  No
  - Go to step 2
CHECK IF THE DTC IS CURRENT
1. With the scan tool, check the Starts Since Set counter for P0868.
  NOTE: This counter only applies to the last DTC set.
  
  Is the Starts Since Set Counter 2 or less?
  
  Yes
  - Go to step 3
  No
  - Go to step 10
CHECK THE PCM AND WIRING
1. Turn the ignition off to the lock position.
2. Remove the Ignition Switch Feed fuse from the TIPM.
  CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being started in gear.
  
  WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in possible serious or fatal injury.
3. Install the Transmission Simulator 8333A and the Electronic Transmission Adapter kit.
4. On the Transmission Simulator select the "OFF" position of the "Input/Output Speed" switch.
5. Ignition on, engine not running.
6. With the scan tool, monitor the Line Pressure during the following steps.
7. Using the Transmission Simulator, set the rotary knob to each of the three line pressure positions.
  NOTE: All three scan tool Line Pressure readings should be steady and ± 14 kPa or 2.0 psi (0.2 of a volt) of the reading specified on the Transmission Simulator.
  
  Did the Line Pressure read within ± 14 kPa or 2.0 psi (0.2 of a volt) in all three positions?
  
  Yes
  - Go to step 4
  No
  - Go to step 6
CHECK THE LINE PRESSURE SENSOR
1. Turn the ignition off to the lock position.
2. Disconnect the Transmission Simulator 8333A and reconnect all previously disconnected connectors.
3. Install a Pressure Gauge, 0 to 2000 kPa or 0 to 300 psi to the L/R test port.
4. Start the engine in park.
5. Monitor the line pressure readings of both the scan tool and the pressure gauge and compare the two readings.
  Is the line pressure gauge reading within 34 kPa or 5 psi of the scan tool reading?
  
  Yes
  - Go to step 5
  No
  - Replace the Line Pressure Sensor in accordance with the Service Information.
  - Perform the 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
CHECK FOR A PLUGGED TRANSMISSION OIL FILTER
1. Turn the ignition off to the lock position.
2. Remove and inspect the Transmission Oil Pan for excessive debris in accordance with the Service Information.
3. Remove and inspect the Transmission Oil Filter in accordance with the Service Information.
  Does the Oil Pan contain excessive debris and/or is the Transmission Oil Filter plugged?
  
  Yes
  - Repair as necessary. If the Transmission Oil Filter is plugged or there is excessive debris, refer to the Service Information for the proper Hydraulic repair procedure.
  - Perform the 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Repair internal transmission and inspect the Transmission Oil Pump in accordance with the Service Information and replace if necessary.
  - Perform the 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .

1. Disconnect the Transmission Simulator 8333A and the Electronic Transmission Adapter kit.
2. Reconnect all previously disconnected connectors except the Line Pressure Sensor/Variable Force Solenoid Assembly harness connector.
3. Ignition on, engine not running.
4. Measure the voltage of the (T854) 5-volt Supply circuit.
  Is the voltage above 5.5 volts?
  
  Yes
  - Repair the (T854) 5-volt Supply circuit for a short to voltage.
  - Perform the 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 7
CHECK THE (T854) 5-VOLT SUPPLY CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C2 harness connector.
3. Disconnect the Line Pressure/Variable Force Solenoid harness connector.
4. Measure the resistance of the (T854) 5-volt Supply circuit between the PCM C2 harness connector and the Line Pressure Sensor/Variable Force Solenoid Assembly harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T854) 5-volt Supply circuit for an open.
  - Perform the 40/41TE VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 8
CHECK THE (T854) 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO GROUND
