Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.

CHECK IF THE DTC IS CURRENT
1. With the scan tool, read DTCs.
  Is the status Active or is the Starts Since Set counter 0 for this DTC?
  
  Yes
  - Go To 2.
  No
  - Go To 5.
CHECK THE TRANSMISSION CONTROL RELAY
1. Turn the ignition off to the lock position.
2. Disconnect the Transmission Control Relay.
3. Install a substitute relay.
4. Ignition on, engine not running.
5. With the scan tool, read DTCs.
  Is the status Active or is the Starts Since Set counter 0 for this DTC?
  
  Yes
  - Go To 3.
  No
  - Replace the Transmission Control Relay.
  - Perform the 42RLE TRANSMISSION VERIFICATION TEST. Refer to 42RLE TRANSMISSION VERIFICATION TEST .

1. Remove the Transmission Control Relay.
2. Ignition on, engine not running.
3. Measure the voltage at the (T16) Transmission Control Output circuit in the Transmission Control Relay connector.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T16) Transmission Control Output circuit for a short to voltage.
  - Perform the 42RLE TRANSMISSION VERIFICATION TEST. Refer to 42RLE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 4.
CHECK THE (T15) TRANSMISSION CONTROL CIRCUIT FOR A SHORT TO VOLTAGE

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C4 harness connector and connect the PCM Pinout Box (special tool #8815A, Kit, NGC, 38 Position).
  CAUTION:
  Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the (special tool #8815A, Kit, NGC, 38 Position) to perform diagnosis.
3. Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.
4. Disconnect the TIPM C1 harness connector.
5. Ignition on, engine not running.
6. Measure the voltage of the (T15) Transmission Control circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T15) Transmission Control circuit for a short to voltage.
  - Perform the 42RLE TRANSMISSION VERIFICATION TEST. Refer to 42RLE TRANSMISSION VERIFICATION TEST .
  No
  - Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the PCM in accordance with the Service Information. With the scan tool, perform Quick Learn.
  - Perform the 42RLE TRANSMISSION VERIFICATION TEST. Refer to 42RLE TRANSMISSION VERIFICATION TEST .
CHECK WIRING AND CONNECTORS
1. The conditions necessary to set this DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
  Where there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the 42RLE TRANSMISSION VERIFICATION TEST. Refer to 42RLE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
