Diagnostic Test

WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.

VERIFY THE DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE
1. Turn the ignition on.
2. With the scan tool, erase DTCs.
3. Turn the ignition off, wait 10 seconds, and turn the ignition on.
4. With the scan tool, actuate the Radiator Fan.
5. With the scan tool, read DTCs.
  Does the scan tool display active: B10BF-CONDENSER FAN CONTROL CIRCUIT HIGH?
  
  Yes
  - With the scan tool, de-actuate the Radiator Fan. Then, Go To 2
  No
  - With the scan tool, de-actuate the Radiator Fan. The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
CHECK (N112) HIGH SPEED RADIATOR FAN CONTROL CIRCUIT FOR A SHORT TO BATTERY VOLTAGE
1. Turn the ignition off
2. Disconnect the TIPM C11 harness connector.
3. Disconnect the Radiator Fan Motor harness connector.
4. Turn the ignition on.
5. Using a volt meter, measure the voltage on the (N112) High Speed Radiator Fan Control circuit at the Radiator Fan Motor harness connector.
  Does the volt meter read 10 volts, or above?
  
  Yes
  - Repair the (N112) High Speed Radiator Fan Control circuit for a short to battery voltage.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go to step 3
CHECK (Z823) GROUND CIRCUIT FOR AN OPEN
1. Turn the ignition off.
2. Reconnect the TIPM C8 harness connector.
  NOTE: The test light should illuminate brightly. Compare the brightness to that of a direct connection to the battery.
3. Using a 12-volt test light connected to 12 volts, probe the (Z823) Ground circuit at the Condenser Fan Motor harness connector.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 4
  No
  - Repair the excessive resistance in the (Z823) Ground circuit.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
CHECK RADIATOR FAN MOTOR
1. Ignition on, engine not running.
2. With the scan tool, actuate the Radiator Fan.
3. Using a 12-volt test light connected to ground, probe the (C123) Condenser Fan Control Output circuit at the Condenser Fan Motor harness connector.
  Does the test light illuminate brightly and flash on and off?
  
  Yes
  - With the scan tool, de-actuate the Condenser Fan. Then, replace the Condenser Fan Motor in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - With the scan tool, de-actuate the Condenser Fan. Then, Go To 5
INSPECT RELATED WIRING
NOTE: Before continuing, check the TIPM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.
1. Using the schematics as a guide, inspect the related wiring harness and connectors.
2. Pay particular attention to all Power and Ground circuits.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Replace the TIPM in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
