Diagnostic Test

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

When Monitored:

Ignition on, engine running.

Set Condition:

Solenoid resistance is greater than or equal to 100k Ohms for more than 100 ms.

Possible Causes
(T810) SHIFT (ON/OFF) SOLENOID 3 SHORT TO GROUND
(T810) SHIFT (ON/OFF) SOLENOID 3 SHORT TO ANOTHER CIRCUIT
SHIFT (ON/OFF) SOLENOID 3
TRANSMISSION CONTROL MODULE (TCM)

Always perform the AS68RC Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to Standard Procedure .

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 7.
CHECK THE (T810) SHIFT (ON/OFF) SOLENOID 3 CONTROL CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the Transmission Solenoid Assembly C2 harness connectors.
3. Disconnect the TCM C3 harness connector.
  NOTE:
  Check connectors - Clean/repair as necessary.
4. Measure the resistance of the (T810) Shift (On/Off) Solenoid 3 Control circuit between the Transmission Solenoid Assembly C2 harness connector and the TCM C3 harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 3.
  No
  - Repair the (T810) Shift (On/Off) Solenoid 3 Control circuit for an open.
  - Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .
CHECK THE (T810) SHIFT (ON/OFF) SOLENOID 3 CONTROL CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between ground and the (T810) Shift (On/Off) Solenoid 3 Control circuit.
  Is the resistance below 100k Ohms?
  
  Yes
  - Repair the (T810) Shift (On/Off) Solenoid 3 Control circuit for a short to ground.
  - Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .
  No
  - Go To 4.
CHECK THE (T810) SHIFT (ON/OFF) SOLENOID 3 CONTROL CIRCUIT SHORT TO VOLTAGE

1. Ignition on, engine not running.
2. Measure the voltage of the (T810) Shift (On/Off) Solenoid 3 Control circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T810) Shift (On/Off) Solenoid 3 Control circuit for a short to voltage.
  - Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .
  No
  - Go To 5.
CHECK THE (T810) SHIFT (ON/OFF) SOLENOID 3 CONTROL CIRCUIT FOR A SHORT TO ANOTHER CIRCUIT

1. Turn the ignition off to the lock position.
2. Measure the resistance between the (T810) Shift (On/Off) Solenoid 3 Control circuit and all other circuits in the Transmission Solenoid Assembly C2 harness connector.
  Is the resistance below 100k Ohms between the (T810) Shift (On/Off) Solenoid 3 Control circuit and any other circuit in the Transmission Solenoid Assembly harness connector?
  
  Yes
  - Repair the (T810) Shift (On/Off) Solenoid 3 Control circuit for a short to another circuit(s).
  - Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .
  No
  - Go To 6.
CHECK THE SHIFT (ON/OFF) SOLENOID 3

1. Turn the ignition off to the lock position.
2. Reconnect the Transmission Solenoid Assembly C2 Harness connector.
3. Measure the resistance of the Shift (On/Off) Solenoid 3 between the (T810) Shift (On/Off) Solenoid 3 and ground at the TCM C3 harness connector.
  Is the resistance of the Shift (On/Off) Solenoid 3 13.0 Ohms (± 2 Ohms)?
  
  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.
  - Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .
  No
  - Replace the Shift (On/Off) Solenoid 3 in accordance with the Service Information.
  - Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .
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
  - Repair as necessary.
  - Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .
  No
  - Test Complete.
