Circuit/System Verification
1. Ignition On, observe the DTC information with a scan tool. Verify no TCM or communication DTCs are set.
瀚慖f any TCM or communication DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code
Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle) for further diagnosis.
2. Raise the drive wheels.
Caution: Support the lower control arms in the normal horizontal position in order to avoid damage to the drive axles. Do not operate the
vehicle in gear with the wheels hanging down at full travel.
3. Support the lower control arms so that the drive axles are in a horizontal position.
4. Engine running, place the transmission into 2nd gear.
5. Observe the scan tool Vehicle Speed parameter. The following should display a similar vehicle speed once the drive wheels are at a speed
above 5 km/h (3 MPH):
* The scan tool Vehicle Speed parameter
* The odometer
6. Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
瀚慖f the DTC resets, replace the ECM.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
* ECM or TCM-Refer to Control Module References (See: Testing and Inspection/Programming and Relearning) for replacement, setup and
programming.
* Perform the Transmission Adaptive Functions (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Description and
Operation/AF40-6 - Automatic Transmission/Transmission Adaptive Functions).
