 3. Fault Confirmation
__________________
 A. Do this test:

 (1) Make sure that:

 - the SW PARK BRK CTL (73GG) is set to OFF,

 - the Nose L/G is compressed,

 - no towing arm is installed.

 (2) Operate the FWD or AFT cargo-compartment door with the Yellow electric pump (Ref. AMM TASK 52-30-00-860-001) and (Ref. AMM TASK 52-30-00-860-002).

 (3) Do a check of the PTU for continuous running during the operation of the cargo-compartment door.

 (4) Make sure that the the cargo-compartment door is fully opened or closed.

_______________

 **ON A/C 001-049, 051-058, 101-101,
 A. If the PTU runs during the operation of the cargo-compartment door:
 NOTE : Make sure that a second person operates one cargo-compartment door
____ during all checks for 28 VDC in the subsequent procedure.
 - do a check for 28 VDC between: the SOL VALVE-PTU, Y (3012GL) connector A/A and the connector A/B (Ref. ASM 29-23/01).
 (1) If there is 28 VDC:

 - replace the SOL VALVE-PTU, Y (3012GL) (Ref. AMM TASK 29-23-51-000-002) and (Ref. AMM TASK 29-23-51-400-002).

 (2) If there is no 28 VDC:

 - do a check for 28 VDC at the:

 - RELAY CTL (3811GX) connector B1 (Ref. ASM 29-23/01).

 (a) If there is 28 VDC:

 - do a check and repair the wiring between the RELAY CTL (3811GX) connector B1 and the SOL VALVE-PTU, Y (3012GL) connector A/B (Ref. ASM 29-23/01).
