Diagnostic Test

CHECK IF THE DTC IS ACTIVE
1. Ignition on, engine not running.
2. With the scan tool, select View DTCs.
  Is the status Active for this DTC?
  
  Yes
  - Go To 2
  No
  - Go To 5

1. Turn the ignition off
2. Disconnect the TIPM C10 harness connector.
3. Disconnect the PCM C4 harness connector.
4. Measure the resistance between the (T16) Transmission Control Output at the at the TIPM C10 harness connector and ground.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T16) Transmission Control Output for a short to ground.
  - Perform the 40/41TE VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go To 3
CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Reconnect the TIPM C10 harness connector.
3. Disconnect the Transmission Solenoid harness connector.
4. Ignition on, engine not running.
5. Using the scan tool under the TIPM Actuators, actuate the Transmission control output.
6. Using a 12-volt test light connected to ground, check the (T16) Transmission Control Output circuit at the PCM C4 harness connector.
  NOTE: The test light must illuminate brightly. Compare 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 (T16) TCM Power Control circuit for an open.
  - Perform the 40/41TE VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
TOTALLY INTEGRATED POWER MODULE
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 wire harness and connectors.
2. Pay particular attention to all Power and voltage circuits.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the 40/41TE VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Replace the Totally Integrated Power Module in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
INTERMITTENT WIRING AND CONNECTORS
1. The conditions necessary to set this DTC are not present at this time.
2. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
3. While monitoring the scan tool data relative to this circuit, wiggle test the wiring and connectors.
4. Look for the data to change or for the DTC to reset during the wiggle test.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the 40/41TE VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Test complete.
