DAS test mode and View Trigger (VT) check
Two more source-defined checks from the same §5.3.1 diagnostic tree — running the DAS itself in a dedicated test mode from the DCA, and scoping the 0.8 ms View Trigger clock at the GCIFA and OPCONTA PWBs — separate an internal DAS fault from an OPCONTA/GCIFA/console fault, and a bad GCIFA or OPCONTA board from a bad KGTSM connection.
Applies to
Aquilion 16 (TSX-101A) — Data Transfer (MUDAT) section, source volume 2D201-059E*D, §5.3.1(4)-(5) (p.92). This sits directly after [Manual check and console test for locating MUDAT faults](toshiba-ct-aquilion16-mudat-manual-console-check) (§5.3.1(2)-(3), p.74-75) and the console-test reference tables it depends on (§5.3.1(3), Tables 5.3-1 to 5.3-16, p.76-91), and directly before [Check LED luminescence with the IR converter (ROT and SOT)](toshiba-ct-aquilion16-mudat-luminescence-check) (§5.4, p.93-96) in the source's own section order — the last two checks named in the [abnormal-image diagnostic tree](toshiba-ct-aquilion16-mudat-abnormal-image-diagnosis) before that tree terminates.
Personnel
1 technician · Intermediate — run the DAS itself in test mode from the DCA test program and read per-channel data with "Calc" to isolate an internal DAS fault from an OPCONTA/GCIFA/console fault; separately, read two on-board LEDs (OPCONTA LED42, GCIFA LED41) to spot a dead View Trigger, then use an oscilloscope to confirm a 0.8 ms TTL clock at two specific board positions (GCIFA 13E-2, OPCONTA 6M-33) with GCIFA SW1-1 forced ON, and again with it restored OFF to confirm the KGTSM-sourced system clock still reaches the OPCONTA. Reliably returning SW1-1 to OFF afterward is mandatory per the source's own closing note. (Skill assessment derived from procedure content — not an OEM-stated skill level.)
