Diagnostic Test

RADIATOR FAN CONTROL RELAY OPERATION
NOTE: When actuating the radiator fan relays, the Radiator Fan(s) may have a delay in operation and ramp up slowly.
1. Turn the ignition on.
2. With a scan tool, select Radiator Cooling Fan Relay #1 Control State to actuate the Radiator Fan Control Relay.
  Is the Cooling Fan Relay operating?
  
  Yes
  - Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  - Perform the PCM Verification Test. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  No
  - Go to step 2

1. Turn the ignition off.
2. Remove the Radiator Fan Control Relay.
3. Using a 12 volt test light connected to ground, check the Fused B+ circuits.
  Is the test light illuminated and bright?
  
  Yes
  - Go to step 3
  No
  - Repair the open or short to ground in the Fused B+ circuits. Inspect the related fuse and repair as necessary.
  - Perform BODY VERIFICATION TEST - VER 1. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure

1. Turn the ignition on, engine not running.
2. With a scan tool, actuate the Radiator Cooling Fan Relay #1 Control State.
3. Using a 12-volt test light connected to battery voltage, check the Radiator Control Relay Control circuit.
  Does the test light illuminate with the actuation?
  
  Yes
  - Replace the Radiator Fan Control Relay.
  - Perform BODY VERIFICATION TEST - VER 1. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure
  No
  - Go to step 4
(N201) RADIATOR FAN CONTROL RELAY CONTROL CIRCUIT OPEN

1. Turn the ignition off.
2. Remove the FCM from the PDM.
3. Measure the resistance of the (N201) Radiator Fan Control Relay Control circuit from the Relay to the FCM PDM - 49 way connector.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Go to step 5
  No
  - Replace the PDM in accordance with the Service information.
  - Perform BODY VERIFICATION TEST - VER 1. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure
(N201) RADIATOR FAN CONTROL RELAY CONTROL CIRCUIT SHORTED TO GROUND

1. Measure the resistance between ground and the (N201) Radiator Fan Control Relay Control circuit at the Relay connection.
  Is the resistance below 100 ohms?
  
  Yes
  - Replace the PDM in accordance with the Service information.
  - Perform BODY VERIFICATION TEST - VER 1. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure
  No
  - Replace Front Control Module in accordance with the Service Information.
  - Perform BODY VERIFICATION TEST - VER 1. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure
