____ GRD TEST MODE. This will remove faults that are corrected from the MCDP memory.
 S 742-022
 (3)  Do MCDP test 01.
 NOTE: The MCDP shows FCC # FAIL if the FCC had a self-test failure
____ when it went into the GRD TEST MODE. The MCDP shows FCC # interface faults if FCC the passed the self-test. The MCDP does not test LRUs or input signals. Each FCC is tested independently as set by the MCDP operator.
 S 862-023
 (4)  Put the airplane back to its usual condition if no other ground tests are necessary.

 WARNING: DO SPOILER/SPEEDBRAKE DEACTIVATION PROCEDURE (MM 27-61-00).
_______ IT IS NECESSARY TO MOVE THE THRUST LEVERS DURING THIS TEST WHICH CAN CAUSE SPEEDBRAKE MOVEMENT IF HYDRAULIC POWER IS ON. THIS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
 (1)  Do Spoiler/Speedbrake Deactivation procedure (Ref 27-61-00).
 S 862-183
 CAUTION:_______MAKE SURE THE ENGINES ARE NOT IN OPERATION. THIS TEST INCLUDES AUTOMATIC MOVEMENT OF THE THRUST LEVERS AND COULD CAUSE AIRPLANE MOVEMENT IF THE ENGINES ARE IN OPERATION. INJURY TO PERSONS COULD OCCUR.
 (2)  
Make sure the engines are not in operation.

 (3)  
Do the "Prepare to Test" steps.

 (4)  S 862-025If the test is to be done after an LRU replacement or a fault correction, make sure the MCDP is put out of GRD TEST MODE. Go into the FLT FAULTS MODE or set the MCDP to OFF and then go into the GRD TEST MODE again.
 NOTE:____ Before MCDP Test 02-TMC is done, put the MCDP out of the GRD TEST MODE. This will remove faults that are corrected from the MCDP memory.
 (5)  S 862-029On the P5 panel, set the L and R ENG LIMITER switches on the ENGINE START/RAM AIR TURB control panel to ON.
 (6)  S 862-040On the P5 panel, set the L and R ELEC ENG CONTROL switches to ON.
 (7)  S 742-035Set the left and right EEC GND TEST switches to the up (ON) position. This will supply power to the EEC. The EEC GND TEST switch is below each EEC unit in the main equipment center.
 NOTE:____ If you do not supply power to the EEC before you set the MCDP ground test mode, these messages will show during the test:
 NO INFC TMC EEC L BUS IN NO INFC TMC EEC R BUS IN
 (8)  S 742-036Do MCDP Test 02
 NOTE:____ The MCDP shows TMC FAIL if the TMC had a self-test failure when it went into the GRD TEST MODE. If no TMC message shows, the MCDP shows messages to clear the thrust lever system and set the A/T switch to ARM. The MCDP then shows TMC interface faults related to the autothrottle servo. The TMC test does not do a check of the LRUs or the input signals.
