the TIPM C11 harness connector.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Go to step 6
  No
  - Repair the open in the (N201) Low/High Rad Fan Control circuit.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
(N201) LOW/HIGH RAD FAN CONTROL CIRCUIT SHORTED TO GROUND

1. Measure the resistance between ground and the (N201) Low/High Rad Fan Control circuit in the TIPM C11 harness connector.
  Is the resistance below 100 ohms?
  
  Yes
  - Repair the short to ground in the (N201) Low/High Rad Fan Control circuit.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Replace the Totally Integrated Power Module in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
