Auto Test

The "AUTO Test" cycles each valve solenoid and the pump motor (as well as the necessary relays) to check component operation. This test is identical to the "Initialization Sequence." If a malfunction is detected, the EBCM/EBTCM will set DTC(s), which will be displayed upon completion of the test. Perform the test as follows:
1. Ignition "OFF."
2. Install the Scan Tool.
3. Turn ignition to "RUN."
4. Select Special Tests.
5. Select Auto Test.
6. Run the AUTO Test.
7. Note any DTCs set.
