(Operating Components In Specified Order)

Output signals are checked at various actuators to determine component operation. Testing is performed in a cycle in which each component is activated 6 times with a short delay between each activation. A longer delay occurs prior to testing next component. The entire cycle is repeated 3 times, then test is exited automatically.
Test must be performed with shift lever in "P" or "N" position, and vehicle must be stopped. Test cannot be performed while driving vehicle. Output signals can be monitored by watching or listening to appropriate component to be activated. Engine RPM will increase during drive compensation activation and decrease during torque limiting activation. If any signal fails to activate a component, check wire circuit and repair as possible.
This test mode is activated by briefly pressing test button on diagnostic unit button 3 times. LED will flash each time component is activated. Components will be activated in the following order:
- No. 1 Shift Solenoid.
- No. 2 Shift Solenoid.
- Torque Converter Lock-Up Solenoid.
- Line Pressure Solenoid.
- Warning Indicator Light In Instrument Panel Flashes.
- Fault Indication Signal (OBD-II) Malfunction Indicator Light.
- Torque Limiting Signal (TCT).
- Drive Compensation For Idling.
- Torque Limiting Signal TC2 When Engine Idling.
- Torque Limiting Signal TC1 When Engine Idling.

NOTE: Engine idle speed will change during drive compensation, TC1 and TC2 activation.
