WARNING: This page is about a different variant/trim than selected.
  1. CHECK IF DTC IS CURRENT 
    1. Using the scan tool, read TCM DTCs.
    2. Record the Environmental Data and any DTCs.
    3. Clear DTCs.
    4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
    5. Read TCM DTCs.

      Did the DTC reset?

      Yes 

      • Go To  2

      No 

      • Go To  5
  2. CHECK THE (T118) BANK 2 SOLENOID POWER CIRCUIT FOR A SHORT TO VOLTAGE 
    1. Turn the ignition off to the lock position.
    2. Disconnect the Transmission C1 harness connectors.
    3. Disconnect the TCM C1 harness connector.
    4. Turn the ignition on.
    5. Measure the voltage of the (T118) Bank 2 Solenoid Power circuit between ground and the Transmission C1 harness connector.

      Is the voltage above 0.5 of a volt?

      Yes 

      No 

      • Go To  3
  3. CHECK THE (T802) SHIFT SOLENOID B (2) CONTROL CIRCUIT FOR A SHORT TO VOLTAGE 
    1. Measure the voltage of the (T802) Shift Solenoid B (2) Control circuit between ground and the Transmission C1 harness connector.

      Is the voltage above 0.5 of a volt?

      Yes 

      No 

      • Go To  4
  4. CHECK THE SHIFT SOLENOID B (2) 
    1. Turn the ignition off to the lock position.
    2. Measure the resistance of the Shift Solenoid B (2) between the appropriate terminals of the Transmission C1 harness connector.

      Is the resistance of the Shift Solenoid B (2) between 10 and 11 Ohms at 20° C (68° F)?

      Yes 

      • Using the schematics as a guide, check the Transmission Control Module (TCM) pins, terminals, and connectors 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 TCM in accordance with the Service Information. Refer to REMOVAL .
      • Perform TRANSMISSION VERIFICATION TEST. Refer to 6F24 TRANSMISSION VERIFICATION TEST  .

      No 

      • Remove the transmission side cover and inspect the internal lead frame. If there are no problems found with the lead frame, replace the Shift Solenoid B (2) in accordance with the Service Information.
      • Perform TRANSMISSION VERIFICATION TEST. Refer to 6F24 TRANSMISSION VERIFICATION TEST  .
  5. CHECK WIRING AND CONNECTORS 
    1. The conditions necessary to set the 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. Check for any Service Bulletins that may apply.

      Were there any problems found?

      Yes 

      No
