Error-cause identification flowchart (block test to isolate SRU/HV cable)
Work this OEM flowchart — run the XC Maintenance Program block test, then compare the unacceptable block(s) against the SRU-L or SRU-H inverter ranges, checking the HV cable along the way — as a standalone fault-isolation tree for an X-ray/HV error the other §8.2 flowcharts could not run to ground on their own (source §8.2.13, p.90).
Applies to
Aquilion 16 (TSX-101A) — X-ray & HV volume, source 2D201-064 §8.2.13 (p.90), the last of the thirteen §8.2 fault-isolation flowcharts (8.2.1-8.2.13).
Personnel
1 technician · Intermediate — running the XC Maintenance Program block test (§8.4.8) to read out per-inverter block results, correlating an unacceptable block against the SRU-L inverter range (Nos. 1-10) or the SRU-H inverter range (Nos. 11-19), then escalating to an SRU-L/SRU-H swap or an HV-cable check/replace when the block test alone does not clear the fault.
