Diagnostic Test

  1. CHECK IF THE 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.
      NOTE:

      It may be necessary to road test the vehicle to duplicate the original set conditions.

    5. Read TCM DTCs.

      Did the DTC reset?

      Yes 

      • Go To  2

      No 

      • Go To  4
  2. CHECK THE B1 PRESSURE CONTROL LINEAR SOLENOID

    1. Turn the ignition off to the lock position.
    2. Disconnect TCM harness connector and remove the TCM from the transmission.
    3. Measure the resistance of the B1 Pressure Control Linear Solenoid between the appropriate terminals of the TCM transmission connector.

      Is the resistance 6.0 Ohms (± 0.2 of an Ohm)?

      Yes 

      • Go To  3

      No 

  3. CHECK THE B1 PRESSURE CONTROL LINEAR SOLENOID FOR A SHORT TO GROUND

    1. Measure the resistance of the B1 Pressure Control Linear solenoid between ground the appropriate terminals of the TCM transmission connector.

      Is the resistance below 100k Ohms?

      Yes 

      No 

      • 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 MODULE, TRANSMISSION CONTROL (TCM), REMOVAL .
      • Perform the AW60T VERIFICATION TEST. Refer to AW60T TRANSMISSION VERIFICATION TEST  .
  4. CHECK THE WIRING AND CONNECTORS 
    1. The conditions necessary to set this DTC are not present at this time.
    2. Use the Freeze Frame Data to help duplicate the conditions in which the DTC originally set. Pay particular attention to the DTC set conditions, such as, VSS, MAP, ECT, and Load
    3. Using the schematics as a guide, visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or partially broken wires.
    4. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.
    5. Wiggle the wiring and connectors while checking for any possible open or shorted circuits.
    6. Check for any Service Information Updates or Technical Service Bulletins that may apply.

      Were there any problems found?

      Yes 

      No
