1. Turn the ignition off.
2. Disconnect the ECC Solenoid harness connector.
3. Ignition on, engine not running.
4. Using a 12-volt test light, jump across from the (T316) Shift Motor Control B circuit and the (T315) Shift Motor Control A circuit in the ECC Solenoid harness connector.
5. With the scan tool, actuate the ECC Solenoid.
  Does the test light illuminate brightly and flash on and off?
  
  Yes
  - Go To 6.
  No
  - Go To 3.

1. Turn the ignition off.
2. Disconnect the DTCM harness connector.
3. Measure the resistance between ground and the (T316) Shift Motor Control B circuit at the ECC Solenoid harness connector.
  Is the resistance below 100 Ohms?
  
  Yes
  - Repair the short to ground in the (T316) Shift Motor Control circuit.
  - Perform the DTCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 4.

  - Perform the DTCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
INTERMITTENT 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 test the wiring harness and connectors while checking for shorted and open circuits.
4. Using the scan tool, monitor the data related to this circuit while performing the wiggle test. Look for the data to change or for the DTC to reset.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the DTCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Test complete.
